ABSTRACT:
A parallel connected gate turn-off thyristor device including an additional short circuiting conductor connected between the gate terminals of the respective gate turn-off thyristors so as to bypass a part of the turn-on and turn-off gate currents of one gate turn-off thyristor to other gate turn-off thyristors to increase the turn-on and turn-off gate currents of the other gate turn-off thyristors thereby hastening the turn-on and turn-off operations of the other gate turn-off thyristors.
