Power converter e.g. multi polarity inverters, has second circuit carrier arranged in which logic portion is implemented and encapsulated power module, which is provided with electronic circuit portions

摘要

The converter has a first circuit carrier in which a high current region is implemented. A second circuit carrier is arranged in which a logic portion is implemented. An encapsulated power module (26) is provided with electronic circuit portions (50, 52). An interface module is assigned to the first circuitry carrier. Coupling modules are formed as ferrite cores. A coupling device is encapsulated in a housing of a spacer transducer. A cooling module is arranged in the housing.
