High-voltage SiC devices: Diodes and MOSFETs

Abstract

This paper reviews recent achievements on high-voltage SiC-based devices aimed at Wind Power and Solid-State Transformer applications. SiC diodes with voltage ranges between 1.7kV and 9kV have been designed and fabricated. On the other hand, SiC JFETs and, specially, SiC MOSFETs are also under development, and preliminary prototypes of 3.3 kV SiC MOSFETs are reported.
