Abstract

PURPOSE: Counter bias supply voltage is increased and turn-off time is raduced by equipping clip circuit limiting the voltage between gate of gate control type thyristor and cathod within its counter withstand voltage.
CONSTITUTION: Voltage clip circuit consisted of diode D1 and condenser C1 between gate of gate control type thyristor 1 and cathode, then condenser C3 is connected between counter bias power source E1, of which terminal voltage charges condenser C1 by input constant voltage integrated circuit 6, whereby counter bias voltage E1 can be increased and turn-off is made high-speeding by clipping voltage exceeding the required value by condenser C1 charged to the voltage within counter withstand voltage between gate and catlod and diode D1, when controlling switching transistor Tr is "ON" and thyristor is turn-off.
