Desing and implementation of electric vehicles bidirectional charger

Abstract

This project aims to enhance the design and implementation of a bidirectional electric vehicle (EV) charger, a vital component in modern energy systems. The bidirectional charger not only facilitates charging and discharging of energy to and from the grid or energy storage systems but also enables efficient energy management and utilization. Additionally, it can serve as a shunt active power filter ,effectively mitigating harmonics generated during power conversion, thereby reducing total harmonic distortion (THD) and ensuring grid reliability. To regulate the operation of this power electronic device, two control techniques were investigated: hysteresis current control (HCC) and model predictive control. Through comprehensive simulation studies, the results obtained from both techniques were presented and compared. Furthermore, real-time evaluations were conducted to validate the efficacy of the employed control techniques. By improving the bidirectional EV charger’s design and employing advanced control strategies, this project contributes to the development of more efficient and reliable energy systems while addressing power quality concerns through harmonic reduction.
