<p>A power conversion device (3) that directly converts polyphase AC power to AC power. 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 aforementioned polyphase AC and can switch the flow of current between two directions. The power conversion device is also provided with a plurality of capacitors (821-826) connected to the aforementioned conversion circuit. At least one of said capacitors is provided between each pair of phases of the polyphase AC current in correspondence with the first switching elements, and at least one of the capacitors is provided between each pair of phases of the polyphase AC current in correspondence with the second switching elements. This makes it possible to reduce the wiring distance between the capacitors and the switching elements.</p> |
