Abstract

A power module for operating an electric vehicle drive may include one or more of the following: a plurality of semiconductor components; an intermediate circuit capacitor connected in parallel to the semiconductor components; a heatsink for the removal of heat generated by the semiconductor components, where the heatsink is located between the semiconductor components and the intermediate circuit capacitor; and an intermediate circuit line that electrically connects the intermediate circuit capacitor to the semiconductor components. The intermediate circuit line may extend perpendicular to a direction of flow for the coolant in the heatsink on a side of the semiconductor components facing away from the heatsink.
