磁耦合谐振式无线电能传输技术研究进展

摘要

As a mean of wireless power transmission (WPT), magnetic coupling resonant wireless power transmission distance can be from scores of centimeters to several meters, transmission efficiency can reach 90%, and transmission power can reach kilowatt grade. Study was carried out for whole structure category of magnetic coupling resonant WPT system, topologic structure category of resonator, improvement of transmis-sion distance, transmission efficiency and transmission power methods and resonant frequency split etc aspects. Summary was made for study results of related colleges and universities at home and the application prospect of the technology and existing problems was given.%　　作为一种无线电能传输(WPT)方式，磁耦合谐振式无线电能传输距离为几十厘米，传输效率可以达到90%，传输功率可以达到千瓦级。对磁耦合谐振式 WPT 系统的整体结构类型，谐振器的拓扑结构类型，提高传输距离、传输效率和传输功率的方法及谐振频率分裂等几方面进行了研究。总结了国内相关高校的研究成果，并给出了该技术的应用前景及存在问题。
