Abstract
A self-commutated power converter of a voltage-impressing converter having n high-power modules is described. These high-power modules are joined phasewise to a phase heat sink, respectively, in a detachable manner, and joined, one over another, to a partition in such a manner that their cooling fins protrude through openings of this partition into a ventilation space and each run horizontally, an air-discharge duct being arranged in the ventilation space, the air-discharge duct being designed in such a manner that the cooling air of the ventilation space flows laterally, in each case on both sides of the phase heat sinks, between the cooling fins into the air-discharge duct. Thus, a self-commutated power converter of a voltage-impressing converter is obtained whose size, weight and cost are considerably reduced compared to a power converter having a conventional design, and whose high-power modules are each fully utilized in terms of capacity.
