Abstract

Provided is a power converter which enables improved performance, and allows each of a semiconductor module and a capacitor module to be more reliably cooled. In a power converter, a capacitor module includes a capacitor module main body facing a cooling surface of a cooler, while being apart from the cooling surface, and a heat conductive member provided in the capacitor module main body. The capacitor module main body is connected to a semiconductor module via an N-side bus bar and a P-side bus bar. A heat radiation portion of the heat conductive member is thermally connected to the cooling surface at a position more distant from the semiconductor module than an end portion of the capacitor module main body which is closer to the semiconductor module.
