Abstract
A power electronics device for controlling an electric machine including a power section arranged within a housing which can be closed via a cover element. The power section has a plurality of capacitors and a plurality of power semiconductors which are connected to a power bus bar. In addition, a control device is provided for controlling the power electronics device. The capacitors, power semiconductors, and control device are cooled via a cooling device which is formed as a profile having an essentially U-shaped cross section. The cooling device has two lateral limbs and a base region through which cooling ducts are arranged. A suitable cooling medium flows through the cooling ducts and the ends of the cooling ducts opposite the housing cover are closed by a covering element. The capacitors, the power semiconductors and the control device are connected to the cooling device such that thermal exchange occurs between these components and the cooling device.
