Abstract
Maximizing solar energy harvesting and miniaturizing DC-to-DC converters will be a difficult task for the CubeSat that operates in low earth orbit (LEO), where size and weight are limited. To maximize solar energy collection, the electrical power system (EPS) architectures use numerous separate DC–DC converters, which will be problem for miniaturization of whole model because several inductors will be used in each converter. The key purpose of this article is to demonstrate a topology of multiport converter that requires only one inductor and a small number of components, reducing the overall system size. The proposed system will have half-bridge modules with series connection, connected parallelly with PV panels will power the battery system through a DC-DC boost converter. On considering the 1U CubeSat standards a prototype is used to verify the performance of the proposed converter in numerous case scenarios.
