Abstract: An exemplary power electronics module includes a first power electronics element that generates a first heat flow during operation of the power electronics module, a second power electronics element that generates a second heat flow during operation of the power electronics module. The first cooler is in thermal contact with the first power electronics element to receive at least part of the first heat flow. The second cooler is in thermal contact with the second power electronics element to receive at least part of the second heat flow. A heat exchanger is configured to transmit at least part of the first heat flow and the second heat flow to a primary cooling flow and transfer heat flow in a thermally efficient manner. A magnitude of the heat flow is less than a total magnitude that is formed from a maximum first heat flow and a maximum second heat flow.

Abstract: Exemplary embodiments are directed to a converter system having a phase voltage source, n partial converter systems, wherein n≧1 and, when n=1, the partial converter system is connected to the phase voltage source at a connection point and, when n>1, the partial converter systems are connected to the phase voltage source at the connection point. Furthermore, a power switch is connected in series between the phase voltage source and the connection point. An interruption element is connected in series between the phase voltage source, the power switch, and the connection point to rapidly switch off a fault current via a partial converter system. Furthermore, a power electronic system including m converter systems is specified, wherein m>1.
