摘　　要：近年来,无线电能传输技术成为国内外研究的热点,随着这一技术在各领域的推广,其应用的电磁环境也日趋复杂。文章针对多套无线电能传输系统近距离同时工作的情况,分析相邻系统对本系统能量传输效率的影响因素,其次通过仿真分析多组系统同时工作时系统参数和空间电磁场分布的变化,最后通过实验验证仿真结果,当多组无线电能传输系统近距离工作时,系统谐振器与相邻系统的谐振器存在电磁耦合现象,进而改变了谐振器多项参数,引起系统谐振点偏移,导致传输效率的降低。Wireless power transmission has become a popular topic in recent years. Along with the fast development of the technology in various fields, the electromagnetic environment is getting complicated. This paper focuses on the interaction that comes from adjacent devices when several equipments work simultaneously in relatively small rooms. The system parameters and distribution of electric-magnetic fields are indicated by finite element emulation software. At last, the experiments confirmed that a set of system resonators has electromagnetic coupling with adjacent ones and a series of resonator parameters are changed, which causes resonance point deviation and reduces transfer efficiency.
