发明名称 Turn-off control circuit for a gate turn-off thyristor
摘要 A turn-off control circuit for a gate turn-off thyristor is used in a state where one end of an inductive load is connected therewith on the cathode side. The turn-off control circuit includes a first turning-off transistor, which takes-out electric current through the gate at the first stage of the turn-off operation of the gate turn-off thyristor, and a second turning-off transistor, which takes-out electric current through the gate at the second stage of the turn-off operation of the gate turn-off thyristor so as to surely effect the turn-off operation.
