Patent ID: 8599554

Claim:
A power converter installed in a casing attached beneath the floor of an electric vehicle, the power converter comprising a capacitor unit and a power semiconductor module housed in a hermetically sealed part of the casing closed by a cover for closing an access port, and a cooler installed in an exposed part of the casing, the cooler cooling heat generated from the power semiconductor module, the power converter comprising: a bus bar that electrically connects the power semiconductor module and the capacitor unit; a conductive bar that electrically connects the capacitor unit and the bus bar; and a bolt inserted from a side of the access port through the bus bar toward the power semiconductor module to be installed between the capacitor unit and the bus bar, wherein the conductive bar is drawn from an upper surface of the capacitor unit, extends toward the bus bar by a distance corresponding to a sum of a length from a part from which the capacitor unit is drawn to a surface of the capacitor unit closer to the bolt and a height of a head of the bolt, and is bent into a crank.
