Abstract :
The paper proposes a novel boost battery charger in which a full-bridge zero-voltage and zero-current switching (ZVZCS) PWM DC/DC converter is included. For the sake of attaining output voltage up to 600 V, a dual-full-bridge rectifier is designed to reduce high voltage stress and solve the problem of dynamic voltage sharing of the diodes. A phase shift PWM controller UC3895 is used as voltage and current regulator, and a PIC16F716 based controller is adopted to perform automatic mode switching. Advantages such as intelligent control and no additional active switch and snubber make the proposed charger efficient and cost effective. Theoretical analysis and experimental results both confirm the validity of the proposed design
