Power conversion device with reduced wiring distance
Provided is a power converter 3 that directly converts polyphase AC power to AC power. A converter circuit has a plurality of switching elements 311, 313, 315, 312, 314 and 316 which are connected to each phase R, S or T of the polyphase AC power to enable switching for turning on current-carrying bidirectionally. At least three condensers 821 to 826 are provided between phases of the converter circuit. The three condensers are respectively placed at apexes of a triangle on a plane that is in parallel with a part-mounting surface on which the switching elements are actually mounted. The wiring distance between the condensers and the switching elements can be shortened.
