Abstract

A gate drive circuit and a method for controlling a gate-controlled component (30), the gate drive circuit comprising a PI controller (31) adapted to receive an input reference signal (v ref,d/dt ) and to control a gate voltage of the gate-controlled component. The gate drive circuit comprises a first feedback loop for the PI controller (31), the first feedback loop comprising first gain (k v ), a second feedback loop for the PI controller (31), the second feedback loop comprising second gain (k i ). The second feedback loop comprises a clipping circuit (32) adapted to modify a feedback signal in the second feedback loop during turn-on of the controlled component (30) when the time derivative of the collector current is negative and the first feedback loop comprises a first blanking circuit (101) adapted to cut the feedback loop when the controlled component is in a blocking state.
