Abstract
A driving circuit that drives a semiconductor device includes first to sixth semiconductor devices. A first state and a second state are provided in one cycle in which a voltage is applied to a control terminal of the semiconductor device. In the first state, the first semiconductor device is closed, the third and fourth semiconductor devices are opened, and when the second semiconductor device is structured to have a semiconductor switch, the semiconductor switch is closed. In the second state, the first semiconductor device is opened, and the third and fourth semiconductor devices are closed.
