                         (Distributed Power System - DPS), utilizando para isso o conceito 
                         de conversores CC-CC empilhados. A topologia proposta garante que 
                         o rastreamento do pico de pot{\^e}ncia (Maximum Power Point

                         Power Subsystem (EPS) for pico-satellites is a set of hardware and 
                         software that supplies energy demands throughout the lifetime of 
                         the satellite. There are several classifications for EPS 
                         architectures. This work presents an analysis and general 
                         discussion of the main EPS architectures for CubeSats and a new 
                         architecture based on the Distributed Energy System (DPS) using 
                         the concept of stacked DCDC converters. The proposed topology 
                         ensures that maximum power point tracking (MPPT) is performed 
                         concomitantly with the bus voltage regulation. With this, the 
                         energy destined for the DC bus is processed only once from the 
                         photovoltaic array. In addition, due to the parallel connection of 
                         the input, this architecture allows the redirection of energy to 
                         the battery, reducing the time of charge and ensuring that the 
                         battery will be fully charged during the eclipse intervals of the 
                         satellite. Also, the experimental results that prove the operation 
                         of the proposed architecture will be presented.",
