Provided is a power converter 3 that directly converts polyphase AC power to AC power. A converter circuit has a plurality of first switching elements 311, 313 and 315 and a plurality of second switching elements 312, 314 and 316, both of which are connected to each phase R, S or T of the polyphase AC power to enable switching for turning on current-carrying bidirectionally. Condensers 821 to 826 are provided between phases. Input terminals of the first switching elements and those of the second switching elements are arranged to form respective lines. Some of the plurality of condensers 821 and 822 are arranged to be angled relative to the arrangement direction of the terminals.
