A Study on Efficiency and Characteristic of Zero Voltage Switched Half-Bridge Converter and Forward Converter

영전압 스위칭 하프브리지 컨버터와 포워드 컨버터의 효율 및 특성에 관한 연구

In this paper, zero voltage switched half bridge converter and an active-clamped, zero voltage switched forward converter equipped with self-driven synchronous rectifier is designed and investigated for high efficiency BC-DC converter. A synchronous rectifier is has a lower conduction power loss than shottky diode rectifier. The purpose of this paper is to investigate the effect of parasitic inductance in a synchronous rectifier of DC-DC converters and examine overall efficiency of zero voltage switched DC-DC converters.
