Abstract :
A rigorous two-dimensional physical model of the GTO thyristor is presented. The model includes the fully coupled effects of self heating of the device during the turn-off phase of operation. The effects of spatially dependent minority carrier lifetime, Auger recombination and carrier-carrier scattering are included in the model. The simulation can be carried out within a realistic external circuit environment
