A computer-oriented method for a large-signal time-domain analysis of switched networks is presented. The method is based on a state variable approach which exploits an efficient algorithm developed for the systematic formulation of state equations and output equations for linear active networks. Switched networks consisting of linear elements and both externally and internally controlled switches can be investigated. Every switching element is modeled as an ideal switch and the evolution of the network is represented by a sequence of linear circuit topologies. State equations for each topology are systematically obtained through a simple interchange of columns of a reduced tableau matrix. The elements of this matrix are calculated only once at the initial stage of the procedure. Dirac impulses are permitted in the analysis in order to find the correct topology after switching.
