A New Converter for Common Mode Noise Reduction for EPS of a Nano satellite

The Small Satellite (SmallSat) industry has recorded incredible growth recently. Within this class, among Mini-, Micro-, and Nanosatellites, the Cube Satellite (CubeSat) is primed for an explosion of growth. These satellites are fascinating for remote sensing, earth observation, and scientific applications. Remarkable attention from the space operators makes it valuable because of its low cost, cubic shape, less manufacturing time, lightweight, and modular structure. Among the various subsystems comprising the SmallSat, the Electrical Power System (EPS) is the most crucial one because unreliable power supply to the rest is most of the time detrimental to the mission. The EPS is formed by electrical sources, storage units, and loads, all interconnected via different power converters, the operation of which must be closely orchestrated to accomplish efficient use of photovoltaic power, optimal battery management, and resilient power delivery. At the same time, the EPS design must address a series of challenges such as size restrictions, high power density, harsh space environments (e.g., atomic oxygen, radiation, and extreme temperatures) which significantly impact the EPS electrical and electronic equipment. In terms of power systems, a SmallSat EPS can be considered a space microgrid owing coordination and control of distributed generation (DG), storage and loads in a small-scale electrical network. From this point of view, this paper reviews and explores SmallSat microgrid's research developments, energy transfer and architectures, converter topologies, latest technologies, main challenges, and some potential solutions which will enable building a more robust, resilient, and efficient EPS. The research gaps and future developments are underlined before the paper is concluded.

“…The power control stage in small satellites is classified into two types: direct energy transfer (DET) circuits and peak power transfer (PPT) topologies, which are based on an unregulated or regulated bus voltage [7,8]. The EPS architecture used in nanosatellite based on DET are dissipative methods and without the capability of tracking the maximum power [9]. The DET circuit is the source of theoretically higher losses at the filtering components and dissipative circuit.…”

This paper is aimed at performing a comprehensive review of the approaches employed in nanosatellite platforms, specifically 1 U and 3 U, for electrical power systems (EPS). Moreover, it seeks to develop a robust maximum power point tracking (MPPT) controller using the sliding mode control (SMC) method. The proposed control strategy is intended to monitor the solar panel’s maximum power point (MPP) and adapt to changes in temperatures and solar irradiance in low Earth orbit (LEO). The EPS model, designed with the proposed sizing method, is built in MATLAB-Simulink and integrates a solar panel, battery storage, and power converters controlled by diverse MPPT methods. Then, simulation results demonstrate the effectiveness of the proposed SMC approach compared to other conventional control methods for the designed EPS under varying LEO conditions. To achieve a robust validation of the most appropriate MPPT control method under steady-state conditions, this paper presents an experimental investigation into the proposed EPS hardware design. The proposed SMC method achieved an increase in power generation from 10% to 12% for buck and boost power converters, respectively, compared to traditional control methods.

“…However, for very high step-up or step-down conversion ratios, some limitations arise, and other approaches are required [13]. Buck [14] and boost [15] derived topologies are the most common, but also SEPIC [16] and other advanced topologies can be found [17].…”

This work presents a single point failure free solar array regulator design for scientific deep space exploration micro-satellites, where reliability and fault tolerance are critical design aspects. The proposed regulator is composed by six independent dc/dc Buck converters controlled by a double control loop, which can control both the battery end-of-charge voltage if the battery is fully charged, or the power generated by the solar arrays otherwise. Besides, to optimize the extracted power, each phase has an analog maximum power point tracker circuit. In addition, the regulator has a redundant over voltage protection circuit that switches off the converters in case of battery overvoltage. Furthermore, this regulator is tolerant to the failure of any component. This paper describes the electronic design of the regulator, including a detailed system stability study, as well as the implementation of a 60W prototype and the tests that have been carried out to validate the design. The main contributions of this paper are: A practical solution for a solar array regulator for space applications is proposed; a detailed stability study is developed; a overvoltage protection circuit is presented; a prototype has been implemented using commercial off-the-shelf (COTS) components with space qualified equivalent versions; and extensive functional tests have been carried out under different space representative conditions to validate fault tolerance and robustness.INDEX TERMS Fault-tolerant regulator, maximum power point tracker (MPPT), microsatellite power system, solar array regulator.
