A CubeSat is a miniature satellite designed for space science. Due to its low cost and small size, not only has it earned a high position in the field of space exploration but it has also become a reliable tool for space education. CubeSats are powered by solar panels mounted on each side of the cube. It is essential to maximize the available electrical energy gained from the minimal solar panel area available. This paper primarily focuses on the Electric Power Supply (EPS) that is responsible for supplying power to the system. A prototype EPS is constructed using a SEPlC to regulate battery voltage as well as the voltage at the loads. Maximum Power Point Tracking (MPPT) using the optimal duty ratio of the DCIDC converter is employed in order to obtain the maximum power from the solar panels.

“…The gallium nitride field effect transistors with enhancement mode like LMG5200 integrated drivers can be used for HB modules. These devices were chosen because GaN devices run at high frequencies can minimize the values of filter components and hence size get reduced and better controlling of converters can also be provide [9], but the IRF 540N was chosen because it is less expensive to produce the prototype. The output of half bridge circuit is fed to a boost converter (to boost up the solar output which can power the high voltage payloads) and to a battery storage system (to store energy which will be useful in time of no solar irradiation) and to 3.3V and 5V regulators to power the low voltage payloads.…”

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.

“…In [37], the design of a Buck-Boost converter with a PI controller is used in order to combine both hybrid power sources PV/Wind with a battery storage system. In [38], a PID controller is used for BCR with a conventional MPPT algorithm for the optimization of the power extraction. In [39], a Sliding Mode Control (SMC) strategy was used for the MPPT and the control of the battery voltage.…”

One of the most critical systems of any satellite is the Electrical Power System (EPS) and without any available energy, the satellite would simply stop to function. Therefore, the presented research within this paper investigates the areas relating to the satellite EPS with the main focus towards the CubeSat platform. In this paper, an appropriate EPS architecture with the suitable control policy for CubeSat missions is proposed. The suggested control strategy combines two methods, the Maximum Power Point Tracking (MPPT) and the Battery Charge Regulation (BCR), in one power converter circuit, in order to extract the maximum power of the Photovoltaic (PV) system and regulate the battery voltage from overcharging. This proposed combined control technique is using a Fuzzy Logic Control (FLC) strategy serving two main purposes, the MPPT and BCR. Without an additional battery charger circuit and without switching technique between the two controllers, there are no switching losses and the efficiency of the charging characteristic can be increased by selecting this proposed combined FLC. By testing a space-based PV model with the proposed EPS architecture, some simulation results are compared to demonstrate the superiority of the proposed control strategy over the conventional strategies such as Perturb and Observe (P&O) and FLC with a Proportional Integral Derivative (PID) controller.
