High Efficiency Active Clamp Forward Converter with Synchronous Switch Controlled ZVS Operation

동기 스위치 제어를 통한 영전압 동작 고효율 능동 클램프 포워드 컨버터

A new synchronous switch controlled transient current build-up zero voltage switching (TCB-ZVS) forward converter is proposed. The proposed converter is suitable for the low-voltage and high-current applications. The features of the proposed converter are low conduction loss of magnetizing current, no additional circuit for the ZVS operation, high efficiency, high power density and low EMI noise throughout all load conditions.
