Claim 0:
1. A gate driver system, comprising:
a transistor configured to be driven between switching states;
a gate driver circuit coupled to a gate terminal of the transistor and configured to control a gate voltage at the gate terminal in order to drive the transistor between the switching states, wherein the gate driver circuit is configured to generate a gate control signal that controls the gate voltage during each of a plurality of turn-off switching events to turn off the transistor, wherein the transistor is configured to be turned off according to a desaturation time during each of the plurality of turn-off switching events;
a measurement circuit configured to measure a transistor parameter indicative of a voltage slew rate of the transistor for a first turn-off switching event during which the transistor is transitioned from an on state to an off state; and
a control circuit configured to receive the measured transistor parameter and regulate a duration of the desaturation time based on the measured transistor parameter.
