비대칭 하프-브릿지 컨버터의 무부하시 전력소모 감소에 관한 연구

This paper deals with power saving technique for the asymmetrical half-bridge converter on no-load. Because of ZVS the converter has efficiency and represents low EMI characteristics. However, the ZVS operation leads to power loss under no-load condition. It is caused by conduction current through parasitic elements. A scheme of power saving at no=lead is represented and verified through experimental results for 60W sample.
