Abstract:
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.

Claim (Index 1):
A drive circuit that drives a switch,\n the switch having a first terminal, a second terminal and a control terminal, the switch being configured to be turned to an ON state when a potential difference of the control terminal with respect to the second terminal becomes higher than or equal to an ON threshold voltage and turned to an OFF state when the potential difference becomes lower than an OFF threshold voltage, the switch allowing electric current to flow from the first terminal to the second terminal in the ON state and blocking electric current from flowing from the first terminal to the second terminal in the OFF state, the drive circuit comprising: a discharge path provided to connect the control terminal and the second terminal of the switch and discharge electric charge from the control terminal; a capacitor provided in the discharge path and having a high-potential terminal connected to the second terminal side and a low-potential terminal connected to the control terminal side; an AC suppressor configured to suppress an AC component of electric current, the AC suppressor having a first end and a second end, the first end being connected to a part of the discharge path between the high-potential terminal of the capacitor and the second terminal of the switch; and a DC voltage generator that generates a reference DC voltage, the DC voltage generator having a connection terminal connected to the second end of the AC suppressor, the DC voltage generator being configured to regulate electric current flowing between the connection terminal and the AC suppressor so as to keep a potential of the part of the discharge path between the high-potential terminal of the capacitor and the second terminal of the switch higher than a potential of the low-potential terminal of the capacitor.
