Abstract

In this work a new SCR model is developed by applying the Gummel-Poon circuit model to the two-transistor configuration. This model naturally takes into consideration the high injection effects. Conductivity modulation is taken into consideration by using nonlinear current sources. The model parameters are defined and extracted according to a new methodology. The simulation results are compared with the measured results. The developed model satisfactorily describes the performance of the thyristor under practical operating conditions.
