Buck Converter and SEPIC Based Electronic Power Supply Design with MPPT and Voltage Regulation for Small Satellite Applications
Abstract
This paper presents the proposed power distribution system designed for the power management of the Puerto Rico CubeSat. Power is provided to the CubeSat using Gallium Arsenide (GaAs) solar panels mounted on each side of the satellite. It is vital to maximize the available electrical energy obtained from the minimal solar cell area available. SEPIC topology performs the Maximum Power Point Tracking (MPPT) to extract the utmost available power from the solar panels. The Buck converter is used to provide voltage regulation for the CubeSat payloads. The power distribution for the CubeSat is designed for higher efficiency, utilizing high-performance GaAs solar panels and DC/DC converters in combination with a MPPT technique to improve the power extraction and further increase efficiency.

Supercapacitors (SC) or ultracapacitors can be considered an alternative ESS for small satellites because of their high-power density, long charge/discharge life, and operation in wider temperature ranges.

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.
