Abstract
It is an object of the present invention to provide a buffer circuit that reduces a reverse voltage applied to transistors being a complementary pair during turn-on and turn-off. A buffer circuit is a buffer circuit that turns on and turns off a switching element and includes a drive-side element that has an end connected to a base of a drive transistor and a sink-side element that has an end connected to a base of a sink transistor. The drive-side element and the sink-side element are respectively a drive-side diode and a sink-side diode, or a drive-side capacitor and a sink-side capacitor.
