Abstract
Obtained is a power conversion device that suppresses size increase thereof while improving cooling performance for a smoothing capacitor. The power conversion device includes: a cooler having a cooling surface on an outer side thereof and a flow path on an inner side thereof, the flow path being formed such that a coolant flows through the flow path; and a smoothing capacitor fixed to the cooler, the smoothing capacitor being thermally connected to the cooling surface with a heat transfer member therebetween and configured to smooth DC power. A thickness of the heat transfer member between the smoothing capacitor and a portion, of the cooling surface, to which the smoothing capacitor is thermally connected is set to be smaller than a wall thickness of the cooler between the flow path and the portion, of the cooling surface, to which the smoothing capacitor is thermally connected.
