高压集成门极换流晶闸管

The high-voltage integrated gate commutated thyristor (IGCT, reverse-blocking type) is a suitable device for hybrid line-commutated converters to resist commutation failures. During the turn-on process, a voltage plateau is observed under a high the current rise rate di/dt up to kA/μs. In order to decipher the mechanism and the potential risk of this phenomenon, this article focuses on the micropr...
