Analysis and sensitivity of periodically switched linear networks

A completely general computer-oriented method for exact frequency-domain analysis of multiphase periodically switched linear networks is presented. Input signals can be either continuous or sample-and-held. The theory is valid even for cases where the network variables are discontinuous during switching. An algorithm to compute sensitivity of the response to element changes is also given. The method unifies analysis of general switched linear networks and ideal switched capacitor networks to a single algorithm. Equation formulation is based on the two-graph modified nodal analysis. The theoretical results presented are compared to previously published results. The theories have been implemented in a computer program. Numerical results of the analysis of three networks are given. They show the usefulness of the program in the analysis and design of switched networks
