Abstract
A power electronics arrangement for an externally excited synchronous machine, may include an inverter power module for each phase of the synchronous machine to form an inverter, an exciter power module including an exciter circuit as well as a common heat sink, to which the power modules are secured and thermally coupled for cooling. The heat sink may comprise a cavity including cooling structures for each inverter power module, each cooling structure being situated adjacent to a respective inverter power module. The cavity may receive a flow for active cooling of the power modules of a cooling fluid entering through an inflow opening of the heat sink to an outflow opening of the heat sink. A cooling structure may be associated with the exciter power module, the cooling structure being adjacent to the excited power module in the cavity.
