Viper - 800 Volt Silicon Carbide Inverter

Our CLEPA Innovation Award winning 800-Volt Silicon Carbide Inverter unleashes electric propulsion system power and performance to advance Electrified Vehicles.

Studies show the major factors holding consumers back from purchasing a plug-in hybrid (PHEV) or battery electric vehicle (BEV) are battery range, charging convenience and costs. Our solution for this challenge? The 800-Volt Silicon Carbide Inverter for Electrified Vehicles.

Viper is the first 800-Volt inverter to use an innovative, double-side cooled silicon carbide (SiC)-based power switch that delivers the higher power densities and efficiencies needed to extend battery range and performance, and reduce costs.

Its patented capabilities give manufacturers the propulsion system design flexibility and performance they need to drive consumer demand - and the vehicle mix and volumes required to meet increasing emissions regulations.


Small switch, packs a big punch

Inverter comparison

The inverter’s specific features include extending PHEV and BEV range by approximately 5% and enabling faster charging times at 800 volts when compared to today’s 400-volt systems. Its patented, dual-sided cooling allows for significantly smaller and lighter designs - while reducing the amount of Silicon Carbide needed for each switch, thereby cutting costs.

Viper is engineered to deliver up to a 70% reduction in power losses, along with greater power density, depending upon the drive cycle. Manufacturers can leverage these improved efficiencies when designing their propulsion systems to either boost vehicle range, improve overall performance or reduce sticker shock through less costly batteries.

This flexibility allows manufacturers the means to present consumers with a range of performance options - including the ability to trade-off battery size, cost and vehicle range - available at multiple price points, which is similar to the way powertrains are marketed today.

Lastly, the 800-Volt Silicon Carbide Inverter for Electrified Vehicles can be scaled and adapted to lower and higher voltage systems, giving manufacturers much-needed economies of scale managing the multiple voltages and current levels required by PHEVs and BEVs.

The 800-Volt Silicon Carbide Inverter for Electrified Vehicles, with its breakthrough features, is a game-changer for the industry that manufacturers can use to create the compelling buying propositions that lead to greater acceptance and therefore sales for these new means of mobility.
