Abstract
En la actualidad, gracias a los avances en técnicas de iluminación y a la reducción de costos en tecnologías de estado sólido, la implementación de sistemas de potencia para el control lumínico ha tomado lugar en el desarrollo de diversas aplicaciones orientadas al área de seguridad, agrícola, automotriz, y energías renovables.De esta forma, el objetivo principal del presente trabajo es el desarrollo de un circuito impreso PCB modular, capaz de controlar la intensidad lumínica de un LED de alta potencia través de la implementación de un convertidor dc-dc reductor sin capacitor. El propósito final del proyecto es generar una herramienta para el desarrollo de futuros estudios en áreas relacionadas a energías renovables, crecimientos de plantas e iluminación urbana.El desarrollo del presente trabajo comienza con el análisis y simulación de los componentes bases para el diseño del convertidor y características de control acorde a los requerimientos de un sistema que permita el encendido de un LED de alta potencia. Luego, se debe dimensionar y construir un circuito impreso (PCB) en base a los parámetros y estrategias de diseño definidos para generar un primer prototipo del proyecto. Una vez que haya sido verificado el funcionamiento del prototipo, se procederá a documentar bajo condiciones reales de operación el comportamiento del convertidor y se realizará una evaluación de posibles mejoras en base a los objetivos específicos perseguidos al inicio del trabajo.

The final purpose of the project is to generate a tool for the development of future studies in areas relates to renewable energy, plant growth and urban lighting.The development of this work starts with the analysis and simulation of the main components of the converter and control characteristics according to the requirements of a system that allows the lighting of a high-power LED. Then, a printed circuit (PCB) must be dimensioned and constructed based on parameters and design strategies to generate a first prototype of the project. Once the operation of the prototype has been verified, the behavior of the converter will be documented under real operating conditions and an evaluation of possible improvements will be made based on the specific objectives pursued at the beginning of this work.
