Design of spacecraft multi-channel near-field wireless energy transfer system

For the non-cable requirement in space rendezvous and docking, spacecraft power distribution, and on-orbit service and maintenance, the multi-channel near-field wireless energy transmission system is proposed. The multi-channel magnetic coupling near-field wireless energy transmission mathematical model is established, the important parameters that affect the transmission efficiency of the system are analyzed, and the simulation analysis of the influence of key parameters on system efficiency is carried out. Through the efficient coupling design of the coil, the efficiency of the near-field wireless energy transmission system is optimized. The multi-channel near-field wireless energy transmission system proposed in this paper solves the problem of wireless transmission of energy and realization of multi-load reception. Finally, an experimental study was carried out on a 1 000 W multi-channel near-field wireless energy transmission prototype. The experimental results show that the proposed multi-channel near-field wireless transmission device has high transmission efficiency and solves the multi-load problem of spacecraft wireless energy transmission.
