1. A power converter that directly converts polyphase AC power to AC power, the power converter comprising:

  • a converter circuit including a plurality of switching elements that are connected to each phase of the polyphase AC power to enable switching for turning on current-carrying bidirectionally; and

    at least three condensers connected to the converter circuit,wherein;

    the plurality of switching elements are adjacently arranged in such a manner that respective input terminals of switching elements of the plurality of switching elements form a first line in a first arrangement direction and respective output terminals of said switching elements of the plurality of switching elements form another line in parallel with the first line;

    the three condensers are respectively placed at apexes of a triangle on a plane that is above and in parallel with a part-mounting surface on which the plurality of switching elements are actually mounted; and

    two of the three condensers are adjacently placed and arranged along the first arrangement direction and the remaining one of the three condensers is arranged outside the two condensers with respect to the position of the output terminals.
