General Motors and Wolfspeed (formerly Cree) have entered an agreement to develop and provide silicon carbide power devices for GM’s electric vehicle programs. The silicon carbide will be used in the integrated power electronics contained within GM’s Ultium Drive units.
The silicon carbide power devices will be produced at Wolfspeed’s 200 mm-capable Mohawk Valley Fab in Marcy, New York. Wolfspeed’s technology is fueling electric propulsion systems across the voltage spectrum, from 400 V to 800 V.
“Our agreement with Wolfspeed represents another step forward in our transition to an all-electric future,” said GM VP Shilpan Amin. “We see silicon carbide as an essential material in the design of our power electronics to meet customer demand.”
“Our agreement with GM further demonstrates the automotive industry’s commitment to delivering EV solutions to the market and using the latest advances in power management to improve overall vehicle performance,” said Gregg Lowe, CEO of Wolfspeed. “This agreement ensures long-term supply of silicon carbide to GM.”
