Parameter evaluation of the equation of the electrostatic discharge current using genetic algorithms as optimization tool

The scope of this paper is the parameter evaluation of equations that possibly can describe the current during an electrostatic discharge, using genetic algorithms. It is necessary to find an equation for the electrostatic discharge current, because there are aberrations among simulations and the waveform described in the IEC 61000-4-2 standard. In this work the genetic algorithm has been applied on the parameters of four equations. The genetic algorithm has as input data real measurements of the discharge current produced by an electrostatic discharge generator and, using these data, optimizes the parameters of the mathematical equations. The comparison between the experimental and the optimized data proves the efficiency of the genetic algorithm and the most suitable equation among the four for the discharge current derives
