                         Power Subsystem (EPS) of an artificial satellite are to generate, 
                         store and supply the necessary energy to the payloads, by 
                         regulating, controlling and distributing the energy generated by 
                         the solar panels and stored by the batteries. Choosing an 
                         efficient EPS topology and an effective power management control 
                         are crucial elements for mission success and long satellite life. 
                         Early in their design, it is important to verify the compliance of 
                         some requirements, especially on efficiency, via Models and 
                         Simulations (M\&S) of the solar panels, batteries and converters, 
                         and the analysis of their results. So, this work presents the 
                         comparative study, according to an efficiency criterion, 
                         evaluating the system overall efficiency, for two classes of 
                         topologies: Direct Energy Transfer (DET) and Peak Power Tracking 
                         (PPT), in unregulated bus, of Electrical Power Subsystems for 
                         artificial satellites, by comparing the energy dissipated for each 
                         of them along the orbital period via modeling, simulation and 
                         analysis. The results obtained so far suggest that: 1) PPT 
                         topology is more efficient than DET topology; 2) the adopted M\&S 
                         and the analysis performed validate them as a tool to assess the 
                         EPS efficiency requirement.",
