摘要
为了降低开关损耗,提高变换器的效率,详细分析了一种基于ZCT软开关技术的三相PWM整流器,并研制了一台10 kVA ZCT软开关的PWM整流器工程样机,实现了电力电子开关器件在PWM整流器工作时的零电流开通与关断。
In order to reduce switching loss and enhance efficiency of converter, the article detailed analyses a ZCT soft switching based on three-phase PWM rectifier, and developed a PWM rectifier engineering prototype of 100 kVA ZCT soft switching, which realizes zero current turning-on and zero voltage turning-off of power electronic switching devices when working on the PWM rectifier.
