Abstract

RESUMEN

En este artículo se diseña un cargador de baterías para aplicaciones aisladas alimentado con energía solar fotovoltaica, se utiliza un convertidor DC-DC reductor y paneles solares con potencia nominal de 100W. En el sistema de control es aplicado un algoritmo de seguimiento del punto de máxima potencia llamado perturbar y observar con el fin de extraer la máxima potencia disponible en el panel solar utilizando un modulador PWM que controla la corriente de salida en el panel solar. Los elementos pasivos del convertidor son calculados para operar en el modo de conducción continua, el sistema de control utiliza un dsPIC30F4011, y su funcionamiento es comprobado experimentalmente.

Palabras clave: Convertidor reductor, cargador de baterías, energía solar, seguimiento del punto de máxima potencia.

ABSTRACT

This article addresses the design of a battery charger for off-grid applications powered by photovoltaic solar energy, using a DC-DC buck converter and solar panels with nominal power of 100W. In the control system a perturb and observe (P&O) maximum power point tracking algorithm is applied aiming of operating at the optimum point, using a PWM modulator which controls the output current of the solar panel. The passive elements of the converter are calculated to operate in a continuous conduction mode. The control system uses a dsPIC30F4011, and its performance experimentally verified.

Keywords: Buck converter, battery charger, solar energy, maximum power point tracking.
