Abstract
A converter arrangement includes a housing having a first cooling air channel, at least one capacitor disposed in the housing, a fan for generating a cooling air flow, and a first power electronics module disposed in the housing between the at least one capacitor and the fan, as viewed in a direction of the cooling air flow. The first power electronics module is positioned in relation to the fan so as to only be cooled by a first partial air flow. A second partial air flow provided for cooling the at least one capacitor is routed via the first cooling air channel past the first power electronics module such that the second partial air flow is thermally separated from the first power electronics module.
