Abstract

This paper presents the design and analysis of a Sheppard–Taylor converter for efficient AC–DC power conversion in electric vehicle (EV) charging applications. The proposed system integrates power factor correction (PFC) to improve input power quality and reduce harmonic distortion. A high-frequency transformer is employed to achieve electrical isolation and compact design. The converter operates with a closed-loop control strategy to maintain stable output voltage under varying load conditions. Pulse Width Modulation (PWM) is used to control the switching devices, ensuring reduced switching losses and improved efficiency. The system is modeled and simulated using MATLAB/Simulink to evaluate its performance. Simulation results demonstrate improved power factor, regulated DC output, and enhanced overall efficiency, making the proposed converter suitable for modern EV charging and renewable energy applications
