摘　　要：集成门极换流晶闸管(IGCT)比GTO和HV-IGBT有更多的优势,被广泛应用于中压大功率传动系统中。在分析了中点钳位三电平逆变器拓扑结构和IGCT结构的基础上,讨论了IGCT逆变器缓冲电路的特点。以仿真的手段对比2种缓冲电路,对缓冲电路的不足提出了解决方案。The integrated gate commutated thyristor(IGCT)is widely used in medium voltage high power drive system,which has more advantages than GTO or HV-IGBT.Based on the characters of the NPC(neutral point clamp)three-level inverter and structure of IGCT,the character of the snubber circuit used in inverter with IGCTs was discussed.The two operational principle of snubber circuits used in typical products were compared by simulation,and then the solution of the shortage of snubber circuit was presented.

关 键 词：集成门极换流晶闸管 三电平 中点钳位 缓冲电路
