POWER CONVERSION DEVICE

摘要

A power conversion device (3) that directly converts polyphase AC power to AC power is disclosed. A conversion circuit has a plurality of first switching elements (311, 313, 315) and a plurality of second switching elements (312, 314, 316) that are connected to the phases (R, S, T) of the polyphase AC and can switch the flow of current between two directions. Output lines (331, 332) comprising a pair of bus bars are connected to the aforementioned conversion circuit. The output terminals of the first switching elements are laid out in a single line, as are the output terminals of the second switching elements. The aforementioned output lines (331, 332) are connected to said output terminals and extend straight off in one direction.
