GaN chip technology for high-voltage automotive applications

Working in cooperation with a global leader in gallium nitride (GaN) solutions, we present technologies representing the next step for the electrical drivelines of the industry, which show performance comparable to SiC at reduced costs up to factor 2.

Form-litz-wiring technology to meet the growing demand for power density

It achieves slot copper fill factors of up to 65% despite the thin individual wires, which results in high continuous power at maximum speed and high motor efficiency. It guarantees an extended motor life even during the fast inverter switching processes. 

3-Level Inverter and HV booster technologies for high efficiency, noise optimization, drastically minimized losses and compatibility of 800V powertrains with currently available 400V charging infrastructures.

E-Torque Vectoring reaches outstanding safety and stability levels, increased traction and cornering dynamics. This solution allows customization of driving characteristics and expandable functionality through our modular software, ensuring that next-gen solutions are ready to hit the road in no time.

Discover our groundbreaking ultra-fast charging storage solutions, such as our BlueFire Battery Technology. Find out what our engineers have achieved since we presented it to the world at the Battery Show in 2021. Find out how this ultra-fast charging solution can bring maximum efficiency to the race tracks and into high-performance vehicles of the extra class. 

ONEBox Electric Drive Unit

Our highly versatile Electric Drive Unit for a wide range of applications in a compact design is going into the next development phase, aiming at 800V applications. This solution is highly cost-efficient and customizable, allowing the installation of e-motors of different power levels.
