ートターンオフサイリスタの制御回路。[Claims for Utility Model Registration] A series circuit of gate turn-off thyristors connected in series in the forward direction with respect to a DC power supply, and a gate turn-off thyristor connected between the cathode of the gate turn-off thyristor at the final end of the series circuit and ground. a switching element, an on-gate circuit that supplies an on-gate current to the gate turn-off thyristor at the final end when the switching element is on, and a semiconductor element that becomes conductive when a reverse voltage of a predetermined value or higher is applied, connected in series between the DC power supply and ground. and a series circuit of semiconductor elements in which each bridge point between the adjacent semiconductor elements is connected to the gate of the gate turn-off thyristor, and when the on-gate circuit is operated, the DC power supply is connected to the semiconductor element through the semiconductor element. conducts an on-current to the gate of each of the gate turn-off thyristors and controls the switching element to turn off, thereby increasing the cathode voltage of each of the gate turn-off thyristors and drawing an anode current from the gate to the side of each of the semiconductor elements. A control circuit for a gate turn-off thyristor.
