Abstract

In this work, the modelling of a non-isolated Photovoltaic (PV) Energy Power Source (EPS) for a 3U CubeSat miniaturized satellite is presented. The power source is composed by two PV arrays with multiple DC-DC converters, responsible for the control of electrical variables in the power unit.Maximum power extraction from solar panels and charge/discharge of a battery pack are tested based on dynamic profiles proposed in the context of IFEC 2020. Finally, a wide range of load variations was applied in order to test the correct operation of the EPS.
