Abstract
In a gate driving circuit, when a driving target device is turned on, an auxiliary driving element is turned on to form a closed circuit comprising a DC power source, a reactor, an auxiliary driving element and an OFF-driving element, and make reactor current flow in the direction from a power source intermediate point to an output point in advance. Just before the driving target device is turned on, the OFF-driving element is turned off to form a resonance circuit comprising the reactor, the auxiliary driving element and the gate capacitance, and make gate current (reactor current) flow so that the gate capacitance is charged by using resonance phenomenon of the resonance circuit.
