State-of-the-art SIC six-phase inverter
Fully developed in-house for the upcoming Gemera and other future needs, Koenigsegg's new inverter David weighs only 15 kg with a volume of 10 liters. The ultra-compact inverter kicks out 1300 ARMS AC at 850 V (DC) over 6 phases, with up to 750 kW of power. In double configuration (30 kg of weight with a volume of 20 liters) as mounted in the Gemera, there are 12 phases (6 per motor) with an output of 1.5 MW, which is truly a new benchmark.
As the inverter is smaller, lighter and more powerful than what we could find out there, it has been named David, like in the story of David and Goliath.
David runs on proprietary Koenigsegg flexible algorithms and software that is continuously upgraded over the Koenigsegg cloud via OTA. It is capable of either running two motors independently or one motor up to 750 kW. Fully sealed housing and quick connectors allow safe connection without opening the casing or using special tooling. David also comes in versions directly busbar integrated with Koenigsegg E-motors, as an alternative to stand-alone integration via cable (doing so shrinks the inverter down to around 9 liters in volume).
David is optimized for harsh automotive environments, designed to emit low electromagnetic emissions and developed under the ISO 26262 regulatory framework and international high voltage safety standards. The inclusion of David as part of Koenigsegg's new integrated high-performance powertrains will result in top-rated power density, efficiency and system integration.
A part of Koenigsegg’s total in-house HV architecture
David is a part of Koenigsegg’s ground-up, in-house developed complete HV architecture which includes, but is not limited to, E-motors, batteries and controllers. As David and the other newly developed Koenigsegg HV components are aerospace-grade, there is also the possibility to apply them for VTOL or other similar needs with further certifications.
