Outside-in enhancement of phosphate solubilizing bacteria by sludge biochar for phenol remediation in soil: Pollution stress reduction, electron transfer gain and secretion regulation

The high toxicity of phenol poses a significant barrier to bacterial bio-removal capacity. This study innovatively proposes the utilization of sludge biochar (SB) to embed phosphate-solubilizing bacteria (CZB1), creating a composite system (SB-CZB1) that enhances the bio-removal efficiency of phenol. The research findings indicate that after being embedded with biochar, Phosphorus solubilizing bacteria (PSB) achieved a significant enhancement (49.7 %-67.0 %) in phenol removal efficiency across different concentration gradients (1500, 2000, 2500 mg/L). SB component in the SB-CZB1 composite system provides a stable and favorable growth environment for CZB1, significantly enhancing microbial metabolic activity. Notably, it stimulates CZB1 to secrete succinic acid and malic acid (with increases of 3.8 % and 23.9 %, respectively), effectively mitigating the detrimental effects of phenol toxicity on microorganisms. Three-dimensional fluorescence and electrochemical analysis demonstrate that SB not only exhibits exceptional electrochemical performance but also stimulates CZB1 to generate redox-active substances (quinone components in humic acid). The electron transfer rates between microorganisms and phenol in the SB-CZB1 system are 9.75–21.71 times and 23.94–63.95 times higher than those in SB and CZB1 alone, respectively. Meanwhile, the abundant oxygen-containing functional groups (COH/COC, COOH, CO) on the surface of SB-CZB1 play a pivotal role in the adsorption and removal of phenol. Furthermore, pot experiments further reveal that the SB-CZB1 composite system significantly enhances the removal efficiency of phenol in soil (98.1 %). Additionally, the application of SB-CZB1 effectively modulated soil properties, notably increasing available potassium and available phosphorus content by 40.86 % and 136.69 %. This application not only enriched soil microbial diversity but also promoted the proliferation of native organic pollutant remediation bacteria in the soil. Notably, the proliferation of Bacillus species affiliated with CZB1 was the most significant, increasing by 82.1 %. This result confirms that biochar embedding technology effectively enhanced the colonization of CZB1 in the soil, thereby significantly accelerating the bio-removal process of phenol.

Beyond the g-Value: A comparative study of solar control coated glass and spectrally selective glass in terms of building energy efficiency

The thermal efficiency of transparent envelopes is a key factor in building energy consumption and indoor thermal comfort, with the g-value being a critical metric for evaluating these effects. Solar control film glass and low-emissivity (Low-E) glass, recognized for their distinct advantages, are extensively used in construction. However, comprehensive research on their photothermal properties, especially regarding spectral and angular dependencies, remains limited. In this study, a meticulous field experiment was conducted under six distinct conditions during both winter and summer to examine the thermal performance between solar control coated glass (SCCG) and spectrally selective glass (SSG). The results show that, despite having similar heat transfer and solar heat gain coefficients, their indoor peak temperatures can differ by 1.2 °C to 5.6 °C under typical sunny conditions, and variations in cooling and heating energy consumption range from 6.9 % to 14.4 %. Further analysis reveals that the standard g-value overestimates the solar heat gain of SSG by approximately 10 %, with significant discrepancies in the direct transmission heat and secondary heat transfer of 17.8 % and 37.4 %, respectively. In contrast, the standard g-value is more suitable for SCCG, with a measured g-value that is only 1.2 % higher than the standard g-value. The spectral and angular dependencies of both glasses were also compared in this study, and SSG was found to have a strong spectral dependence and a higher angular dependence than SCCG. These findings indicate that SCCG is more beneficial for energy conservation in cold climates when the thermal parameters are identical. Moreover, the research underscores the limitations of current standards and calculation methods for evaluating solar heat gain in transparent envelopes, particularly for glasses with spectral selectivity.

A General On-Orbit Absolute Radiometric Calibration Method Compatible with Multiple Imaging Conditions

On-orbit absolute radiometric calibration is not only a prerequisite for the quantitative application of optical remote sensing satellite data but also a key step in ensuring the accuracy and reliability of satellite observation data. Due to the diversity of imaging conditions for optical remote sensing satellite sensors, on-orbit absolute radiometric calibration usually requires a large number of imaging tasks and manual labor to calibrate each imaging condition. This seriously limits the timeliness of on-orbit absolute radiometric calibration and is also an urgent problem to be solved in the context of the explosive growth of satellite numbers. Based on this, we propose a general on-orbit absolute radiometric calibration method compatible with multiple imaging conditions. Firstly, we use a large amount of laboratory radiometric calibration data to explore the mathematical relationship between imaging conditions (row transfer time, integration level and gain), radiance, and DN, and successfully build an imaging condition compatibility model. Secondly, we combine the imaging condition compatibility model with cross calibration to achieve a general on-orbit absolute radiometric calibration method. We use cross calibration to obtain the reference radiance and corresponding DN of the target satellites, which calculates the general coefficient by using row transfer time, integration level, and gain, and use the general coefficient to calibrate all imaging conditions. Finally, we use multiple imaging tasks of the JL1GF03D11 satellites to verify the effectiveness of the proposed method. The experiments show that the average relative difference was reduced to 2.79% and the RMSE was reduced to 1.51, compared with the laboratory radiometric calibration method. In addition, we also verify the generality of the proposed method by using 10 satellites of the Jilin-1 GF03D series. The experiment shows that the goodness of fit of the general coefficient is all greater than 95%, and the average relative difference between the reference radiance and the calibrated radiance of the proposed method is 2.46%, with an RMSE of 1.67. To sum up, by using the proposed method, all imaging conditions of optical remote sensing satellite sensor can be calibrated in one imaging task, which greatly improves the timeliness and accuracy of on-orbit absolute radiometric calibration.

A Bayesian transfer sparse identification method for nonlinear ARX systems

SummaryIn this paper, we design a transfer sparse identification algorithm under the Bayesian framework through introducing other system knowledge into the system to be identified. This method provides a new identification solution for a nonlinear autoregressive model with exogenous inputs (NARX). The estimates of the transferred parameters are calculated by adding the transfer correction term to the un‐transferred estimates. To achieve this, a joint prior distribution is devised for the parameters, ultimately enhancing the efficient utilization of existing data, reducing the reliance on new data, and achieving more accurate identification. The maximized marginal likelihood method is used to find the transfer gain and the transfer information matrix in the transfer correction term. Meanwhile, in order to make the algorithm automatically adapt to different data, we design an automatic structure detection method based on the transfer framework. The method automatically determines the sparsity threshold based on the maximum inter‐class variance. Two examples are provided to demonstrate the advantages of our algorithm.

A transfer sparse identification method for ARX model

AbstractThe aim of this paper is to improve the parameter estimation accuracy of the system to be identified by using measurements from a known system. By introducing the transfer gain matrix and setting the effective identification criterion, a novel transfer sparse identification method is raised, which deals with the sparse issues more precise. Besides, the unbiased form is given in the parameter analysis and the recursion form can prevent the dimension catastrophe related problems. Moreover, in order to test the effects of the transfer and avoid bad performance, a negative transfer analysis condition is carried out. Finally, the simulation verifies the enhancements and benefits of the proposed transfer sparse identification method, confirming that the transfer performance outperforms better than that of no transfer, especially on the zero parameters identification.

Optimized ultra high voltage gain DC–DC converter with current stress reduction for photovoltaic application

AbstractThis paper presents a non‐isolated DC‐DC converter designed to validate ultra‐high voltage gain using a modified double boost mode. The objective is to achieve exceptionally high voltage gain by integrating a modified triple boost technique (MTBT), interleaved with second main and auxiliary third MOSFETs, and a modified switched inductor‐capacitor (MSLC), effectively doubling the voltage transfer gain. Furthermore, MSLC is combined with the auxiliary third and double main MOSFET to double the voltage gain while concurrently mitigating voltage stress on the auxiliary MOSFET and diodes in the proposed converter (the PC). Additionally, all diodes in the MTBT operate under zero current switching (ZCS) and the double main and auxiliary third MOSFET face very low current stress at ultra‐high voltage gain. The input current of the PC remains steady without pulsating at a low duty ratio, making the PC more suitable for renewable energy systems. The PC offers numerous advantages, exhibiting high efficiency and ensuring minimal voltage stress on power devices with low current stress on the power switches. Notably, PC aims to elevate input voltages from 30 V to a variable output range of 335 to 600 V, delivering 440 watts at 96.1% efficiency.

A Single-Switch WPT Circuit With Inherent CCO–CVO for Battery Charging

In order to obtain a highly reliable and low-cost wireless charging method. This paper proposes a single-switch wireless power transfer (WPT) circuit with inherent constant current output (CCO) and constant voltage output (CVO) for battery charging. Compared with a full bridge WPT circuit, the structure and control strategy of the proposed circuit is simple. And the shoot-through problem could be avoided in the proposed circuit. In order to realize the inherent CCO-CVO without the wireless communication and extra control circuit, the double-D quadrature (DDQ) coils are used in this paper to remove cross-coupling between coils. And the corresponding compensation network is designed to realize the automatic transition from the CCO to CVO. There are no active control schemes used in the proposed method. The compensation design could enable primary-side protection of over-current against the accidental removal of the secondary side. There is no compensation inductor in the secondary circuit, which reduces the volume and weight of the secondary circuit. Moreover, the transfer gain does not rely on the transformer parameters, and more parameters design freedom can be realized. Finally, the simulation and the experimental verification are carried out to verify the superiority of the proposed circuit.

A High-Efficiency DC-DC Converter Based on Series/Parallel Switched Inductor Capacitors for Ultra-High Voltage Gains

A high-efficiency DC-DC converter employing a modified architecture called the hybrid switched inductor–capacitor series (MHSLCS) is proposed in this paper. The primary goal is to achieve a notably ultra-high voltage gain for renewable energy systems (RESs). Furthermore, the use of only one input capacitor in the MHSLCS eliminates pulsations in the input current at both low and high duty ratios. The proposed converter integrates the MHSLCS with a modified switched capacitor (MSC) that interleaves with the main MOSFET, effectively doubling the voltage transfer gain. Additionally, a modified hybrid switched inductor–capacitor parallel (MHSLCP) is incorporated in parallel with an interleaved auxiliary MOSFET. Both MOSFETs, combined with the MSC, contribute to achieving an ultra-high voltage gain. In addition, the inductors of the MHSLCP operate in a discontinuous conduction mode (DCM), which results in significant stress reductions in the power diodes and switches at high output voltages. The advantages of the proposed converter are multifaceted, demonstrating a high efficiency while minimizing the voltage in power device diodes and MOSFETs. The use of low inductance and capacitance values at high switching frequencies further enhances the performance. Wide-bandgap (WBG) power devices are employed to achieve the desired high voltage gain and efficiency. The proposed converter was designed with a PCB and underwent experimental testing to validate laboratory results. The proposed converter boosted the input voltage from 30 V to a variable output voltage between 325 V and 500 V, with a power output of 325 watts and an efficiency of 95.5%.

Study on Split-Capacitors Applied in Positive Output Super-Lift Luo-Converters

Voltage Lift Technique has been successfully employed in design of DC/DC converters, e.g. three series Luo-Converters. However, the output voltage increases in arithmetic progression. Super Lift Technique is the most significant contribution in Power Electronics, e.g. four series Super-Lift Converters. Their output voltage increases in geometric progression. This paper introduces a novel approach – Super Lift Technique Armed by Split Capacitors that implements the output voltage increasing in higher geometric progression. It effectively enhances the voltage transfer gain in power series as well.

Dual‐input single‐output high step‐up DC–DC converter for renewable energy applications

AbstractThis paper introduces a dual‐input single‐output (DISO) non‐isolated DC–DC converter with the capability to accommodate multiple input ports. It supports both bidirectional and unidirectional power flows. The proposed converter employs the switched‐capacitors (SC) technique, resulting in a high‐ voltage transfer gain. Although the use of the SC technique leads to discontinuous input current, this issue has been addressed by incorporating an inductor at the input side. The DISO high‐voltage gain converter offers flexible control options, reduces current and voltage stress on semiconductors, and imposes no duty cycle limitations due to the proposed switching methods. Furthermore, when Port 2 fails, the proposed converter can transfer energy to the load by sources in Port 1 without interruption. The steady‐state model and small‐signal analysis (SSA) of the proposed converter are examined at continuous conduction mode (CCM). To evaluate accurately, the proposed converter is compared with the recently presented converters based on important characteristics. Additionally, a comprehensive power loss analysis is performed. Following the design specifications, an evaluation and testing of a prototype are conducted to verify the feasibility and performance of the converter.

Energy transfer and laser gain cross-section analysis in Nd-Yb-Gd doped CaF2 crystals

A detailed spectroscopic characterization of CaF2 co-doped with neodymium and ytterbium ions is presented. The higher Nd3+ absorption cross-section around 791 nm than Yb3+ around 980 nm enables an efficient excitation of Yb3+ ions by pumping Nd3+ with a subsequent energy transfer (ET) from Nd3+ to Yb3+ ions. By combining Nd3+ and Yb3+, along with Gd3+ buffer ions Nd3+,Yb3+,Gd3+:CaF2 crystals exhibit very large emission bands extending the usual Yb3+ emission spectrum by adding the Nd3+ emission contribution at longer wavelengths. The Nd3+ ⟶ Yb3+ energy transfer efficiency is estimated using two different approaches based on luminescence intensity measurements and lifetimes, giving consistent results. An energy transfer efficiency of 80 % is achieved in CaF2:0.5%Nd,3%Yb,2%Gd illustrating the ET strength within Nd3+-Yb3+ clusters. Finally, a detailed study of the gain cross-sections and laser emission spectra, and their dependence with Yb3+ doping concentration and population inversion is carried out, providing a detailed model of the laser spectral dynamics in such crystals. The gain cross-section is either dominated by one of the Nd3+ peaks at 1065 nm or 1048 nm or exhibits a flat profile covering the 1045–1067 nm range, in which case the laser oscillates randomly over this spectral range. The results highlight the specifics of the Nd3+ four level laser coupled by energy transfer to the Yb3+ quasi three level laser. Among others, this study shows how a large Nd3+ inversion ratio initiates the depletion of the Yb3+2F7/2 ground state through the ET. This depletion then has two effects as it saturates the energy transfer since the number of Yb3+ acceptors diminishes and it also shifts the laser wavelength towards shorter wavelength as the Yb3+ laser reabsorption is weakened.

Ultra‐high voltage gain DC–DC converter based on new interleaved switched capacitor inductor for renewable energy systems

SummaryIn this paper, introduces a DC–DC converter design based on a modified hybrid switched inductor‐switched capacitor architecture, aimed at achieving ultra‐high voltage gain in renewable energy systems (RES). The proposed converter involves adding a modified boosting conversion mode (MBM) that interleaves with the main switch to double the voltage transfer gain. Additionally, a modified switched capacitor (MSC) technique, utilizing two diodes as interleaved components, is integrated into the main and auxiliary switches to verify low voltage stress across them. In addition, modified hybrid switched inductors with capacitors (MSIC) and diodes are employed to validate ultra‐high voltage gain. The main advantages of the proposed converter are its high efficiency, low voltage stress across diodes and MOSFETs, and the utilization of low values of inductors and capacitors at high switching frequencies. In addition, the voltage stress across the inductors of the (MSIC) is reduced as the duty cycle increases. Furthermore, the current stress on the main switch is reduced when the charge of capacitor C1 becomes zero. Mathematical models for both continuous conduction mode (CCM) and discontinuous conduction mode (DCM) of the proposed converter are explored. Furthermore, a dual PI controller is designed for the proposed converter to maintain a high fixed output voltage. In addition, the PCB design and experimental testing of the proposed converter to verify the simulation and laboratory results. Specifically, the proposed converter is designed to boost up voltage (30–40 V) to a variable output voltage between 200 and 300 V at 300 W at efficiency 96.7%.

Dynamic Cerebral Autoregulation After Carotid Endarterectomy.

Studies have shown that dynamic cerebral autoregulation (dCA) is impaired in patients with severe internal carotid artery (ICA) stenosis and that carotid endarterectomy (CEA) may improve dCA in these patients. However, the time course of dCA changes in patients after CEA remains unclear. Therefore, this study aimed to investigate the effects of CEA on the dCA in patients with carotid artery stenosis at different time points. This prospective study enrolled 44 patients (19 symptomatic stenosis patients and 25 asymptomatic stenosis patients) who underwent CEA and 44 age- and sex-matched controls. In the CEA group, the patients underwent dCA measurements at baseline, within 3 days, and 1 month after CEA. Transfer function parameters, phase difference (PD), and gain were used to quantify dCA. Changes in dCA before and after CEA were analyzed in detail. The bilateral PD of the patients before CEA was significantly lower than that of the control group. This damage did not improve within 3 days after surgery. One month after surgery, the PD on the affected side of the patients significantly improved compared with before surgery and reached the level of the control group. The PD of affected side across time points in symptomatic and asymptomatic stenosis patients is consistent with that in all patients. The dCA level did not improve immediately after CEA but significantly improved 1 month after surgery. This suggests that the occurrence of stroke should be considered in the acute period after CEA surgery, and its preventive effect on stroke may be effective after 1 month. We found the dCA level did not improve immediately after CEA but significantly improved 1 month after surgury. This suggests that the occuttencce of stroke and surgical complications (such as cerebral hyperperfusion syndrome) associated with impaired dCA in the acute phase after CEA surgery should be of particular concern.

Stress Training in the Classroom: Evidence of Learning Transfer and Psychological Gains

Stress is ubiquitous in life and creates a need for effective responses in any domain. In this exploratory study, our goal was to understand better how business students learn and use stress management techniques in the classroom context and how this learning applies to different domains. We used thematic coding and textual analysis of weekly student journal reflections about their use of different stress management techniques over 12 weeks. Moving beyond their use of stress techniques in the classroom, students’ comments suggest that their broad use of tools, led to improved well-being (i.e., increased positive affect, reduced stress, and negative affect) beyond the classroom into other life domains. An analysis of student statements further showed increases in their present-focused cognitive orientation, the key dimension of mindfulness, over time. Their heightened present-focused cognitive orientation seems to stem from their practice of the deep breathing stress management technique. Thus, the results suggest that an explicit focus on students’ stress reduction in the classroom may have important implications for how educators can better prepare students for addressing stress and improving psychological and cognitive gains through applied learning across multiple life experiences.

Design and assessment on a bottom-cut shape for latent heat storage tank filled with metal foam

The utilization of phase change materials (PCMs) holds tremendous potential of heat storage domain. The PCM's refractory at the latent heat thermal energy storage (LHTES) unit bottom hinders the heat storage efficiency, despite the significant improvement in thermal conductivity achieved through the addition of metal foam. This study employs numerical simulation to examine the impact of applying bottom cross-cut on PCM's spatial distribution in a horizontal LHTES unit. The manuscript analyzes parameters including melting fraction, complete melting time, Rayleigh number, natural convection heat transfer gain, melting phase interface, velocity and temperature distributions, and heat storage. The findings indicate that the proximity to the heating tube results in a reduction of solid volume at the LHTES unit bottom. A 0.6 bottom cross-cut ratio leads to an 18.84 % faster heat storage rate compared to a concentric-circle unit. Furthermore, a bottom cross-cut ratio of 0.5 enhances natural convection heat transfer gain by 3.28 times.

New Current-Mode Precision Full-Wave Rectifier Employing Single Inverted Z-Copy Current Differencing Buffered Amplifier

This paper aims to introduce a new current-mode precision full-wave rectifier configuration using a single inverted Z-copy current differencing buffered amplifier (IZC-CDBA) and two nMOSFETs. The unique feature of the proposed configuration is that it can simultaneously produce both the inverting and non-inverting rectified outputs without changing its architecture. Only active components make the configuration more suited for IC implementation. Moreover, it features low input impedance and high output impedance, making it fully cascadable. In addition, the new design enjoys extremely high-frequency operations. The effects of non-ideal transfer gain and parasitic impedances on the designed circuit are also explored. PSPICE simulations test the functionality of the proposed circuit for two distinct types of IZC-CDBA realization. The CMOS-based realization is checked through TSMC 0.18 μm level-7 technology parameters. The average DC current output, input dynamic range (± 450 μA), power consumption, temperature, total harmonic distortion, noise, and Monte-Carlo studies are performed to judge the efficiency level. The findings of the simulations match up nicely with the theoretical analysis. RMS and average value computation for a sinusoidal signal are also provided as an application of the suggested full-wave rectifier.

Impaired Dynamic Cerebral Autoregulation as a Predictor for Cerebral Hyperperfusion After Carotid Endarterectomy: A Prospective Observational Study

Cerebral hyperperfusion syndrome (CHS) is a severe complication of carotid endarterectomy (CEA). Because cerebral hyperperfusion (CH) reduces the benefits of CEA, it is important to identify patients at high risk of developing CH. We investigated dynamic cerebral autoregulation (dCA) as a potential predictor of CH after CEA. In a prospective observational study of 90 patients, we defined CH as a ≥100% increase in the transcranial Doppler ultrasound-derived mean flow velocity of the middle cerebral artery compared to baseline, with or without clinical manifestations. We examined dCA in the supine position and during squat-stand maneuvers using the transfer function, analyzing phase, gain, and coherence. Logistic regression analysis and receiver operating characteristic (ROC) curves were used to assess the relationships between variables and outcomes. Cerebral hyperperfusion (CH) occurred in 18 patients after CEA. The CH group had a lower ipsilateral phase for both body postures than the non-CH group at very low and low frequencies, respectively (both P<0.01). Postoperative CH was independently associated with the preoperative peak systolic velocity (PSV)sten/PSVdis ratio and the ipsilateral phase in both body postures at a very low frequency. Receiver operating characteristic (ROC) curve analysis showed that the ipsilateral phase had excellent CH predictive accuracy in the supine position and squat-stand maneuvers at a very low frequency (areas under the curve: 0.809 and 0.839, respectively, both P<0.001; cutoff values: 24.7 and 11.7, respectively). The lower ipsilateral phase may serve as a predictor of CH after CEA.

Modeling and performance analysis of coupled multilayer graphene nanoribbon (MLGNR) interconnects with intercalation doping

This paper investigated the temperature‐dependent performance of coupled top contact multilayer graphene nanoribbon interconnects (TC-MLGNRs) with different intercalation doping (viz., AsF5-, FeCl3-, and Li-doped) considering edge roughness and crosstalk effect, compared with SC-MLGNR, MWCNT, and copper (Cu) interconnects for 13.4 nm technology nodes at the global level. Based on the equivalent single conductor (ESC) modeling, a distributed transmission line model for coupled doped TC-MLGNRs is presented to obtain the crosstalk delay, step response, transfer gain, and 3-dB bandwidth, which considers in-phase and out-of-phase crosstalk modes and verified with the Hspice simulation. It is demonstrated that all interconnects at room temperature in the in-phase crosstalk mode outperform those in the out-of-phase crosstalk mode in terms of crosstalk delay, transfer gain, and 3-dB bandwidth, and Li-doped TC-MLGNR significantly reduces crosstalk delay and enhances transfer gain and 3-dB bandwidth compared to other interconnects. Moreover, it is found that the victim line of two-line coupling for doped TC-MLGNRs exhibits less crosstalk delay, greater transfer gain, and 3-dB bandwidth compared to the center line of three-line coupling for doped TC-MLGNRs in the same condition. Furthermore, we analyze the crosstalk delay and 3 dB-bandwidth for two- and three-line doped TC-MLGNRs at varying temperatures and compare them with SC-MLGNR, MWCNT, and Cu interconnects. Simulation results show that crosstalk delay and bandwidth performance are temperature dependent, and they both degrade with increasing temperature. Also, Li-doped TC-MLGNRs still exhibit the best crosstalk delay and bandwidth performance of all interconnects. The numerical calculation results show that decreasing interconnect temperature, increasing line spacing, and reducing edge roughness are efficient methods to reduce crosstalk delay and enhance 3-dB bandwidth for Li-doped TC-MLGNRs. In addition, the results obtained by the proposed model are well matched with the Hspice simulation. Hence, our performance analysis demonstrates that Li-doped TC-MLGNR can be a promising material for global interconnect applications in a thermally variable environment.

The converter design also includes a modified switched inductor with a modified voltage multiplier mode (MVM), which interleaves with the main switch and effectively doubles the voltage transfer gain. Furthermore, a modified triple boosting mode technique, utilizing interleaved components and an auxiliary switch, is integrated into the converter design. The main switch and auxiliary switch, combined with modified voltage multiplyer, contribute to achieving high voltage gain. The proposed converter offers numerous advantages. It exhibits remarkable efficiency while ensuring low voltage stress across diodes and MOSFETs. Moreover, by utilizing low inductance and capacitance values at high switching frequencies, the converter’s overall performance is enhanced. To validate and substantiate the simulation and laboratory results, the converter has undergone PCB design and experimental testing. Specifically, this converter is designed to boost input voltage levels ranging from 30 V to 40 V to a variable output voltage between 200 V and 400 V, with a power output of 360 W and an efficiency rating of 96.5%.
