Abstract

A direct parallel connection circuit of gate turn-off thyristors wherein a plurality of GTO's having different current capacities are directly connected in parallel. A turn-on gate current and a turn-off gate current are passed to the gate of each of GTO's through a resistor and a reactor, respectively so as to substantially simultaneously turn-on and turn-off GTO'S, respectively.
