Abstract
A power conversion device can be miniaturized. A power conversion device includes a power module that performs switching operation, a smoothing capacitor that smooths a voltage ripple caused by the switching operation, a circuit board that controls driving of the power module, a housing that accommodates the power module and the smoothing capacitor, a first fixing member for fixing the power module to the housing, and a second fixing member for fixing the smoothing capacitor to the housing. The circuit board straddles between the power module and the smoothing capacitor, and is fixed by the first fixing member and the second fixing member.
