Web26 mei 2013 · Measurements show that the IGBT is able to clamp the collector-emitter voltage to a certain value at short-circuit turn-off despite a very low gate turn-off resistor … WebWhen the gate driver produces a negative voltage to turn-off the IGBT, a negative current flows in the gate circuit. Should active clamping occurs, gate current is modified and becomes positive. Gate-emitter capacitance recovers charge and gate to emitter voltage increases : the IGBT is in a conduction state in the linear region.
