An electric train crosses through the woods representing how Wolfspeed’s Silicon Carbide solutions run more efficiently and reliably than silicon products.
Industrial

Trains & Traction

The higher operational speeds of Wolfspeed SiC components give designers the tools to create railcar power systems which are up to 50% smaller and 30% lighter than existing systems.

Wolfspeed SiC Solutions for Trains and Traction

A locomotive can pull a mile of train cars thanks to the high-torque electric traction motor. Electric vehicles, roller coasters, and a vast assortment of transportation categories the world over also use this technology, which is controlled by switching electrical current frequency and voltage and through manipulation of magnetic fields. But did you know that all of it runs more efficiently and more reliably because of Wolfspeed Silicon Carbide (SiC) solutions?

Trains and traction, powered by Wolfspeed Silicon Carbide

When railcar power system engineers design with Wolfspeed Silicon Carbide, they are able to deliver solutions that are smaller and lighter than systems built on traditional silicon. With Wolfspeed Silicon Carbide, engineers can use fewer components to perform the same jobs at higher levels of performance due to the unique power characteristics of wide-bandgap silicon carbide.

Wolfspeed — minimize size without sacrificing performance

Wolfspeed Silicon Carbide is built for the future of train and traction power system design. Wolfspeed Silicon Carbide offers unparalleled performance, with lower thermal losses and increased reliability. For railcar systems in which failure can mean supply chain disruption (or worse), turn to Wolfspeed SiC.
