Abstract
The current through the main conduction path of a gate-turn-off silicon controlled rectifier (GTO) charges a capacitor in the cathode circuit of the rectifier. The GTO is turned off by providing a discharge path for the capacitor via the cathode-to-gate electrode of the GTO. A diode in the charging path of the capacitor becomes back-biased during discharge of the capacitor, thereby preventing the load in the cathode circuit of the rectifier from bypassing any of the discharge current.
