Dynamic Processes in Electrical Circuits with Nonlinear Passive Elements

A lot of electrotechnical systems are nonlinear, that is why the study of dynamic processes in nonlinear electrical circuits is very important and advisable. Dynamic analysis is performed in electrical circuits with nonlinear passive elements. Such elements include nonlinear resistors, which are described by the piecewise-linear volt-ampere characteristics, inductances and capacities. The analytic analysis of some nonlinear circuits, as well as the results of their numerical analysis in the MATLAB system are represented. The importance of the numerical analysis study is emphasized, since the complexity of electrotechnical systems makes it difficult to build their analytical models in practice.
