Efficient powertrains for electric vehicles are crucial for reducing fossil fuel reliance, with the inverter playing a key role in converting battery power into energy for electric motors. Fraunhofer IZM, in collaboration with Porsche and Bosch, is developing a high-output three-phase drive inverter with impressive performance gains compared to traditional silicon-based inverters. By using innovative silicon carbide transistors and advanced cooling elements, the new system achieves a 20%-30% increase in power density. The use of 3D-printed copper cooling elements and enhanced modularity in the prototype promise a resource-efficient solution for electric vehicle production. The project received EUR 1.2 million in funding for further development and testing before potential series production.
