Abstract:
Exemplary embodiments are directed to a gate drive circuit and a method for controlling a gate-controlled component. The gate drive circuit includes a PI controller that receives an input reference signal (vref,d/dt) controls a gate voltage of the gate-controlled component. The gate drive circuit also includes a first feedback loop for the PI controller adapted to provide feedback from a time derivative of a collector-to-emitter voltage (vCE) of the controlled component. The first feedback loop has a first gain (kv). A second is provided in the gate drive circuit feedback loop for the PI controller that provides feedback from the time derivative of the collector current (iC) of the controlled component. The second feedback loop has second gain (ki) and includes a clipping circuit that modifies the feedback signal in the second feedback loop during turn-on of the controlled component when the time derivative of the collector current is negative.
