三相隔离式全桥Boost PFC变换器的启动与电压尖峰抑制方案研究与实现

A starting and voltage spike suppression scheme is proposed and investigated in a three-phase isolated full-bridge boost power factor correction (PFC) converter with the passive flyback auxiliary circuit. In steady state, the auxiliary circuit in the PFC converter is operating as a passive clamp circuit, by which the voltage spike across primary side of the power transformer is suppressed, and the...
