A drive circuit for an insulated gate device includes a constant current source generating a constant current, and a switching circuit, wherein a gate of the insulated gate device is connected to a power supply potential side via the constant current source at the time of turn-on and to a ground potential side at the time of turn-off. Whereby a drive circuit for the insulated gate device can be reduced loss at the time of turn-on and reduced temperature dependency of noise. |
