Abstract:
A control circuit controls a switching element including a gate and a source corresponding to the gate. The control circuit includes an inductor, a circuit element, and a resistor. The inductor is connected between the gate and the source of the switching element. The circuit element is connected in series to the inductor between the gate and the source. The circuit element allows an electric current to flow therethrough in response to generation of electromotive force in the inductor. The resistor is connected in parallel to the inductor and the circuit element between the gate and the source.
