Abstract

This paper proposes a high-efficiency soft-switching pulse-width modulated (PWM) full-bridge (FB) dc-dc converter for the on-board battery charger of electric vehicles (EVs). Asymmetrical PWM (APWM) FB converter is proposed with zero-voltage switching (ZVS) of the power switches and zero-current switching (ZCS) of an output diode. Switching losses can be reduced by achieving ZVS and ZCS. Conduction losses are also reduced by eliminating circulating currents. Compared to the conventional phase-shift modulated (PSM) FB converter, the proposed converter has less component counts and reduces power losses, improving the power efficiency. As a result, a high efficiency can be achieved for the on-board battery charger of EVs. The performance of the proposed converter is evaluated by experimental results for an 1.0 kW prototype circuit.
