Solar Module Integrated Converters as Power Generator in Small Spacecrafts: Design and Verification Approach

Abstract

As small satellites are becoming more widespread for new businesses and applications, the development time, failure rate and cost of the spacecraft must be reduced. One of the systems with the highest cost and the most frequent failure in the satellite is the Electrical Power System (EPS). One approach to achieve rapid development times while reducing the cost and failure rate is using scalable modules. We propose a solar module integrated converter (SMIC) and its verification process as a key component for power generation in EPS. SMIC integrates the solar array, its regulators and the telemetry acquisition unit. This paper details the design and verification process of the SMIC and presents the in-orbit results of 12 SMICs used in Ten-Koh satellite, which was developed in less than 1.5 years. The in-orbit data received since the launch reveal that solar module withstands not only the launching environment of H-IIA rocket but also more than 1500 orbits in LEO. The modular approach allowed the design, implementation and qualification of only one module, followed by manufacturing and integration of 12 subsequent flight units. The approach with the solar module can be followed in other components of the EPS such as battery and power regulators.

Verification Approaches for Nano- and Micro-Satellites

“…Piedra, Torres, and Ledesma [11] explore the viability, from a thermal point of view, of a composite material with ZnO nanoparticles to be employed in lieu of aluminum for the primary structure of a CubeSat, by performing finite element thermal analysis. After recognizing scalability as an effective approach towards rapid subsystems development times, while reducing the cost and failure rate, Gonzalez-Llorente et al [12] present a modular approach for the power generation within micro-satellites, called the Solar Module Integrated Converter (SMIC), using the Ten-Koh micro-satellite as a testbed to prove this concept.…”

Launch Environment Ground Test Evaluation with Multi-axis Vibration and Shock for Pouch Solid-State-Ceramic Battery Advanced Energy Storage

“…The performance of the jig has been checked with simulation for the three-axis and different modes using Solidworks software to confirm its ability to waistband the test conditions safely. Since the solid-state-ceramic batteries are planned to be launched on the same rocket as Ten-Koh satellite, the Japanese rocket H2A [18], [19], the same approach for the launch conditions previously adopted by Jesus Gonzalez for the solar modules integrated converters [20], as well as the Lithium-Ion battery pack for the Ten-Koh satellite and all its subsystems [21], [22], have been reproduced as the input's requirements for the launch environment ground test. Two different test facilities have been selected to satisfy the test conditions.…”
