一种抑制电流丝并提高di/dt能力的逆阻型晶闸管脉宽可调触发方法

In this article, to suppress the current filamentation and improve di/dt capability, a pulsewidth adjustable trigger method based on Marx generator for reverse blocking diode thyristor (RBDT) is proposed. The importance of trigger voltage pulsewidth for RBDT is first illustrated. The influence of the width of the voltage trigger pulse on RBDT is simulated in TCAD and verified by experiments. It is...
