ZVZCS移相全橋變換器的拓撲綜述

摘要：本文總結了以往一些ZVZCS移相全橋變換器的拓撲，在實現主電流復位的常用方法的基礎上，簡要介紹了最近一些新穎的ZVZCS移相全橋變換器拓撲，分析了工作原理，并給出了主要波形圖。 敘詞：ZVZCS，移相全橋，PWM變換器 Abstract：This paper concludes the topologies of ZVZCS PS Full-bridge converters in the past, simply introduces some novel ones on the basic of making the primary current zero , analogies their operating principals and the primary waveforms are presented. Keyword：ZCZVS, shift-phase full-bridge, PWM converter
