Dependences of on-state propagation velocity on thyristor geometric parameters

The article considers the study results of on-state linear propagation velocity dependences on current density in open thyristors by varying the values of their geometric parameters. The study was carried out on the basis of modelling of thyristor turn-on in Synopsys TCAD software environment. The approximation dependences of on-state propagation velocity on thyristor geometric parameters are presented.
