A new computer-oriented method for an efficient and accurate large-signal time-domain analysis of switched networks is presented. Switched networks consisting of strictly linear elements and of a wide class of switches can be investigated.

When network topology changes, the equations are derived systematically by means of a generalized formulation of the p-port constraint 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.

Abstract
A new computer-oriented method for an efficient and accurate large-signal time-domain analysis of switched networks is presented. 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 network topology changes, the equations are derived systematically by means of a generalized formulation of the p-port constraint 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.
