Sistema de gestão de energia para pico-balões de alta altitude

Abstract

This monograph aims to present the development of the energy management system project for high altitude pico-balloons, more specifically the project capable of generating enough energy of 245.03 mW of power in order to feed the electronic components of the high-altitude pico-balloon tracker that is being developed by the radio club through the Minuano Project. The document presents results of maximum power of seven arrangements of solar cells for a given load, of tests of solar cells connected to a DC-DC converter, of the creation of three functional PCIs of two DC-DC converters and presentation of the methodology used to obtain the results, and the tests were carried out at the Federal University of Pampa, in the laboratory of the Computer Architecture and Microelectronics Group (GAMA). For validation and testing of the methodology, three systems were created with the TPS61097A and TPS61200 converters. In which they are composed of sets of solar cells in series and/or parallel connected to the converters mentioned above. Of these three systems, the one with the TPS61200 converter reached 3.28 V and 284.6 mW for an input power of 338.6 mW, thus having 84.05% efficiency.
