In this paper, an improved approach for the modeling of power thyristors is presented. A modified two-transistor configuration based on the Gummel-Poon model is applied. This model takes into account the conductivity modulation and carrier-carrier scattering by using nonlinear current sources. The current gain of the transistor is studied relating it to the injection level in order to provide a more insight of some SPICE parameters. The design parameters of the thyristor are related to circuit parameters using some analytical expressions. Then, the SPICE model parameters are extracted using Silvaco. The simulation results are compared with measurements showing good agreement indicating that the developed model could efficiently describe the performance of the thyristor under various practical operating conditions.

In this work, a new SPICE model is developed for power thyristors, which contains amplifying gate and emitter-shorts. This model is based on the two-dimensional two-transistor circuit model of a thyristor. The authors use Gummel-Poon circuit model that takes into consideration the high injection effects and the conductivity modulation of the low n-doped region. The model parameters are defined and extracted according to a new methodology. The simulation results are compared with experimental measurements. It has been found that the developed model satisfactorily describes the performance of the thyristor under practical operating conditions.
