Study of an Ultra Modular Power Supply for a Low Earth Orbit Satellite
Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
Power supply is a major component of a satellite subsystem, without it the whole system will not work. In general, production and management of energy are critical to a spacecraft and because of this aspect development of a new system is a long and tedious process, usually taking more than six years to complete. With this study a faster and cheaper way of building a power supply from multiple predesigned modules is researched. More specifically the study focuses at first on the algorithm that controls one power module. After having a fully working power module the objective is to implement a similar algorithm on multiple power modules, validating the whole modular concept. In this study various elements from control theory are implemented and simulated and based on the results, the final variant is chosen. This variant will be tested on a hardware platform designed by another intern working on the same project. Towards the end of the study, multiple module case will be considered and an algorithm approach will be defined for further studies. This will include the selection of a communication protocol that will be needed for multiple units to work together and a small study into various upgrades of the algorithm depending on various situations.
