Delphi Technologies to Partner with Cree for Automotive Silicon Carbide Devices
Innovative MOSFETS are expected to increase driving distances, shorten charging times, and deliver overall improved efficiency for next generation electric vehicles
DURHAM, N.C.–Delphi Technologies PLC, and Cree, Inc., will partner to use silicon carbide semiconductor device technology to enable faster, smaller, lighter, and more powerful electronic systems for future electric vehicles (EVs), the companies said in a press release. Delphi Technologies is a global provider of automotive propulsion technologies; Cree is a provider of silicon carbide semiconductors.
The companies anticipate that 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 Technologies is committed to providing pioneering solutions to vehicle manufacturers,” said Richard F. (Rick) Dauch, CEO of Delphi Technologies, in the release. “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. IHS estimates that, by 2030, 30 million high voltage electrified light vehicles will be sold, representing 27 percent of all vehicles sold annually. Inverters are one of the highest-value electrification components, and their efficiency has an industry-changing impact on many aspects of vehicle performance, according to the companies.
“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, in a statement. “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.”
Cree (www.cree.com) said in the release that it is committed to leading the global transition from silicon to silicon carbide. The company recently announced an expansion that it said would generate up to a 30-fold increase in silicon carbide capacity. Cree offers a comprehensive set of silicon carbide and GaN (Gallium nitride) power and RF (radio frequency) components through its Wolfspeed® business unit.
Delphi Technologies’ (www.delphi.com) new silicon carbide inverter, operating at 800 volts, will provide vehicle engineers with additional flexibility to optimize other powertrain systems, the company reported. 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.
