摘　　要：20MVarStatCom装置采用基于GTO的四重化电压型逆变器并采用他励启动方式启动。本文给出了装置他励启动时装置损耗的计算及 2 0 0 0V直流输出、80kW的他励启动整流器的设计。整流器采用双重移相全桥 ,移相触发脉冲由 80C1 96单片机产生。The independent excited start up and fourfold voltage fed inverter based on GTO are employed for a ±20MVAR StatCom.The calculation of loss for auxiliary excited strt up and the design of a 2000V/80kW start up recitfier are presented in this paper.The rectifier employes the 2 stage phase shifted SCR controlled rectifier.The SCR gating pulses are generated by a 80C196 single chip microprocessor based circuit.
