description A drive circuit drives a switch that has first and second terminals and a control terminal. The drive circuit includes a discharge path, a capacitor, an AC suppressor and a DC voltage generator. The discharge path connects the control terminal and the second terminal. The capacitor has a high-potential terminal connected to the second terminal side and a low-potential terminal connected to the control terminal side. The AC suppressor has a first end connected to a part of the discharge path between the high-potential terminal the second terminal. The DC voltage generator has a connection terminal connected to a second end of the AC suppressor. The DC voltage generator regulates electric current flowing between the connection terminal and the AC suppressor so as to keep the potential of the part of the discharge path between the high-potential terminal and the second terminal higher than the potential of the low-potential terminal.
