Computer-aided time-domain analysis of switched networks

A new computer-oriented method for an efficient and accurate large-signal time-domain analysis of switched networks consisting of strictly linear elements and of a wide class of switches can be investigated. The switching elements are assumed ideal and the state equation method is adopted for the network description. When a network topology changes, state equations are derived systematically by means of a generalized formulation of the p-port contraint matrices. Each set of equations holds from a switching instant to the next one which is calculated through a Newton-type algorithm. Numerical results are compared with experimental data and SPICE simulations.
