SiC – A Yin and Yang Perspective

Worldwide ramp-up of electromobility is resulting in a huge demand of wide bandgap semiconductor materials like silicon carbide. The hype for SiC is ongoing, the material allows higher efficiency in power conversion, but is currently at higher cost than conventional silicon-based technology. This presentation will focus on latest SiC innovations in material development, device structures and drivetrain concepts, and shows how, all put together, enables not only efficient, but most importantly affordable electrification. Efficient and affordable aspects need to get in balance like in Yin and Yang philosophy.
