Abstract
An electric power converter device includes a first power semiconductor module and a frame for a closed cooler. The first power semiconductor module includes a first base plate having a first main side, a second main side opposite the first main side and a lateral side surface extending along a circumferential edge of the first base plate and connecting the first and the second main side. The frame is attached to the second main side of the first base plate. The first base plate has a first step on the second main side along the circumferential edge of the first base plate to form a first recess along the circumferential edge of the first base plate, in which first recess a first portion of the frame is received.
