Abstract
A drive device is a drive device for driving a first switching element. The drive device includes a protection switch. The protection switch is provided between a first terminal and a third terminal of the first switching element, turned off when a voltage of the third terminal is a second threshold or more, and turned on when the voltage of the third terminal is less than the second threshold. A potential difference between the first terminal and the third terminal is less than a first threshold when the protection switch is on.
