General Motors and Wolfspeed have announced a strategic supplier agreement to develop and provide silicon carbide power device solutions for GMโs future electric vehicle programs.
Wolfspeedโs silicon carbide devices will enable GM to install more efficient EV propulsion systems that will extend the range of its rapidly expanding EV portfolio.
The silicon carbide will specifically be used in the integrated power electronics contained within GMโs Ultium Drive units in its next-generation EVs.
As a part of the agreement, GM will participate in the Wolfspeed Assurance of Supply Program (WS AoSP), which is intended to secure domestic, sustainable and scalable materials for EV production.
The silicon carbide power device solutions will be produced at Wolfspeedโs 200mm-capable Mohawk Valley Fab in Marcy, New York, which is the worldโs largest silicon carbide fabrication facility. Launching in early 2022, this state-of-the-art facility will expand capacity for the companyโs silicon carbide technologies, which are in increasing demand for EV production and other advanced technology sectors around the world.
The widespread adoption of silicon carbide as an industry standard semiconductor for transportation supports the automotive industryโs rapid transition to clean energy vehicles.
Silicon carbide enables greater system efficiencies that result in longer EV range while lowering weight and conserving space.
Wolfspeedโs technology is fueling electric propulsion systems across the entire voltage spectrum โ from 400V to 800V.
