摘　　要：通过对基于集成门极换向晶闸管(IGCT)的大功率三电平交-直-交变流器的结构、控制系统、保护系统的研究,设计了一套7.5 MVA变流器系统。该变流器采用模块化结构设计,减小了变流器中的杂散电感。控制系统采用基于VME总线的VMIC核心系统和DSP微机控制系统。试验结果表明,该变流器达到了设计要求。Through research on topology and control system and protection system of IGCT-based large power three-level AC-DC-AC converter,a set of 7.5 MVA converter system was designed. Modulariza- tion design was adopted in the converter to reduce stray inductance. VMIC core system based on VME bus and DSP microcomputer control system were used in control system. Test results show that the con- verter has reached design requirement.
