The ruggedness of SiCGT (SiC Commutated Gate Turn-off Thyristor) was investigated. The SiCGT was confirmed to operate at over 1200oC, a higher temperature than Si device's destruction temperature. The SiCGT endured a large current of over 2000A (2470A/cm2) per one chip. Positive temperature coefficient resistor behavior could be found during the destruction… CONTINUE READING
