Estudio, diseño y simulación de cargador portátil de baterías para dispositivos de baja potencia mediante módulo fotovoltaico

Abstract

[ES] En el presente trabajo se realiza el diseño, estudio y simulación de un prototipo de cargador solar de baterías portátil de baja potencia para pequeños aparatos electrónicos haciendo uso de la energía renovable del sol como única fuente de energía. Para el desarrollo del proyecto será necesario implementar el modelo del módulo fotovoltaico en cuestión, seguido de un seguidor de punto de máxima potencia y un convertidor DC-DC con su respectivo control que establecerá un voltaje de salida de 5V. El convertidor diseñado en este caso será un reductor BUCK. Los programas informáticos utilizados para el desarrollo del proyecto serán Matlab-Simulink en lo que respecta a la simulación y Mathcad para los cálculos teóricos y estudios previos.

[EN] Throughout this paper, we will study both the design and simulation of a prototype low power portable solar charger that could be used for batteries of small electronic devices such as mobiles, laptops, powerbanks, tablets, music players … Making use of the renewable energy of the sun as the only source of energy, without needing to depend on the connection to the electricity grid in case you need to recharge these devices mentioned above. In order to make the development of this prototype in question possible, it is necessary to implement the model of a photovoltaic solar module, an MPPT tracker and as a last stage, and to achieve a constant output voltage, it will be necessary to have a DC converter -DC that sets an output voltage of 5V, which is the standard USB charging method. The converter designed will be a voltage reducer from direct current to direct current, to BUCK. The software (software) that you will need for the development of the project that concerns us mainly in two: Matlab-Simulink for the simulation and Mathcad for the technical calculations and studies prior to it. The use of both programs is developed throughout the career in the different subjects of Power Electronics or Automatic, so it will be familiar to its use
