摘要

本文提出了一种采用有源箝位电路的软开关反激变换器，用于回收反激变压器的泄漏能量。捕获的泄漏能量进一步用于给与输入电源串联连接的箝位电容器充电。因此，反激变换器的总电压增益被提高。该反激变换器的所有半导体开关都在软开关条件下工作，半导体二极管进行软换相。通过实验室样机的硬件实验，成功验证了该变换器的性能。

Efficient Energy Recovery and Boosting the Voltage Gain of a Soft-Switched Flyback Converter

This paper presents a new soft-switched flyback converter with an active clamp circuit, used to recover the leakage energy of the flyback transformer. The trapped leakage energy is further utilized for charging a clamping capacitor, connected in series with the input supply. Thus, overall voltage gain of the flyback converter is boosted up. All the semiconductor switches of this flyback converter are operated under soft-switching conditions and the semiconductor diodes are commutated softly. Performance of the proposed converter has been successfully verified through hardware experimentation of a laboratory prototype.
