Abstract :
A ZVS-PWM full-bridge power converter using active current clamping with synchronous rectifiers is presented. A high performance DC/DC converter can be constructed using the proposed topology because of ZVS-PWM operation and convenience of utilizing synchronous rectifiers. In experiments, a high efficiency of 88% including 2.5% of improvement is achieved and the low noise characteristic is verified in a 400 W DC/DC power converter with 10 V output for high power density board-mounted power modules
