Automatability of consistent switches state search in computer aided analysis of switched RLC networks

In this paper a method for the formulation of switched RLC (SRLC) circuit equations is discussed. The method is aimed at providing a suitable data structure for time-domain simulations, supporting the automatic determination of the topology entered by SRLC nets after forced commutations of any switching device. The data structure consists in a Master-Slave Connection Matrix, defined using the compensation theorem, which permits a straight evaluation of the influence of the forced commutation of any switch upon the currents of all switching devices in the net. Problems connected to the presence of controlled sources are discussed. Some applications to the simulation of power electronic circuits are presented.
