サイリスタのゲート回路。[Claims for Utility Model Registration] A first switching element is connected in series to a first DC power source and a capacitor is connected in parallel, and the switching element is turned on by an ON command to discharge the charge in the capacitor. As a result, the on-gate circuit that supplies the on-gate current to the gate turn-off thyristor is connected in parallel to this on-gate circuit, and the off command turns on the second switching element, through which the second DC power source supplies the above-mentioned and an off-gate circuit that supplies an off-gate current to a gate turn-off thyristor, from one of the connection points between the on-gate circuit and the off-gate circuit to the other connection point through the capacitor and the first switching element. A gate circuit for a gate turn-off thyristor, characterized in that a non-linear circuit section is provided in the line from the second DC power supply of the off-gate circuit to the first switching element of the on-gate circuit so as to limit the current flowing into the first switching element of the on-gate circuit. .
