Abstract:
1. A power converter, comprising: a first semiconductor module that comprises a plurality of power semiconductor elements to convert DC power to AC power; a second semiconductor module that comprises a plurality of power semiconductor elements to convert DC power to AC power; a capacitor for smoothing the DC power; capacitor terminals that transmit the DC power to the first semiconductor module and the second semiconductor module; and a passage forming body that is constructed of a thermally conductive member and forms a passage through which coolant flows; wherein: the first semiconductor module and the second semiconductor module are disposed side-by-side with a gap therebetween, at one side of the passage forming body; the capacitor is disposed at another side of the passage forming body, opposite to the first semiconductor module and the second semiconductor module; a through hole that connects between a space in which the first semiconductor module and the second semiconductor module are disposed and a space in which the capacitor is disposed is formed in the passage forming body, with the through hole being located at a position facing the gap; a DC terminal of the first semiconductor module is positioned at a side of the first semiconductor module closest to the through hole; a DC terminal of the second semiconductor module is positioned at a side of the second semiconductor module closest to the through hole; and the capacitor terminals pass through the through hole so as to electrically connect the capacitor and the first and second semiconductors.
