Abstract
A driving circuit for driving a switch element, which includes a control terminal, a first power terminal and a second power terminal. The second power terminal receives a first voltage. The driving circuit includes a switching circuit, a first unidirectional switch and a first capacitor. The switching circuit receives a first signal. The switching circuit is electrically connected with a first voltage terminal and a ground terminal. The first voltage terminal receives a second voltage. A voltage at the output terminal is switched between the second voltage and a ground voltage. A first terminal of the first unidirectional switch receives a third voltage. A first terminal of the first capacitor is connected with the output terminal of the switching circuit. A second terminal of the first capacitor is connected with a second terminal of the first unidirectional switch and the control terminal of the first switch element.
