摘要: 为使三相桥式整流器实现节能运行,提出了一种节能型三相桥式零电流开关整流器拓扑结构,在各相桥臂上的辅助谐振电路处于工作状态时,整流器的开关器件能完成零电流软关断.三相桥式整流器通常以绝缘栅双极型晶体管(Insulated Gate Bipolar Transistor,IGBT)作为开关器件,实现零电流软关断能消除IGBT拖尾电流产生的关断损耗.分析了电路工作过程,在三相3kW样机上的实验结果表明开关器件实现了零电流软切换.因此,该拓扑结构可实现以IGBT作为开关器件的三相桥式整流器的节能运行.

Abstract: In order to achieve energy-saving operation of three-phase bridge rectifier, the topology of an energy-saving three-phase bridge zero-current switching rectifier is proposed. The switching devices of the rectifier can achieve zero-current turn off when the auxiliary resonant circuit on the bridge arm of each phase is in the working state. Three-phase bridge rectifier usually uses insulated gate bipolar transistor (IGBT) as switching devices and the realization of zero-current turn off can eliminate the switching loss caused by tail current of IGBT. The working process of the circuit is analyzed. The experimental results on a three-phase 3kW prototype show that the switching devices achieve zero-current soft-switching. Therefore, this topology can achieve the energy-saving operation of three-phase bridge rectifier which uses IGBT as switching devices.

Key words: energy-saving, rectifier, auxiliary circuit, zero-current turn off, tail current
