ABSTRACT:
A capacitor charged with a voltage across anode and cathode of a thyristor after the voltage division and rectification is connected across gate and cathode of the thyristor through a switch while a diode with or without a series reactor is connected across the anode and gate through the same switch. Alternatively a primary winding of an insulating transformer may be connected across the anode and cathode and its secondary winding is operative to charge the capacitor through diodes. The switch is preferably a light switch.
