摘要：

In this paper a new zero voltage switching current-fed push-pull converter with an active clamp circuit is proposed The active clamp circuit not only absorbs the voltage surge across switches at turn off instance, but also provides soft switching condition for all the semiconductor elements. Implementation of control circuit is very simple since the converter is PWM controlled and the auxiliary switches turn on are complementary with respect to main,switches. In this paper the proposed converter operating modes are analyzed and simulation results are presented To verify the converter operation a 200W laboratory prototype operating at 100 kHz is implemented and the experimental results confirm the theoretical analysis.
