The world's best inverter has just been revealed.
Koenigsegg is a marvelous company. Whatever it does, the automaker always sweats the small stuff, and thousands of hours are spent refining and perfecting the smallest details. The Swedish firm has been blowing minds with its astonishingly complex Jesko twins, both of which boast the fastest revving production engine on the planet. With innovations like a 'rocket' catalytic converter, dihedral synchro-helix doors, and Triplex suspension, Koenigsegg should be running out of ideas by now.
But then Koenigsegg revolutionized transmissions with Direct Drive Transmission and later the Light Speed transmission. Okay, so the engineers in Sweden aren't out of inspiration yet, but is their excellence limited to the internal combustion engine? No. Meet David, Koenigsegg's innovative inverter that outperforms everything else on the market.
As usual with Koenigsegg, high expectations for what an inverter should be capable of were not met by what was already on the market. Not a problem - the brand will happily overengineer a solution that fits its needs. This has happened many times in the past and now it has resulted in a "class-leading" SiC six-phase inverter that can produce 1,300 Arms AC at 850 volts (DC) with up to 750 kilowatts of power. It weighs just 15 kilograms (33 pounds) and has a volume of 10 liters (0.35 cubic feet). If you double up (as in the Koenigsegg Gemera), there are 12 phases with an output of 1.5 MW, "which is truly a new benchmark."
Oh, and if you're wondering why it's called David, company founder Christian von Koenigsegg provides a typically fun answer: "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." Cool.
David is both powerful and smart. It runs on proprietary flexible algorithms and software that is continuously upgraded over the Koenigsegg cloud through over-the-air updates and can run either two motors independently or one motor at up to 750 kW. It promises safe connections, outstanding efficiency, and low electromagnetic emissions. Interestingly, David can shrink even further to 9 liters if it is "directly busbar integrated with Koenigsegg E-motors," which are yet to be revealed along with battery and controller solutions. As an aerospace-grade component, it's even suitable for VTOL applications.
Understandably, the boss is proud: "I am thrilled that we can offer this groundbreaking technology as components to visionary companies and entrepreneurs. Sharing these components enables Koenigsegg to have an impact on CO2 reduction. Stay tuned for more news in this area!"
Only Koenigsegg could make an EV technology sound exciting, and we can't wait to see what's next.
