An Efficient and Highly Coupled Energy Transfer Coil Optimization Design Method Applied to Space Wireless Energy Transfer System

In response to the demand for long service life and high reliability of power supply systems for future space multifunctional modular spacecraft, non-contact wireless energy transfer (WPT) technology can be used for power supply to avoid mechanical wear and arcing of cable interfaces. When wireless energy transmission occurs over a wide range of space, the coupling coefficient of the coupling mechanism in the wireless energy transmission system will decrease. This paper proposes an efficient and highly coupled energy transmission coil optimization design method applied to space wireless energy transmission systems. The coil optimization design method is studied to achieve efficient wireless energy transmission in high aspect ratio scenarios.
