Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0040] Wireless energy transmission is an effective alternative to the application of wired energy transmission in the range of impossibility, impossibility and inadaptability. When performing energy or power transmission between spacecraft, wireless energy transmission is more secure, flexible and It has obvious advantages in on-orbit operation and other aspects, especially suitable for docking scenarios between spacecraft power systems, and can effectively solve the requirements of high docking accuracy for wired docking during spacecraft rendezvous and docking. High risk of arcing. There are many ways to realize near-field wireless energy transmission, such as electromagnetic induction, magnetic resonance, microwave, electric field coupling, etc. The present invention proposes a wireless energy transmission between spacecraft based on near-...
