Silicon carbide-based power modules for increasing the efficiency and range of electric vehicles


Innovations in electronics will further increase the efficiency of the drive system of electric vehicles and thus their range. Silicon carbide (SiC) semiconductors will play a special role in this context, enabling power electronics that control energy flows in vehicles to become more compact and efficient. Intelligent electronics for control and monitoring will also ensure the reliability of future drives, even in the event of a failure.




With the help of modular SiC-based power electronics, this project aims to achieve a highly energy-efficient and demand-oriented control of the drive of electric vehicles, thus increasing the range. To this end, novel assembly and connection technologies such as embedding technology, innovative circuit topologies and solutions for improved heat dissipation for SiC power modules are being researched. The project focuses on the research of power module structures which make use of the full potential of the SiC semiconductors by improving the thermal and electromagnetic properties as well as the control and at the same time minimize the required semiconductor area. The goal of the subproject of the University of Stuttgart is the conception, design, application and analysis of active load cycling tests under consideration of the specifics of SiC power semiconductors and general conditions resulting from the high degree of integration, 3D integration and PCB embedding. For this purpose, novel control methods and topologies for active power cycling tests are being researched.
