Abstract
The Forward Biased Safe Operating Area (FBSOA) and the Reverse Biased Safe Operating Area (RBSOA) of the new Emitter-Controlled thyristor (ECT) are studied. The high-voltage current saturation mechanism and the turn-off failure mechanism of the ECT are analyzed. It is demonstrated that the ECT has superior FBSOA and RBSOA compared with the IGBT and other known MOS gated thyristors.
