摘　　要：应用于高压环境的电气系统需要能充当断路器的高速开关,以便于在故障发生时于尽可能短的时间内切除主电源。针对这种需求,串联IGBT是一个理想的选择;而串联IGBT的均压问题需要深入研究。介绍了一种有源门极驱动触发时间补偿法以实现各IGBT的均压,并在1 500 V/10 A的电路环境下进行了3个IGBT模块的串联实验。实验结果表明该方法能有效地改善串联IGBT的均压效果。The electric system on high voltage condition requires fast switches as circuit breakers to cut off the power supply as soon as possible when failure occurs.Series connected IGBTs is an idea choice in this case.The main issue of series connected IGBTs is the voltage balance.An active gate trigger time compensation method was presented.The test was worked on a set of3series connected IGBTs where the environment was1500V/10A.The test result proves that the method can improve the voltage balance of IGBTs.
