直流断路器中并联IGBT模块的开断电流平衡增强方法

Limited by the turn-off ability of single power module, parallel connection of insulated-gate bipolar transistors (IGBTs) is essential to enable breaking ability of current in the order of tens of kA. To realize high utilization rate of parallel power modules with turn-off inconsistency in dc circuit breaker, breaking current balance enhancement method is proposed in this article. There are two ma...
