BorgWarner has solidified its place as a Tier 1 provider whose parts and modules incorporate silicon carbide semiconductor (SiC) know-how due to a half-billion greenback funding in Durham, N.C.’s Wolfspeed, Inc.
Wolfspeed gives silicon carbide semiconductors for energy-efficient merchandise. The corporate’s silicon carbide product households embody power-switching gadgets and RF gadgets focused for varied functions corresponding to electrical autos, quick charging, 5G, renewable power and storage, and aerospace and protection.
EV startup Lucid Motors, a notable proponent of silicon carbide know-how as mentioned on this Design Information article, makes use of Wolfspeed’s XM3 Silicon Carbide energy modules in its flagship Lucid Air luxurious sedan. The XM3 energy modules’ low switching losses, minimal resistance, and excessive energy density contribute to the effectivity and energy density of Lucid’s 163-lb, 670-hp (74kg 500kW) electrical motor.
BorgWarner’s $500 million funding assures entry for the corporate to $650 million price of Wolfspeed’s silicon carbide semiconductors yearly to be used within the parts BorgWarner provides to carmakers. “Silicon carbide-based energy electronics play an more and more vital function for our clients as our electrical car enterprise continues to speed up,” mentioned Frédéric Lissalde, President and CEO of BorgWarner. “We consider this settlement helps be sure that BorgWarner could have a dependable provide of high-quality silicon carbide gadgets, that are vital to the corporate’s inverter progress plans.”
Wolfspeed will assist the rising demand for its merchandise with expanded manufacturing. The corporate is engaged in a multi-year, $6.5 billion capability growth effort which incorporates not solely the set up of extra instruments at Wolfspeed’s 200mm Mohawk Valley, N.Y. fab but in addition the development of a 445-acre silicon carbide supplies facility in North Carolina, which can present a ten-fold growth on the corporate’s present supplies capability. The primary part of development in North Carolina is scheduled for completion by the top of 2024.
Along with provider clients, Wolfspeed can also be promoting on to OEMs, with the October announcement of a take care of Jaguar Land Rover for Wolfspeed SiC semiconductors for use in Jaguar Land Rover energy inverters for future EVs.
BorgWarner has OEM clients eagerly anticipating silicon carbide parts, with manufacturing by a European carmaker on observe for 2023. The inverter BorgWarner will ship options dual-sided cooled energy switches. These promise enhanced driving efficiency and an extended vary for the automotive they are going to be utilized in.

Based on BorgWarner, its new know-how reduces semi-conductor space and SiC materials, providing a lighter and smaller system at a decrease value in comparison with different silicon-based inverters. The corporate states that the inverter has better sturdiness by its wire-bondless energy change design during which the silicon-isolated gate bipolar transistor energy switches have been changed by SiC metal-oxide-semiconductor field-effect transistor energy switches. The result’s a promised 70 p.c discount in switching losses, which lets carmakers enhance efficiency and scale back prices for his or her electrified propulsion programs.
BorgWarner says the corporate is focusing on $4.5 billion of electrical car income for 2025, in comparison with lower than $350 million in 2021.
