Modular Power System and bus bar scheme in high power communication satellite

摘要

This paper elaborates implementation of new and advanced concepts such as Modular Power System and bus bar scheme for power distribution in ISRO's high power communication satellite. The advantages of using Modular Power System vs. conventional power packages, details of new design and realization of Modular Power System are discussed. New mechanical housings realized for high power communication satellite are described. Usage of bus bar for power distribution has many advantages (as compared to wired harness) such as, reduced power distribution loss, higher current carrying capability, improved EMC performance, better thermal management and scope for mass reduction.
