Thyristor switch model for power electronic circuit simulation in modified SPICE 2

Modifications to the commercially available SPICE 2 program that allow the accurate simulation of thyristor circuits are discussed. A near-ideal switch model of a thyristor is developed using resistive components, thus eliminating the problems associated with transistor models. The simulator SPICE 2G.6 is modified and a new input format for the thyristor is implemented. Examples of simulations with the new model agree closely with theoretical and experimental investigations.<
