Development of medium voltage SiC power technology for next generation power electronics

Recent developments in 3.3 kV to 15 kV 4H-SiC MOSFETs are discussed, and device merits are compared to traditional Silicon IGBT technology, as well as 15 kV SiC n-IGBTs. Performance near theoretical limits was achieved for the 4H-SiC MOSFETs; bipolar 4H-SiC devices were analyzed and were found to handle higher currents at low frequencies.
