ABSTRACT:
An electrical circuit comprising at least one thyristor having an anode, cathode and gate; an ignition circuit for applying an ignition signal between the gate and cathode of the thyristor when turning on the thyristor; a turn-off circuit for turning off the thyristor which applies a reverse voltage between the anode and cathode of the thyristor when turning off the thyristor and which comprises an inverse bias circuit; said inverse bias circuit comprising a first path across the gate and cathode of the thyristor and a second path acrosss the gate and anode of the thyristor; and said bias circuit applying a reverse bias voltage having opposite polarity to the ignition signal between the gate and the cathode of the thyristor.
