Abstract:

This study is based on the results obtained in a final project in 2004, carried on at the Escuela de Ingenieros Industriales de Albacete (Universidad de Castilla-La Mancha, Spain) tutored by one of the authors of this contribution. The objective of this paper is to use, modify and extend some of the scripts made in MATLAB, adapting them to the latest versions of this software as well as include some improvements and new features not initially considered.

The scope of application of the tool developed is for students of Industrial Engineering Degree, in the specialities of Electricity and Electronics. Specifically, it is focused on the field of resolution of electrical circuits symbolically, because there is the interest in the aspect of being able to solve problems where some element has no previous value assigned and trying to obtain analytical expressions for various magnitudes like voltages, currents, powers, etc. It will be necessary to know the applications of Laplace Transform, for symbolic resolution and the Inverse Transform to return to the time domain.

The theoretical core used for the circuit resolution method is the method of loops-branches, so it is briefly indicate the process for resolving a circuit, without going into details (except those concerning the syntax of the tool).

At the moment, it have been developed some MATLAB scripts, which allow simulations to analyse a wide range of circuits, relatively easily. It is hoped to continue in that line, expanding the range of possibilities in this area: Stationary Sinusoidal Regime (RES), harmonics study, quadrupole, frequency response, symmetrical components, etc.
