Abstract

new topology of an improved Zero-Voltage and Zero-Current Soft–Switched Full-Bridge Phase-Shifted PWM (ZVZCS-FB-PWM) DC/DC Converter for a battery charger application is analyzed and designed. To improve the conventional phase-shifted ZVS PWM converter, an auxiliary transformer and a small discrete inductor (commutation inductor) are added in the primary circuit of the power transformer. Experimental results from a 600 V/2.6 kW -70 kHz prototypes validate the design.
