Abstract
Disclosed is a DC-AC converter including a switch circuit for converting the DC power to output an AC voltage between a first output terminal and a second output terminal. The switch circuit includes a first switch branch having a first switch element and a second switch element; a second switch branch having a third switch element, a fourth switch element, and a fifth switch element; and a sixth switch element having one end connected between the third switch element and the fourth switch element and the other end connected between the first switch element and the second switch element. The first switch element, the second switch element, the third switch element, the fourth switch element, the fifth switch element, and the sixth switch element are configured to turn on/off to enhance the conversion efficiency of the DC-AC converter and subdue the occurrence of leak current in the DC-AC converter.
