How can 600 kW of continuous power be achieved in electric vehicles without exceeding thermal limits? Dominik Seidenstücker, research associate and expert in power electronics at Fraunhofer IZM, explores this question in an exclusive video tour with the RealIZM blog team.

With the shared »DauerPower« project providing a vivid example, he shows how high-performance inverters are developed and tested for electric vehicles — and what role innovative cooling concepts and materials play in this process.

Technology meets practice: The »DauerPower« project

Working with Bosch and Porsche AG, Fraunhofer IZM has developed a compact cooling system and highly integrated power modules in the joint »DauerPower« project. These components work reliably even under extreme conditions and enable maximum performance with minimal thermal stress.

Thanks to a special process for embedding the semiconductor modules in printed circuit boards, the researchers succeeded in significantly improving system efficiency through lower module inductance. Silicon carbide semiconductors ensure stable temperatures while minimizing switching and conduction losses. In addition, a 3D-printed copper cooler contributes to an efficiency of 98.7 percent.

Joint project: »DauerPower« – SiC inverter electronics for maximum continuous power in the EV powertrain

Funding body: Federal Ministry for Economic Affairs and Climate Protection (BMWK)

Funding code: 19I21023C

Duration: 6/2021 – 12/2024

Project partners: Robert Bosch GmbH and Porsche AG

Data sheet: Drive converter with 600 kW continuous power

Dominik Seidenstücker

Dominik Seidenstücker completed his master's degree in mechatronics at the Beuth University of Applied Sciences Berlin, graduating with a Master of Engineering in December 2020. While still a student, he gained practical experience at IAV GmbH in Berlin, where he spent two years in development and application roles. This period shaped his strong interest in innovative vehicle technology and laid the foundation for his current career.

In 2021, he joined the »Power Electronics« department of Fraunhofer IZM as a research assistant where he works on developing highly integrated inverters and on-board chargers for automotive applications. His responsibilities include project management in its full range - from project management, conceptual development, and design to coordinating production processes and commissioning and optimizing systems. One particular focus of his is the integration of modern semiconductor technologies and transformers into printed circuit board technologies as a way to create compact and efficient solutions.
