Abstract
Integration of renewable energy sources to the grid-connected system has influenced scholarly research in recent times to evolve solutions for power electronic conversion. Particularly, solar photovoltaic (SPV), being a resource available throughout the year, demands needful research to meet the demand for industrial applications. To facilitate SPV, multilevel inverters (MLIs) and cascaded H-bridge inverters (CHBIs) are proposed in the literature to meet the power requirement. However, these circuits suffer from efficiency loss, economic aspects of DC sources usage, and switching losses. Hence, in this research, a new power converter topology is projected to improve the overall efficiency of SPV systems. Further, a three-level approach involving (i) SPV Panel-Temperature Reduction (SPV-PTR) Setup, (ii) Boost Multilevel Direct Current Link Converter (BMLDCLC), and (iii) use of effective snubber modules (SM) are effectively handled to promote the industry readiness of the proposed system. From a detailed system investigation, it is seen that the proposed arrangement has minimized the power loss to ensure better quality in output. Furthermore, the software-based results and hardware setup of the planned comprehensive converter have shown promising results in terms of (i) reduced voltage stress, (ii) reduced total harmonic distortion (THD) without filter component, and (iii) reduced power loss. It is observed that the experimental setup has reported a 12.9% of excess heat removal, 5% decrease in harmonics, and 33% switch reduction than the existing MLI schemes. In addition, the proposed setup is suggested to apply for industrial purposes indicate its efficacy to be a solution in real time.
Highlights
Alarming environmental concerns and exhaustion of fossil fuels have invoked the necessity of eco-friendly power generation via renewable energy resources [1]
From the the same is recommended for real-time operexamination, it is authenticated that the 3rd, 5th, and 7th-order harmonics are mitigated through the switching schemes
The comparative study confirms that the proposed 7-level Boosted Multilevel DC-Link Converter (BMLDCLC) system has only utilized 33.33% switches compared to other conventional multilevel inverters (MLIs) schemes
Summary
Alarming environmental concerns and exhaustion of fossil fuels have invoked the necessity of eco-friendly power generation via renewable energy resources [1]. Having the superiority to reduce greenhouse emissions, renewable energy is considered as one of the essential tools to avoid energy import. SPV systems have gained monumental recognition to emerge as a resource of the decade. Harmless operation, abundant availability, and easy portability are its inherent merits over other renewable energy resources. SPV modules are constant voltage sources fed to a load via power conditioning circuits. Fabricating an efficient and cost-effective converter prototype model is really challenging. Since the power conditioning circuitries are implemented over two or three-level converters, interfacing PV panels for high power application become complex
