Design and Implementation of Power Distribution Module of Low Earth Orbit Small Satellite
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2017, Vol 12, Issue 3
Abstract
Power distribution system is a vital system and considered as one of the most important subsystem of the whole satellite. This paper basically discusses the design of the power distribution module (PDM) of a low earth orbit small satellite. The designed PDM draws24 Volt unregulated power from the Power Control Distribution Unit battery charge regulator module (PCDU-BCR)and then provides regulated 3.3 Volt, 5 Volt, 12 Volt and unregulated 24 Volt to the satellite subsystems. The PDM implements current sensing, current limiting, switching and protection of the loads.Moreover the PDM design fulfils internal redundancy to achieve the required reliability.The switching algorithms are built to control the loads' operation during the satellite different modes of operation through the PDM design configuration.The design of the PDM is based on the Commercial Off the shelf Components (COTS) that is cost efficacious. Therefore this paper is valuable in building of the small satellites' Electrical Power Systems (EPS) that are low cost but highly efficient. The satellite mission input requirements for EPS are verified by the output results of the implemented PDM.
