Abstract
An electric power conversion device includes: a cooler that includes a flow path through which a refrigerant flows, a first surface, and a second surface opposite to the first surface in a thickness direction; and multiple power modules that include a semiconductor device configuring an upper-lower arm circuit, and a capacitor connected to the upper-lower arm circuit in parallel. The capacitor and the semiconductor device are arranged in the thickness direction. The multiple power modules are placed on both of the first surface and the second surface of the cooler.
