DRIVING CIRCUIT AND SEMICONDUCTOR DEVICE

摘要

A driving circuit of the present invention drives a switching element connected to a main current circuit. The driving circuit includes a driving potion applying on/off-voltage to a gate of the switching element, a common inductor disposed in an interconnection part commonly connected to the driving circuit and a source side of the switching element in a loop formed of the main current circuit and the switching element, and a capacitor connected between the gate side and the source side on the driving portion side with respect to the common inductor.
