초록
An active-clamp current-fed push-pull converter for the step-up application is proposed. The proposed converter is composed of active-clamp circuits and a voltage doubler rectifier. Thus, the voltage stress of the main switches is reduced and the output diodes are clamped to output voltage. Moreover, the output diodes can achieve zero current switching (ZCS) by the series resonance between resonant capacitors and leakage inductances. The prototype is designed for 350V/1.5kW with input voltage range
