resultados sugerem que: 1) a topologia PPT {\'e} mais eficiente

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.",
