Abstract: In this study, we present a piecewise-linear appraoch in order to construct a DC model of a voltage regulator which will approximate the external behaviour of the the original circuit. The main goal behind the use of this technique is to solve the non-linear behaviour problem encountred with analogue circuits and to give a simplified description of their complexity. In fact, the model obtained from experimental work corresponds to a two port equivalent circuit whose elements are linear such as resistors, controlled and independent voltage sources. Their values are extracted from measured terminal characteristics by applying that approach over all the operating regions. Simple mathematical equations are joined to the model in order to ease a computer analysis.
