Acesso em:.https://bdm.ufpa.br/jspui/handle/prefix/6874The mission called Super Time Brazilian Satellite Olympics 01 (ST-OBSAT-01) aims to launch a 1U CubeSat, i.e., with dimensions of 10 x 10 x 10 cm, in the year 2024. The goal is to design a low-cost satellite by leveraging commercially available components. This work is focused on the development of the Electrical Power System (EPS) of the ST-OBSAT-01 satellite, which comprises an energy acquisition, storage, distribution, and monitoring system. Additionally, the EPS must meet mission requirements in various aspects, such as standardization, connections with other subsystems, operational requirements, power consumption, among others. This thesis describes the design, analysis, implementation, and testing of an EPS module, which is a essential part of the satellite. The developed EPS has input for up to six solar panels, interconnected to the rest of the system through three parallel DC-DC boost converters incorporating a Maximum Power Point Tracking (MPPT) algorithm. A centralized EPS architecture was adopted. Buck- boost DC-DC converters provide regulated outputs at 3.3 V and 5 V to the satellite’s other systems. The regulated outputs are distributed from an unregulated central bus connected to a rechargeable 4.2 V Li-ion battery. The EPS also incorporates load protection circuits, safety switches, and a microcontroller capable of managing, monitoring, and providing telemetry data from the EPS to the satellite’s On-Board Computer (OBC). The final product of this work is a module composed of two Printed Circuit Boards (PCBs), which together form the EPS. The module’s functionality was tested, and the results were properly documented. The tests ranged from visual inspections to integration, electrical measurements, and telemetry system data acquisition. During the testing process, points requiring correction, enhancement, and improvements were identified. Overall, the module demonstrated good performance, aligning with most of the initial project expectations. All relevant documentation for module fabrication, design, programming codes, and future updates has been made available on GitHub.Acesso AbertoCubeSatConversores DC-DCEPSPCBOlimpíada Brasileira de SatélitesDC-DC convertersBrazilian Satellite OlympicsCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::SISTEMAS ELETRICOS DE POTENCIACNPQ::ENGENHARIAS::ENGENHARIA AEROESPACIAL::SISTEMAS AEROESPACIAIS::SATELITES E OUTROS DISPOSITIVOS AEROESPACIAISTrabalho de Curso - Graduação - Monografia
