Abstract:
1. A driving circuit that drives at least one switching element connected to a main current circuit, said driving circuit comprising: a driving portion applying on/off-voltage to a gate of said at least one switching element; a common inductor disposed in an interconnection part commonly connected to said driving portion and a source side of said at least one switching element in a loop formed of said main current circuit and said at least one switching element; and at least one capacitor electrically connected between said gate side and said source side on said driving portion side with respect to said common inductor, regardless of turning on/off of said at least one switching element, wherein with turning off the switching element, a driving inductance is supplied with current discharged by the capacitor to apply a negative feedback voltage of the common inductor between said gate side and said source side.
