Abstract

Disclosed is a DC-AC converter (4) including a switch circuit (41) for converting the DC power to output an AC modulating voltage (V T ) between a first output terminal (A) and a second output terminal (B). The switch circuit (41) includes a first switch branch (411) having a first switch element (S 1 ) and a second switch element (S 2 ); a second switch branch (412) having a third switch element (S 3 ), a fourth switch element (S 4 ), and a fifth switch element (S 5 ); and a sixth switch element (S 6 ) having one end connected between the third switch element (S 3 ) and the fourth switch element (S 4 ) and the other end connected between the first switch element (S 1 ) and the second switch element (S 2 ). The first switch element (S 1 ), the second switch element (S 2 ), the third switch element (S 3 ), the fourth switch element (S 4 ), the fifth switch element (S 5 ), and the sixth switch element (S 6 ) are configured to turn on/off to enhance the conversion efficiency of the DC-AC converter (4) and subdue the occurrence of leak current in the DC-AC converter (4).
