Abstract
The physical mechanisms for current saturation and destructive failure of the dual channel emitter switched thyristor (EST) are described. Forward Biased Safe Operating Areas (FBSOAs) at short-circuit state of the 600 V and 2500 V dual channel ESTs are reported. It is demonstrated by numerical simulation that the EST offers a better FBSOA than the IGBT. Experimental measurements are reported that corroborate these calculated results.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
