Abstract

The paper utilises the network topology in the analysis of a thyristor circuit – an oscillating chopper. The graph of the chopper was developed following which the complete incidence matrix was formed. The signal flow graph was also developed, which was reduced directly by the application of Mason's Rule, this being the basis for the formulation of the state equations. For analytical reasons, the diodes and thyristors were classified along with the resistance branches because of their switching properties. The analysis concludes that the problem of varying time constants in the solution of state equations in the thyristor circuits is eliminated by opening the open circuit branches
