1. A power converter for a vehicle, wherein a series circuit of a positive-side semiconductor switching arm and a negative-side semiconductor switching arm which are formed of switching semiconductor elements is connected between a positive potential side and a negative potential side of a DC voltage supply;

  • an output terminal is led out from a series joint of the two sets of semiconductor switching arms;

    an anode of the positive-side semiconductor switching arm is connected to the positive potential side of the DC voltage supply, while a cathode of the negative-side semiconductor switching arm is connected to the negative potential side of the DC voltage supply;

    the series circuit of the two sets of semiconductor switching arms is used as one phase component of the power converter;

    all the switching semiconductor elements which form the semiconductor switching arms are arranged on the same plane of a cooler; and

    a cooling section of the cooler is configured of a plurality of fins so that the switching semiconductor elements may be cooled by a refrigerant which flows between the fins;

    characterized in that the switching semiconductor elements are disposed on the same plane of the cooler so that longitudinal directions of the semiconductor switching arms may become perpendicular to a flowing direction of the refrigerant.
