Koenigsegg has unveiled the inverter that it uses in the Gemera. The Swedish company called its inverter David and claims it is a class-leading unit. The Koenigsegg David is designed in-house, and it is a six-phase inverter.
As Koenigsegg explained, the fully developed in-house unit is not meant just for the Gemera, but also for all future needs. That is a sign of things to come, if you ask us. But let us get back to the all-new inverter.
The unit weighs just 15 kilograms (ca. 33 lbs.), and it has an effective volume of just 10 liters (ca. 2.64 gal). The Swedes placed it next to a 330-ml can (ca. 11 oz) for scale. To the Internet's dismay, they did not use a banana to help everyone grasp the size of their six-phase inverter.
David, the inverter from Koenigsegg, can pump out 1300 ARMS AC at 850 V (DC) over six phases, which means up to 750 kW (1,005 horsepower) of power. For good measure, the Koenigsegg Gemera comes with two of these units, which means that it has 12 phases (six per motor), along with a total output of 1.5 MW (ca. 2,011 horsepower).
The unit has a sealed housing and can be connected to the devices it supplies with quick connectors that do not require any special tooling to safely use. It is also worth noting that the unit is developed under the ISO 26262 regulatory framework, which makes it compliant with international high-voltage standards.
Moreover, the Swedish company has also developed a version of its inverter that is directly integrated (through the bus bar) with Koenigsegg e-motors, batteries, and controllers, which allows shrinking the unit to around 9 liters (ca. 2.37 gal) in volume but ditches the stand-along integration with cables.
According to Koenigsegg, David is capable of driving two three-phase motors independently and with torque vectoring. That means that the company can employ it for a lighter and more compact installation of a configuration that has 2x350 kW. That would mean two engines that would each deliver up to 469 horsepower.
The Koenigsegg Gemera has a hybrid system that involves four motors in total, one of which is an internal combustion engine. The other three are electric motors, and the setup provides a maximum of 1,700 PS (1,250 kW or 1,677 horsepower). Peak torque sits at an impressive 3,500 Nm (2,582 lb.-ft.).
