                         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.",
