Power converter
First Claim
1. A power converter for direct conversion of multi-phase AC power to a single phase AC power, the power converter comprising:
- a conversion circuit having a plurality of first switching elements configured to be connected to phases of the multi-phase AC power for bidirectional switching of energizing current, and a plurality of second switching elements configured to be connected to the phases of the multi-phase AC power, for bidirectional switching of energizing current; and
a plurality of output lines connected to the conversion circuit;
the first switching elements having output terminals and the second switching elements having output terminals, the output terminals of the first switching elements being linearly arranged, the output terminals of the second switching elements being linearly arranged and facing the output terminals of the first switching elements,the output lines being configured to output the single phase AC power, the output lines including a pair of first output lines including a first widely shaped bus bar connected to the output terminals of the first switching elements and a second widely shaped bus bar connected to the output terminals of the second switching elements, the first output lines extending out in one direction, and lining up in an upright direction.

Abstract
A power converter is provided for direct conversion of multi-phase AC power to AC power. The power converter includes a conversion circuit and a plurality of output lines. The conversion circuit has first and second switching elements that are configured to be connected to phases of the multi-phase AC power for bidirectional switching of energizing current. The output lines are connected to the conversion circuit. The first and second switching elements have output terminals. The output terminals of the first and second switching elements are arranged in first and second rows. The output terminals of the first and second switching elements face each other. The first output lines include two first output lines including first and second widely shaped bus bars connected to the output terminals of the first and second switching elements, respectively. The first output lines extending out in one direction, and line up in an upright direction.
