ABSTRACT:
A gate circuit for gate turn-off thyristors is disclosed which includes a turn-on circuit formed of a series combination of a turn-on power source and an NPN transistor and a turn-off circuit formed of a series combination of a turn-off power source and a thyristor, and in which a PNP transistor is provided between the anode and gate of the thyristor in such a manner that the base of the NPN transistor and the base of the PNP transistor are connected to each other and a junction of these bases receives a control signal for turning on or off a gate turn-off thyristor.
