The positive and negative DC voltage input conductive plates 10 and 20 and the AC output conductive plates 70, 80 and 90 are adjacent to each other in parallel.
FIG. 10 shows a main part of this configuration as an electric circuit. Now, in the mode in which the conduction control elements 31A and 41B are in the conduction state and the other conduction control elements are in the non-conduction state,

The smaller the gap is, the larger the canceling magnetic flux is, and accordingly, the wiring inductance between the conductive lines A and B is reduced. Since the two currents Ia and Ib in the conduction mode are also adjacent to each other, the magnetic fluxes induced by the two currents Ia and Ib cancel each other, and as a result, the wiring inductance of the current path is reduced.
