Abstract:
A self-commutated power converter of a voltage-impressing converter, comprising:phase heat sinks having cooling fins;high-power modules detachably joined phase-wise to the phase heat sinks;a partition, the phase heat sinks being joined, one over another, to the partition so that the cooling fins of the phase heat sinks protrude through openings of the partition into a ventilation space, each of the phase heat sinks extending in a horizontal direction; andan air discharge duct configured so that cooling air of the ventilation space flows laterally, on both sides of each of the phase heat sinks, between the cooling fins of each of the phase heat sinks into that air-discharge duct, the cooling air being sucked out of the air discharge duct by a fan.
