Koenigsegg created David for the superhybrid Gemera

FineAuto

The Swedish company Koenigsegg presented its new development – a six-phase silicon carbide (SiC) inverter, nicknamed David for its small size and high power. In a twin configuration, the converters have a combined peak power of 1.5 megawatts – they will be installed on the Gemera four-engine superhybrid and other Koenigsegg models, but they can also be equipped with vertical take-off and landing (VTOL) aircraft.

The six-phase SiC inverter is entirely developed in-house by Koenigsegg. It weighs 15 kilograms and has a volume of ten liters. The current strength reaches 1300 amperes at 850 volts, the peak power is 750 kilowatts. The converter can be used to power one or two electric motors, and in a paired configuration (16 phases, power 1.5 megawatts), two such devices will be installed on a Gemera superhybrid equipped with three electric motors with a combined output of 800 kilowatts.

David (in honor of the biblical David, who defeated the giant Goliath) works on patented flexible algorithms and Koenigsegg software, which are constantly updated “over the air”. The fully sealed inverter housing is equipped with quick disconnect connectors for safe connection without the use of special tools. As an alternative to traditional cabling, there are inverter versions combined with Koenigsegg motors via a busbar.

And although David was created specifically for Gemera, he will also find application in future products. And since the inverter meets aerospace standards, it can even be installed on VTOL. The advantages of SiC over conventional silicon circuits are obvious: greater stability under sudden temperature fluctuations, high thermal conductivity, low resistance, resistance to radiation and the ability to operate even at temperatures of 600 degrees Celsius.
