Abstract

PURPOSE:To improve a delay of rise for the gate current, by flowing the current to the reactor previously and prior to a turn-off. CONSTITUTION:Before turning off the gate turn-off thyristor (GTO) 1 is turned off, the swiching elemet 5 is turned on to flow the current similar to the off-gate current to the reactor 4 of the gate circuit. Then the element 5 is turned off, and thus the sum voltage of the voltage of the turn-off gate power source and the voltage induced by the reactor 4 is applied to the thyristor 6. As a result, the thyristor 6 conducts by an anode fire, and GTO1 is turned off. In such case, the current is flowed to the reactor 4 before turn-off of GTO1. Accordingly a quick rise is secured for the gate current IG with a short accumulation time tstg.
