As you know, Koenigsegg is one of the very few carmakers who design and develop most of the automotive components in-house, including the engine and its related bits and bobs, and also the transmission—or the lack of it. Now the company has in-house developed a new SiC (silicon carbide) six-phase inverter called ‘David’, which will be used on the upcoming Gemera family hypercar. The Gemera which debuted in March 2020, during the peak of the pandemic, is yet to enter production.
But anyway, David weighs about 15 kg (33 lbs) and has a volume of about 10 liters. A beverage can has been placed next to it for scale. The compact inverter can pump out 1300 ARMS AC at 850-volt (DC) over six phases; in simple terms—up to 750 kW (1,020 metric hp). The Gemera would need two such inverters where up to 12 phases (6 per motor) can pump out 1.5 MW (2,040 metric hp)—claimed to be a new benchmark.
“As the inverter is smaller, lighter and more powerful than what we could find out there, we named it David, like in the story of David and Goliath,” said the boss Christian von Koenigsegg.
Fully sealed housing and quick connectors allow safe connection without opening the casing or using special tooling, says the company. David is also claimed to be optimized for harsh automotive environments and designed to emit low electromagnetic emissions. David runs on proprietary software that is continuously upgraded Over-The-Air.
“I am very excited that our high voltage team can stay ahead of the curve in a very competitive E-mobility landscape in true Koenigsegg fashion. I am also thrilled that we can offer this ground-breaking technology as components to visionary companies and entrepreneurs. Sharing these components enables Koenigsegg to have an impact on CO2 reduction,” added Mr. Koenigsegg.
