Environment Friendly EV Charger with Isolated HBC

Abstract

A power quality improved bridgeless power factor corrected converter (BPFCC) based battery charger is designed, modeled and its performance has been analyzed in this paper. Bridgeless operation of power factor corrected converter ensures high efficiency and low conduction losses. The use of isolated half bridge converter (HBC) improves dynamic response in all operating condition. To maintain the battery current, current controller along with voltage controller are being used in synchronization. The proposed configuration draws a sinusoidal input current and almost unity PF which is in line with standard set by international regulatory. The observed performance of verifies the design and satisfactory charging operation at all operating conditions.
