A Projective-Based Formalism for Symmetric Modeling of Electrical Circuits

We survey in this contribution some recent ideas involving the use of a homogeneous formalism to set up electrical circuit models. Broadly, the goal is to avoid any lack of generality in the modeling process by avoiding unnecessarily restrictive assumptions in the form of the characteristics of the circuit devices. We discuss how to use this approach in the framework of nodal analysis, aiming at the development of computationally efficient models. Except for some minor technicalities arising in the index analysis, the discussion is deliberately kept at a simple level.
