Abstract: The present invention discloses a System and A method of driving a power switch in combination with regulated DI/DY and/or DV/DT. In accordance with an embodiment, a method of driving a switching transistor includes the steps of: driving the switching transistor with a gate drive signal; measuring at least one of a derivative of a load path voltage and a derivative of a load path current of the switching transistor; measuring a derivative of the gate drive signal; forming an error signal based on a reference signal, a measured derivative of the gate drive signal, and at least one of the measured derivative of the load path voltage of the switching transistor or the measured derivative of the load path current of the switching transistor; and forming the gate drive signal, where forming thegate drive signal includes processing the error signal using a dynamic controller.
