Abstract:
A gate drive circuit including a drive-on element that applies an on-state voltage to a gate of a drive target semiconductor element and a drive-off element that applies an off-state voltage to the gate is such that a recovery switch, a reactor, and a capacitor are connected in series between output terminals of the gate drive circuit as a recovery circuit that can recover a charge accumulated in input capacitance of the drive target semiconductor element when turning on, and the drive-on element, the drive-off element, and the recovery switch are controlled by a control circuit, whereby power consumption of the gate drive circuit is reduced.

Claim (Index 22):
The gate drive circuit according to  claim 17 , wherein, when starting up the gate drive circuit, the positive electrode side driver switch and the positive electrode side recovery switch are simultaneously turned on for a certain period, the negative electrode side driver switch and the negative electrode side recovery switch are turned off, and an initial charging is carried out from the positive electrode side gate power supply to the positive electrode side capacitor.
