BATTERY CHARGER FOR ELECTRIC VEHICLES WITH MODIFIED POWER FACTOR CORRECTED BRIDGELESS CONVERTER

Abstract

This paper presents modified bridgeless single-stage converter to charge light Electric vehicle (EV) battery. The main aim is to improve the efficiency and attain the Unity Power Factor (UPF) of the bridgeless converter for battery charger. The converter has a single stage power conversion with tapped inductor boost converter. The converter is having a bridgeless configuration that minimizes the conduction losses of the input diodes. In this configuration the voltage is boosted using the converter and easily charge the EV battery. In two-stage converter the losses are more, and the configuration is bulky. In the proposed charger the conduction losses can be reduced, attain voltage gain, PF and efficiency can be improved. Hence the single stage bridgeless converter with boost converter based on tapped inductor is used to improve the above-mentioned parameters. The existing and modified system is verified using MATLAB Simulink software and the results proves the effectiveness of the charger
