Abstract

See full text

A gate driver system includes a gate driver circuit coupled to a gate terminal of a transistor and configured to control a gate voltage to generate an on-current during a plurality of turn-on switching events to turn on the transistor. The gate driver circuit includes a first driver configured to source a first portion of the on-current to the gate terminal to charge a first portion of the gate voltage, and a second driver configured to, during a boost interval, source a second portion of the on-current to the gate terminal to charge a second portion of the gate voltage. A control circuit measures a transistor parameter representative of a reverse recovery current of the transistor for a turn-on switching event during which the transistor is transitioned to an on state and controls the first driver and controls the second driver based on the measured transistor parameter.
