1. A power converter, comprising:

  • a power semiconductor module configured to convert DC power into AC power;

    a control circuit board configured to control the power semiconductor module; and

    a case configured to store the power semiconductor module and the control circuit board,wherein the power semiconductor module comprises a switching element and a metal module case forming a storage space for storing the switching element,the case comprises a resin case configured to store the power semiconductor module, a metal case configured to store the control circuit board, and a metal base disposed so as to separate a storage space of the resin case and a storage space of the metal case,the resin case forms a refrigerant flow channel in which a refrigerant flows to cool the power semiconductor module,the power semiconductor module is disposed such that the module case is projected in the refrigerant flow channel,the metal base forms a first opening,the power semiconductor module is disposed such that the storage space of the module case and the storage space of the metal case are connected via the first opening of the metal base, andthe metal case, the metal base, and the module case are electrically connected.
