AbstractOUFTI-1 is a picosatellite developed by students at the University of Liège (ULg). Thegoal of the OUFTI project is to provide a hands-on satellite experience to students. Thesubject of the present thesis is the design and implementation of the electrical power system(EPS) of OUFTI-1. The EPS role is to supply other systems of the satellite with appropriateelectrical power. First, the requirements of the EPS are defined. The architecture of the EPSis then designed. When the architecture is known, we verify that the consumed power onboard does not exceed the produced power. The electrical design of the different modules ofthe EPS is carried out. Finally, the prototypes of the EPS are presented.Keywords: OUFTI-1, CubeSat, LEODIUM, Electrical power system.
