Research on Voltage Stabilization Technology for Long-distance Energy Transmission in Orbit

For large spacecraft such as space stations and spacecraft, due to their huge systems, when the power supply equipment and electrical equipment are remote away, it is necessary to lay a long power supply cable. Therefore, when high-power energy transmission is carried out, the voltage drop of the cable will cause the terminal voltage of the electrical equipment to fluctuate with the transmission power. This will have an impact on some load equipment with high demand for electricity, and even shorten the service life of the equipment. In order to ensure the stability of terminal voltage and controllable amplitude of fluctuation, this paper proposes a voltage stabilization technology for long-distance energy transmission in orbit, and the principle analysis, simulation, and experimental verification are carried out to confirm the effectiveness of the technology.
