Silicon-carbide (SiC) power FETs are finding increased application in the bridge inverters of modern electric vehicles (EVs) as automakers struggle to satisfy the growing demand for products that offer range, performance, and a sticker price equivalent to their fossil-fueled counterparts. But, along with their high efficiency and excellent performance, SiC FETs bring new requirements and design challenges.
This article provides an overview of the role that SiC devices are playing in the next generation of traction inverters, and what it takes to accommodate their unique characteristics.
