Delphi partners with Cree for automotive silicon carbide devices


Delphi Technologies has partnered with US based Cree to utilise silicon carbide semiconductor device technology to enable faster, smaller, lighter and more powerful electronic systems for future electric vehicles.

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. The Cree silicon carbide MOSFETs will initially be used in Delphi Technologies’ 800 Volt inverters for a premium global automaker. Production will ramp in 2022.

Delphi CEO Rick Dauch said: “Our collaboration with Cree will create a significant benefit to automakers as they work to balance meeting stricter global emissions regulations with consumer appetite for electric vehicles. Overcoming driver anxiety related to electric vehicle range, charging times and cost will be a boon for the industry.”

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.

“Cree’s technology is at the heart of the dramatic change underway in EVs, and we are committed to supporting the automotive industry as it transitions from silicon-based designs to more efficient, higher performing silicon carbide solutions,” said Gregg Lowe, CEO of Cree. “This partnership with Delphi Technologies will help drive the adoption of silicon carbide in the automotive sector. As the world leader in silicon carbide, Cree is continuing to expand capacity to meet market demands with our industry-leading power MOSFETs to help achieve a new, more efficient future.”
