Abstract

This contribution presents a new method for time-domain analysis of linear and nonlinear circuits with ideal switches controlled by internal circuit variables. At switching instants due to instantaneous changes of circuit topology instantaneous jumps of charge and flux occur if initial conditions before and after the switching instant are inconsistent. We propose a method for calculation of these jumps and of the initial conditions from dedicated charge and flux substitute networks based on charge and flux conservation laws
