Power electronic arrangement for an electric machine and motor vehicle

A motor vehicle, comprising:

• an electric machine that operates as a traction machine;
• and
• a power electronic arrangement associated with the electric machine,
• wherein the power electronic arrangement includes:
• an inverter;
• a plurality of power electronic components accommodated in at least one power module;
• an intermediate circuit connected to the inverter across connection contacts of the at least one power module and having at least one intermediate circuit energy accumulator, and a heat sink to which the at least one power module is thermally connected for cooling,
• wherein the connection contacts are arranged at a margin and flat against a substrate carrying one or more power semiconductors, and are thermally coupled to the heat sink via the substrate, and
• wherein the at least one intermediate circuit energy accumulator is connected electrically and thermally to the connection contacts to cool the at least one intermediate circuit energy accumulator.
