摘　　要：本文针对现有“电力电子技术”相关教材中存在的对双向变换器的分析不完善和各知识点之间缺乏联系等问题,探析了双向Buck/Boost变换器的拓扑生成原理,并且详细分析了变换器运行于电感电流过零模式下实现零电压开关的具体过程,并推导出了软开关的实现条件。本文有助于学生理解并加深双向变换器与基本Buck和Boost变换器之间的联系和差别,并了解软开关技术在基本变换器中的应用,具有一定的教学指导意义。The analysis on the bidirectional converter is insufficient in Power Electronics course.The principle of topology generation for bidirectional Buck/Boost converters is analyzed in detail.The inductor current runs in the zero-crossing mode to achieve the soft switching,and the implementation conditions of the zero-voltage-switch are deduced.This article helps students understand the connection and difference between bidirectional converters and basic Buck or Boost converters,and realize the application of soft-switching technology in basic converters.It has certain teaching guidance significance.
