Circuit analysis strategy and algorithm based on the diakoptic segregation procedure

摘要

The proposed analysis strategy is based on the “segregation procedure”, meaning the separation between the circuit linear part and the nonlinear one. All types of nonlinearities are accepted, excepting hysteresis phenomena. We accept the general case when the mutual inductors are distributed into different subcircuits. The diakoptic way is assumed for splitting the given circuit into subcircuits, the state variables approach to build the symbolic circuit equations for each subcircuit and the waveform relaxation method for finding the solution. Compared with common approaches of state equations, the main advantage of this procedure is related to the numerical computation quality, thanks especially to the lower order of the equation systems in the mathematical model.
