Simulation of Solar Powered DC Motor Control Using H-Bridge Converter

In this paper, the solar powered DC motor control system is considered and simulations are performed using various controllers and H-Bridge Buck Boost converter. The parameters varied are: irradiance and temperature. When input parameters are changed abruptly, such as sudden rise or fall in temperature or irradiance, DC motor performance is observed. These parameters are changed separately, keeping other parameter constant. The main aim is to obtain smooth DC motor control and operation under all input conditions. The simulations results are executed and compared for different controllers using MATLAB/SIMULINK environment.

Enhancing the solar still performance using reflectors and sliding-wick belt

This work presents a performance investigation of the rotating wick solar still (RWSS) under different operational and designable conditions. A black jute cloth belt was rotated vertically and horizontally inside the distiller. The effect of the sliding direction (clockwise and counter clockwise) of the wick belt on the performance of RWSS was studied. The performance of the RWSS was studied at various belt sliding speeds of 0.02, 0.05, 0.1, 0.2, and 0.3 min−1. In addition, mirrors were utilized externally and internally with RWSS to aid in concentrating more solar energy onto the system. A solar photovoltaic powered DC motor was used to rotate the belt. It was found that the freshwater distillate of the RWSS was higher than that obtained from the conventional distiller. The optimum performance of RWSS was obtained at 0.05 min−1 and under up-down sliding direction. In addition, the freshwater productivity of RWSS was higher than that of the conventional solar still (CSS) by 300% and 260% with and without reflectors, respectively. The thermal efficiency was 82% and 35% for RWSS and CSS, respectively.

Solar powered UAV model on MATLAB/Simulink using incremental conductance MPPT technique

Purpose The aviation industry has started environment friendly and also conventional energy independent alternative energy dependent designs to reduce negative impacts on the nature and to maintain its future activities in a clear, renewable and sustainable way. One possible solution proposed is solar energy. Solar-powered aerial vehicles are seen as key solutions to reduce global warming effects. This study aims to simulate a mathematical model of a solar powered DC motor of an UAV on MATLAB/Simulink environment. Design/methodology/approach Maximum power point tracking (MPPT) is a critical term in photovoltaic (PV) array systems to provide the maximum power output to the related systems under certain conditions. In this paper, one of the popular MPPT techniques, “Incremental Conductance”, is simulated with solar-powered DC motor for an UAV design on MATLAB/Simulink. Findings The cascade structure (PV cell, MPPT, buck converter and DC motor models) is simulated and tested under various irradiance values, and results are compared to the DC motor technical data. As a result of that, mathematical model simulation results are overlapped with motor technical reference values in spite of irradiance changes. Practical implications It is suggested to be used in real time applications for future developments. Originality/value Different from other solar-powered DC motor literature works, a solar-powered DC motor mathematical model of an UAV is designed and simulated on MATLAB/Simulink environment. To adjust the maximum power output at the solar cell, incremental conductance MPPT technique is preferred and a buck converter structure is connected between MPPT and DC motor mathematical model. It is suggested to be used in solar-powered UAV designs for future developments.

Energy scavenging using vibrations from bluetooth controlled DC motor

Wide spectrum of research for application-based solutions has grown due to the requirement of automation of general electrical appliances. A low-cost solution is presented in this paper to control DC motor using Bluetooth module and controlled by an ARM processor. The main objective here is to build an efficient closed loop system which is wirelessly controlled by ARM processor 2103 using Bluetooth module and Bluetooth dongle. The system suggested here is expandable and can be integrated with latest technologies as well. The paper gives the details of the prototype for home automation system and gives the expected results with 0.1% tolerance. It also suggests the ways to integrate this system with the mobile phones and hence control the devices with the mobile handsets. The vibration frequency of the DC motor is used to generate electrical potential using MEMS tecnonlogy. A novel idea of self powered DC motor is thus presented by installing MEMS based energy harvester on the motor shaft.

Analysis of conducted EMI with standalone solar powered dc motor

The green environment warrants not only researchers, but rather all citizens, to adopt renewable energy sources. One such option is the use of solar energy, especially the conversion of light energy from the sun to electric energy. The conversion of light to electricity with the help of photovoltaic cells (PV), though widely used, has its own problems, such as undesirable electromagnetic interference (EMI), both in radiation and conduction modes. The present research aims to mitigate the unwanted EMI in the conduction mode (to limit the scope of the research). The mitigation of the conducted EMI on a DC/DC buck converter was studied with a standalone 4050 W PV plant. The conducted EMI was measured and the effectiveness of randomization on the spreading of the dominating frequency was examined by a simulation using PSpice software, and the same was validated in real-time measurements. All of the investigations were accomplished using an embedded LPC2129 ARM processor. The theoretical analysis and the experiment results of the conducted noise spectrum were compatible with each other, based on which a randomized duty ratio and a random pulse-position modulation (RPPM) with a fixed carrier frequency scheme were contemplated for adoption.

Performance analysis of a PV powered DC motor driving a 3-phase self-excited induction generator

Photovoltaic (PV) powered DC motors driving dedicated loads (e.g. water pumps) are increasingly used in the remote rural areas of many developing countries. The key to their success is simplicity (direct coupling, no DC-AC inversion, no storage batteries, etc.). In this paper, a PV powered DC motor is used to drive an isolated three-phase self-excited induction generator (SEIG). It is found that due to the unique torque-speed characteristics of the SEIG, utilization efficiency is close to maximum at all insolation levels with no peak-power tracking. The proposed arrangement is useful as part of an integrated renewable energy system (IRES), which takes advantage of the inherent diversity of wind and insolation in most developing countries to improve power quality. The SEIG is driven by wind turbine, DC motor, or both. Performance of the system under different insolation conditions is analyzed.

Speed control of a PV powered DC motor driving a self-excited 3-phase induction generator for maximum utilization efficiency

Photovoltaic (PV) powered DC motors driving dedicated loads (e.g. water pumps) are increasingly used in the remote rural areas of many developing countries. The key to their success is simplicity (direct coupling, no DC-AC conversion, no storage batteries, etc.). Because of the relatively high cost of the PV array, the system designer is interested in maximizing its utilization efficiency. A PV powered DC motor can also be used to drive a three-phase self-excited induction generator (SEIG). This arrangement is useful as part of an integrated renewable energy system (IRES), which takes advantage of the inherent diversity of wind and solar energy in most developing countries to improve power quality. The SEIG is driven by a wind-turbine, DC motor, or both. Another advantage of this arrangement is its versatile control characteristics through the DC motor control. This paper describes a technique to maximize the utilization efficiency of the PV array by controlling the field current of the DC motor through a DC chopper.
