Koenigsegg said it has developed a six-phase traction inverter using SiC power semiconductors for its upcoming Gemera supercar and named it David.

"Since the inverter is smaller, lighter and more powerful than anything we find there, we named it David, just like the story of David and Goliath," Koenigsegg founder and CEO Christian von Koenigsegg said.

The inverter weighs 15 kg and has a volume of 10 liters. It can provide 1,300 Arms of 850V DC six-phase AC power and support up to 750kW of power. In the dual configuration installed in Gemera (weight 30 kg, volume 20 liters), there are 12 phases (6 phases per motor), and the output power is 1.5 MW.

David uses proprietary Koenigsegg flexible algorithms and software, which may be continuously upgraded wirelessly. It can independently run two motors or one motor up to 750kW. Using a completely sealed shell and quick connector, a safe connection can be achieved without opening the shell or using special tools.

HV Systems project leader Boris Baskevitch commented: "The result of this new integrated high-performance powertrain is top power density, efficiency and system integration-this is Koenigsegg's demonstration of taking performance technology to a new level."

Together with the Koenigsegg electric motors, batteries and controllers that have not yet been made public, the inverter was developed under the ISO 26262 regulatory framework and international high-voltage safety standards. For this reason, it is optimized for the harsh automotive environment and designed for low electromagnetic radiation. The device is also available in a version that directly integrates with Koenigsegg motors through the bus, as an alternative to independent integration through cables. Integrating the motor with the inverter reduces the volume to an impressive 9 liters.

Von Koenigsegg concluded: "I am very pleased that our high-voltage team can maintain a leading position in the highly competitive electric vehicle field with true Koenigsegg fashion. I am also very happy that we can provide this breakthrough technology as a component to visionary Companies and entrepreneurs. Sharing these components allows Koenigsegg to have an impact on CO2 reduction. Please stay tuned for more news in this area!"

With 1.27MW of power and 3,500Nm of torque, Koenigsegg Gemera accelerates from 0-100km/h in 1.9 seconds
