AMAYA, IVÁN; CRUZ, JORGE  e  CORREA, RODRIGO. SOLUTION OF THE MATHEMATICAL MODEL OF A NONLINEAR DIRECT CURRENT CIRCUIT USING PARTICLE SWARM OPTIMIZATION. Dyna rev.fac.nac.minas [online]. 2012, vol.79, n.172, pp.77-84. ISSN 0012-7353.

This article describes a numeric strategy focused on the solution of nonlinear systems of equations, frequently found in the analysis of electronic circuits. This strategy is based on the use of the particle swarm optimization (PSO) algorithm, as an alternative to the traditional Newton-Raphson. First, and as a demonstrative example, a circuit composed of two resistors and a diode were considered. Afterwards, a more complex one comprising one current source, four resistors, and two diodes was implemented. Based on the results, it was observed that the solution alternative is very attractive for solving these kinds of circuits, regardless of their size and complexity.
