ABSTRACT:
A first circuit means, which serves to cause reverse flow of a first pulse current of a large rate of rising and a narrow pulse width from cathode to gate of a gate turn-off thyristor in synchronism with the instant when turning off this thyristor, and a second circuit means, which serves to caus reverse flow of a second pulse current of a smaller rate of rising and a wider pulse width than the aforesaid first pulse current in superimposition thereupon from cathode to gate in synchronism with the turn-off instant, are provided.
