Overheating components significantly limit the performance of drivetrains in electric vehicles. Inverters in particular are subject to a high thermal load, which is why they have to be actively cooled. In the Dauerpower project, Fraunhofer IZM is working with project partners from the automotive industry to develop an electric inverter that can work at a lower operating temperature thanks to optimized cooling management, resulting in a lower power loss. In addition to longer full-load utilization, the required semiconductor area can also be reduced as a result, which can further decrease the costs of the electric mobility transition.
