MPPT and SEPIC based controller development for energy utilisation in cubesats
Abstract
Cubesats fall in the line of miniature satellites that imparts nano technology in them. They are very compact in size of about 1000 cm3. A cubesat consists of Power Supply Unit (PSU), On Board Computer (OBC), Altitude Determination and Control System (ADCS), Communication System (COM), Camera (CAM) or the payload and other structural subsystem. In our paper we are in focus of the Electrical Power Supply Unit (EPS) that is responsible for the power transfer to the rest of the system. The PSU consist of solar panel, electronics and batteries. The objective of the paper is to design the controller circuit to track maximum power from the source. The conventional buck converter is replaced with the buck-boost converter which can be used for both as the step up and step down converter. Hence the MATLAB design of Maximum Peak Power Tracking in combination with the SEPIC converter is discussed further along with the proposed block diagram.

By calculating the open-circuit voltage and the short-circuit current, the degradation curves show an accuracy of 5%, which is a good agreement with experimental data.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
