POWER CONVERTER

摘要

A power converter is provided for direct conversion of multi-phase AC power to AC power. The power converter includes a conversion circuit, a plurality of input lines and a plurality of capacitors. The conversion circuit has first and second switching elements that are configured to be connected to the phases of the multi-phase AC power for bidirectional switching of energizing current. The input lines are connected to the conversion circuit. The capacitors are connected to the conversion circuit. The first and second switching elements are arranged such that paired input terminals line up in a row with the paired input terminals to an outside, and paired output terminals to an inside. The input lines extend in a direction in which the paired input terminals line up, and extend from one of the input terminals to another of the input terminals.
