WebNov 26, 2024 · For natural cooling, the anode (bolt) is attached to the aluminum radiator; the flat thyristor is made up of two Thyristors clamped by a pair of mutually insulated radiators that receive cold air cooling. The plate type is used in thyristors with rated currents larger than 200A because it effectively dissipates heat on both sides of the device. WebThe anode current (IA) is the sum of the gate current IGQ and the cathode current (IK). To turn the thyristor off the base current needs to be smaller than the IRB. In theory, if an adequate amount of reverse bias current is supplied to the gate, then the turn-off function will automatically be carried out by the GTO thyristor.
