<p>A method for turning off higher anode currents in a GTO device (12-18) without the use of a snubber circuit and a gate inductor includes applying (by closing a switch (S2) a reverse bias voltage (V3) across the gate-cathode junction (12, 13) that is greater than the avalanche voltage, maintaining the reverse bias voltage (V3) until the anode current (I) is substantially interrupted, and then removing (by opening switch S2) the reverse bias voltage (V3) in sufficient time to prevent undue heating within the thyristor (12-18). A circuit for carrying out the method is also disclosed.</p> |
