Patent ID: 7978468

Claim:
A power converter, comprising: a semiconductor module that includes a plurality of power semiconductor elements and converts DC power to AC power; a capacitor for smoothing the DC power; a DC-side connecting conductor that electrically connects the semiconductor module and the capacitor; and a casing that houses the semiconductor module, the capacitor and the DC-side connecting conductor, wherein: the casing includes a first upper case that has an opening, a lower case that closes the opening of the first upper case, and a second base held by the first upper case; the semiconductor module is fixed to the second base in a space between the first upper case and the second base via a first base that forms a coolant passage; the capacitor is disposed in a space between the second base and the lower case; an opening is formed in the second base at a position facing a space between a side of the first base and an inner wall of the first upper case; and the DC-side connecting conductor passes through the opening of the second base and extends through the space between the side of the first base and the inner wall of the first upper case so as to connect the semiconductor module and the capacitor.
