Vitesco does deal with Infineon for silicon carbide power semiconductors

Vitesco Technologies has signed a collaboration agreement with Infineon Technologies AG. Infineon is a leading manufacturer of automotive electronics semiconductors and a leading global supplier of power semiconductors made from the innovative material silicon carbide (SiC).

Silicon carbide plays a key role in increasing the efficiency of high voltage power electronics in electric vehicle propulsion systems. Vitesco Technologies uses SiC components in very compact high voltage converters that control electric drive motors.

As one of the pioneers in electromobility, Vitesco Technologies is already using SiC components in today’s generation of electronics, where they enable small dimensions with high efficiency.

“Partnering with leading semiconductor manufacturers is important for us to master dynamic growth,” said Andreas Wolf, CEO of Vitesco Technologies. “We have been working with Infineon on silicon for a long time. We are now expanding this with SiC power semiconductors. The joint refining of chips specifically for our applications, in the field of electromobility, leads to very attractive solutions. This is another important step forward in the future of electrification.”

“In silicon carbide, Infineon is a technology and quality leader,” said Dr. Stephan Zizala, head of the Automotive High Power business unit at Infineon Technologies. “Our second-generation silicon carbide enables us to develop even more compact and efficient systems. With our decades of experience and continuous expansion of production capabilities, we are well positioned for the accelerated growth of the SiC market.”


SiC power semiconductors are a new trend in voltage layer electronics for electrified drives up to 800 volts system voltage. Compared to conventional silicon semiconductors, SiC offers an efficiency advantage, especially at a battery voltage of 800 volts, which in turn influences the range of an electric vehicle. “Range is an important performance characteristic in battery-powered electric vehicles, which is why more and more higher-efficiency power semiconductors such as SiC will be used in the future,” emphasizes Thomas Stierle, member of the board of directors and head of the business unit Electrification Technology at Vitesco technologies.

For Vitesco Technologies, this is the second collaboration in SiC devices. “We have excellent experience with the partnership already underway and have industrialized the first applications,” said Stierle. Given the strong order intake for electric drives, for example for very compact shaft drives, the wide range is a strategically important course and ensures long-term success.
