Abstract:
1. A power semiconductor module having a thermally conductive base plate on which at least four substrates are arranged, each substrate having at least one power semiconductor device which dissipates operating heat, the substrates being arranged on the base plate in exactly one single row, and two sets of pressure-exerting apparatuses which can be used to press the base plate onto a cooling area being provided on both longitudinal sides of the base plate parallel to the exactly one single row, wherein the pressure-exerting apparatuses of each of the sets are arranged along one of the longitudinal sides of the base plate and in a row parallel to the at least one single row, wherein at least three of the pressure-exerting apparatuses are disposed along one of the longitudinal sides of the base plate, and wherein at least one of the pressure-exerting apparatuses of the respective set is arranged outside corner regions of the base plate.
