Abstract
A drive device that drives a semiconductor switching device includes a capacitor, an output selection unit that selects whether or not to supply a charge of the capacitor to a conduction control terminal of the semiconductor switching device, and a charge consumption unit that supplies the charge of the capacitor to a portion other than the conduction control terminal, thereby consuming the charge of the capacitor.
