Abstract
A gate circuit for a thyristor is disclosed which includes a power supply for feeding gate-on current through a gate and cathode of the thyristor, a switching circuit connected in series with the power supply to turn the gate-on current on or off, and a diode connected between a gate ignition signal input terminal of said switching circuit and the anode of said thyristor with the cathode of said diode being coupled to said anode of said thyristor and the anode of said diode coupled to said switching circuit.
