abstract = "This article analyses the main candidate topologies for power
supply for low earth orbit satellite applications, which are
considered from the standpoint of energy continuity and power
balance. The system components are dealt with as energy port
elements through which energy is exchanged along the system. A
comparative study and selection of the optimal topology were
carried out, according to a criteria of mass/volume reduction and
system efficiency improvement. The comparison was made between a
three-domain controlled (fully regulated) and a two-domain
controlled (also called hybrid) bus topology. After selection, a
description of the design of the system control was given,
considering the battery charge regulator (BCR) and battery
discharge regulator (BDR) as a unified battery power conditioning
equipment integrated into a single bidirectional converter. The
system design was validated with a Simulink based model with the
selected topology being controlled in closed loop to provide a
regulated 28 V primary power bus. Finally, the article presents
the current prototyping under development.",
