A practical SCR model for computer aided analysis of AC resonant charging circuits
Abstract
A method for determining parameters for a two-transistor SCR model from SCR specification sheet data developed by Hu and Ki (1979) for use with the CAD program SPICE2 was examined. The model was found to need improvement in order to simulate the SCR turn-off transient in an inductive circuit. An improved model was then developed for SPICE2 which was demonstrated to perform satisfactorily through simulation of AC resonant charging circuits having one or two SCR's. The original and the modified Hu-Ki models are presented together with the simulation results.
