Advanced semiconductor materials in power electronic switches for energy-efficient converters in an electric vehicle charging system with closed-loop FOPID control

Abstract

The growth in consumer use of electric vehicles is influencing the electrification of transportation in greener and more energy-efficient ways. The availability of high-speed charging stations is crucial to the commercial viability of electric vehicles (EVs). This article examines the development, evaluation, and next steps for several Vienna converter topologies for DC fast-charging systems. The designs and evaluations of these converters are provided, reviewed, and contrasted. The work primarily focuses on several Vienna rectifier topologies on DC quick charging stations that result in fewer CO2 emissions in EV charging stations, aiding in climate action and sustainable development goals. Open-loop and closed-loop charging systems are also discussed in this study to provide improved charging efficiency. The closed-loop system is developed with PI and FOPID controllers; the system is simulated in MATLAB Simulink, and the outputs are obtained to produce a system with higher efficacy. The outputs of the two controllers were compared in terms of time domain metrics like rise time, peak time, settling time, and steady-state error. Results are compared, and it is discovered that the closed-loop charging system with the Vienna rectifier and FOPID controller works better in every way. When charging an EV battery, the performance and efficiency of the Vienna converter circuit, a power electronic switching device, depends on its material qualities. Typically, these switches are constructed from silicon. Switching devices use broad-band semiconductors because of developments in material science and a need for higher performance. This work also discusses the semiconductor material used to create the power electronic switches used in the Vienna Converter.
