BERLIN—Inverters are subject to a high thermal load and overheating, which can significantly limit the performance of EV drivetrains. To address the issue, engineers at the Fraunhofer Institute for Reliability and Microintegration (IZM) are developing a device that can work at a lower operating temperature thanks to optimized cooling management, resulting in a lower power loss. They are working with Porsche AG Robert Bosch GmbH on the project.
The compact three-phase drive inverter features a high continuous output of 720 kilowatts or 979 horsepower and a rated current of 900 amperes.
