Abstract: Arrangement for a power electronics unit in a hybrid vehicle power train, where all attachment points have a total thermal conductivity corresponding to less than 10 degrees temperature difference on a Kelvin-scale between electronics of said power electronics unit and the outside of said first transmission side for 5 kW of heat originating from one side of said attachment point. Arrangements including sound damping capabilities are disclosed. The arrangement can provide fewer parts and increased functionality of the power electronics unit.

Abstract: In an arrangement for a power electronics unit in a HEV, the HEV including a combustion engine, an electric motor/generator, a transmission, the power electronics unit is shaped as a plate. The plate is extended along a transmission side, the power electronics unit is fixed to the power train with a first attachment point. All attachment points have a total thermal conductivity corresponding to more than 10 degrees temperature difference on a Kelvin-scale between the power electronics unit and outside surface of said first transmission side and/or outside surface of the motor/generator for 5 kW of heat originating from one side of said attachment point. Embodiments also including sound damping capabilities are disclosed. The arrangement facilitates use of fewer parts and increased functionality.
