Patent ID: 8355244

Claim:
An electric power converter comprising: a capacitor electrically connected to either a semiconductor module or a reactor that contains a semiconductor element therein; and a cooler that is in thermal contact with either the semiconductor module or the reactor; wherein, at least one of a plurality of capacitor terminals provided in the capacitor is arranged between the cooler and the capacitor, and the capacitor terminal contacts the cooler thermally in a state where the capacitor terminal is sandwiched between the cooler and the capacitor, the capacitor terminal that contacts the cooler thermally is a terminal connected to the semiconductor module or the reactor, the capacitor terminal that contacts the cooler thermally is a terminal connected to an electronic components different from the semiconductor module or the reactor, the capacitor terminal are connected to a pair of electrodes disposed in the capacitor, and at least one of the capacitor terminals thermally contact the cooler in the state of being arranged between the cooler and the capacitor at a position between a portion connected to the semiconductor module or the reactor and a portion connected to the electrodes.
