Abstract: An exemplary gate drive circuit and method are disclosed for controlling a gate-controlled component, the gate drive circuit having a PI controller adapted to receive an input reference signal and to control a gate voltage of the gate-controlled component. The gate drive circuit can include a first feedback loop for the PI controller, the first feedback loop having a first gain (kv), a second feedback loop for the PI controller, the second feedback loop having a second gain (ki), and a clipping circuit adapted to modify a feedback signal in the second feedback loop during turn-on of the gate-controlled component when the time derivative of the collector current is negative. The first feedback loop can include a first blanking circuit adapted to cut the feedback loop when the gate-controlled component is in a blocking state.
