Characterization and comparison of commercially available silicon carbide (SIC) power switches

In this paper the electrical and thermal characteristics of commercially available SiC devices, normally-on and -off JFETs as well as a MOSFET, and of a high-voltage Si- MOSFET are presented. The mentioned characteristics are compared and it is shown which characteristics are the limiting factors when designing power electronics devices based on SiC power switches. (6 pages)
