Wolfspeed’s founders were the first to successfully commercialize Silicon Carbide, and for more than 35 years have focused on designing and supplying the industry’s highest-performing Silicon Carbide and GaN-on-Silicon-Carbide materials and devices for high-power applications.

In 2015 Wolfspeed acquired Arkansas Power Electronics International Inc. (APEI), which specialized with approx. 50 employees in wide-bandgap advanced and high-performance power modules for a variety of customers and applications, including the defense, aerospace and automotive markets. Since its foundation in 1997, APEI created more than 100 patents and developed a broad power module portfolio above 10,000V and 1,000A.

The acquisition combined two experts with complementary skills to define the ideal combination of device and packaging technology to set the industry standard for power modules.

Today, Wolfspeed’s Power Module Business Unit with almost 150 people globally is developing and offering Silicon Carbide optimized power modules for mainly I&E, automotive and MV/HV applications.
