Delphi Technologies has entered into a partnership with Cree, a silicon carbide semiconductors company. The companies aim to utilize silicon carbide semiconductor device technology to enable faster, smaller, lighter and more powerful electronic systems for future electric vehicles (EV).
According to companies, Cree’s silicon carbide-based MOSFET (metal–oxide–semiconductor field-effect transistor) technology coupled with Delphi Technologies’ traction drive inverters, DC/DC converters and chargers will extend driving range and deliver faster charging times of EVs, while also lowering weight, conserving space and reducing cost.
Cree is aims to lead the global transition from silicon to silicon carbide and recently announced silicon carbide capacity expansion to generate up to a 30-fold increase in capacity. The company offers a comprehensive set of silicon carbide and GaN (Gallium nitride) power and RF (radio frequency) solutions through its Wolfspeed® business unit.
Delphi Technologies’ new silicon carbide inverter operating at 800 Volts will provide vehicle engineers with additional flexibility to optimize other powertrain systems. Options include more range or a smaller battery; ultra-fast charging or smaller, lighter, cheaper cables; and greater harvesting of vehicle kinetic energy when braking, further extending vehicle range.
The adoption of silicon carbide-based power solutions is rapidly growing across the automotive market as the industry seeks to accelerate its move from internal combustion engines to EVs. Inverters are one of the highest-value electrification components and their efficiency has an industry-changing impact on many aspects of vehicle performance.
