Abstract: | Magnetic coupled wireless power transfer has the advantages of high efficiency, non-contact, and no exposed metal contacts, which has important application prospects for solving non-contact power supply in space. In order to promote the research and development of space magnetic coupled wireless power transfer related technologies and the transformation of achievements, this paper focuses on sorting out the development roadmap of space magnetic field coupled near-field wireless energy transmission technology in foreign countries, researching demonstration or technical demonstration projects that have been carried out in the past fifteen years, analyzing key technical solutions and indicators in foreign countries, and proposing development suggestions for prioritizing the use of induction coupled wireless energy transmission with distance of centimeter level between equipments within spacecraft, and resonant coupled wireless energy transmission with distance from tens of centimeters to meters level between spacecrafts, transmission power with the ability of above kilowatt, and transmission efficiency with above 85%, providing guidance for the future development of space magnetic field coupled near-field wireless energy transmission technology. |
