800-Volt Silicon Carbide Inverter
Our 800-Volt Silicon Carbide Inverter for Electrified Vehicles uses 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.
The inverter’s SiC technology can help extend electric vehicle range by c.5% and enables faster charging times at 800-volts when compared to today’s 400-volt systems.

Features / Benefits
- Viper power module includes dual-sided cooling for enhanced thermal management
- SiC helps extend PHEV and BEV range by approximately 5% and enables faster charging times - delivering a better solution with more power, in a smaller package and for less cost.
- Award winning, patented technology eliminates the need for wired bonds or connections that can be the cause of quality and reliability issues.
- Optimizes switching and conduction to deliver up to 70% reduction in power loss
