Abstract

The goal of research is to develop an optimized Electric Vehicle (EV) charging system with enhanced efficiency and cost-effectiveness by integrating a High Frequency Resonant Bridgeless (HFRB) Power Factor Correction (PFC) converter and a Proportional Integral (PI) controller. To attain the goals, the subsequent tasks are proficient: a novel Bridgeless PFC converter is developed to improve power factor correction and power quality; a PI controller is exploited to control output voltage with reduced implementation and maintenance costs and a Pulse Width Modulation (PWM) generator within a Hysteresis Current Controller (HCC) is deployed to enhance current protection, system stability, and fault tolerance. The system is validated using MATLAB/Simulink-based simulations. The significant outcomes are the accomplishment of a high charging efficiency of 97%, improved power quality, reduced heat generation, and enhanced system control operations. The significance of obtained results is that the proposed system ensures optimized EV battery charging with increased reliability, reduced implementation costs, and robust fault tolerance, contributing to the development of effective EV charging infrastructure.
