Automotive supplier Vitesco Technologies has signed a second cooperation agreement with Infineon Technologies for silicon carbide (SiC) power devices.
Silicon carbide plays a key role in increasing the efficiency of high-voltage power electronics in the drive systems of electrified vehicles and Vitesco uses SiC components in its compact high-voltage inverters that control electric drive motors.
“Partnering-up with leading semiconductor manufacturers is important for us to master dynamic growth. We have been collaborating with Infineon on silicon for a long time. We are now expanding this with SiC power semiconductors. Jointly refining chips specifically for our applications, in the area of electromobility, will lead to highly attractive solutions. This is another important step forward into the future of electrification,” said Andreas Wolf, CEO of Vitesco Technologies, based in Germany.

“In silicon carbide, Infineon is a technological and quality leader,” said Dr. Stephan Zizala, head of the Automotive High Power business unit at Infineon Technologies. “Our second silicon carbide generation enables us to develop even more compact and efficient systems. With our decades of experience and continuous expansion of manufacturing capacities, we are well positioned for the accelerated growth of the SiC market.”
Compared to silicon IGBTs, SiC offers an efficiency advantage, especially at a battery voltage of 800V which subsequently then affects the range of an electric vehicle. “Range is a key performance characteristic in battery electric driving, higher efficiency power semiconductors such as SiC will therefore be increasingly used in the future,” said Thomas Stierle, member of the executive board and head of the Electrification Technology business unit at Vitesco Technologies.
For Vitesco Technologies, this is the second partnership in SiC devices. “We have had excellent experience with the partnership already underway and have industrialized initial applications,” said Stierle. In view of the strong order intake for electric drives, for example for very compact axle drives, the broad supply base is a strategically important course setting and ensures long-term success.”
