Abstract
An inverter including a switch circuit for converting a DC power to output an AC voltage between a first output terminal and a second output terminal is provided. The switch circuit includes a first switch branch having a first switch element, a second switch element, and a third switch element; a second switch branch having a fourth switch element, a fifth switch element, and a sixth switch element; a first freewheeling unit connected to the first switch element, the second switch element, and the second output terminal for providing a freewheeling path between the second output terminal and the first switch element and the second switch element; and a second freewheeling unit connected to the fourth switch element and the fifth switch element and the first output terminal for providing a freewheeling path between the first output terminal and the fourth switch element and the fifth switch element.
