变压器副边有源箝位式ZVZCS FB PWM变换器主电路分析

Analysis and Simulation of ZVZCS FB PWM Converter by Using Secondary Active Clamp

分析了一种变压器副边采用有源箝位的 ZVZCS全桥移相式 PWM变换器的主电路拓扑结构 ,该变换器适合于高电压、大功率 ( >1 0 k W)场合。文中利用强大的电力电子仿真软件 SABER对主电路参数的选择进行了验证 ,取得了与分析一致的结果。

The operation principle of Zero Voltage and Zero Current Switching Full Bridge PWM converter by using secondary active clamp is proposed in this paper. This converter is attractive for high-voltage and high-power applications. In addition its feasibility is verified by SABER simulation.
