<P>PROBLEM TO BE SOLVED: To provide an inverter with improved conversion efficiency, reduced manufacturing cost, and suppressed leakage current. <P>SOLUTION: An inverter 3 includes a switch circuit 31 that converts DC power and outputs an AC voltage between a first output terminal A and a second output terminal B. The switch circuit 31 includes: a first switch branch 312 having a first switch element S1, a second switch element S2, and a third switch element S3; a second switch branch 313 having a fourth switch element S4, a fifth switch element S5, and a sixth switch element S6; a first freewheeling unit 310 connected to the second output terminal B and providing a freewheeling path between the first switch element S1 and the second switch element S2; and a second freewheeling unit 311 connected to the first output terminal A and providing a freewheeling path among the first output terminal A, the fourth switch element S4, and the fifth switch element S5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
