En este artículo se presenta un modelado detallado de un conversor de CA/CC con capacidad de corregir el factor de potencia, representando los circuitos en los diferentes ciclos de operación. Inicialmente se obtienen las ecuaciones diferenciales y la representación en espacio de estados, para luego llegar a un modelo promediado. Con base en ese modelo se propone una ley de control para lograr un factor de potencia alto, la que se verifcó numéricamente usando la herramienta POWERSIM© de MATLAB®. Los resultados se analizaron siguiendo la norma IEC 61000-3-2.
This article presents a detailed model of an AC/DC converter with capacity to correct power factor, by representing the electrical circuits on the different operation cycles. First, the differential equations and states space models are obtained, then an averaged model. Based on this model a control law is proposed to achieve a high power factor correction, what was numerically verified by using POWERSIM© toolbox of MATLAB®. The results were analyzed by following the standard IEC 61000-3-2.
