Dynamic Characterization of Typical Electrical Circuits via Structural Properties

Abstract EN

The characterization of a class of electrical circuits is carried out in terms of both stability properties and steady-state behavior.

The main contribution is the interpretation of the electrical topology (how the elements that conform the circuits are interconnected) in terms of mathematical properties derived from the structure of their models.

In this sense, at what extent the topology by itself defines the dynamic behavior of the systems is explained.

The study is based on the graph theory allowing capturing, departing from the well-known Kirchhoff laws, the topology of the circuits into several matrices with specific structure.

The algebraic analysis of these matrices permits identifying conditions that determine whether the system is stable in the sense of Lyapunov and the kind of steady-state behavior that it exhibits.

The approach is mainly focused on typical topologies widely used in practice, namely, radial, ring, and mesh networks.
