摘　　要：在无线电能传输系统中,信号无线传输同样重要。仅用一套线圈就实现电能与信号无线传输(即无线电能与信号同步传输)是无线电能传输技术产业化必须解决的首要问题,也是当前无线电能传输技术研究的热点问题之一。在四线圈结构的磁耦合谐振式无线电能传输系统基础上,结合移幅键控(ASK)调制与解调方式,提出一种新型的无线电能与信号同步传输方法,并设计其调制、解调电路和同步传输线圈。最后搭建相关的实验系统验证了所提同步传输方法的可行性和有效性。In the wireless power transmission application systems,the signal transmission is important.However,the synchronous transmission of power and signal by the same coil is the primary problem for applying the wireless transmission technology in industry.It is also one of the hot topics of wireless power transmission technology.Aiming at solving this problem,a power and information synchronous transmission method was presented using amplitude shift keying(ASK)modulation and demodulation based on wireless power transmission with four-coil structure.Then the circuits for modulation and demodulation as well as synchronous transmission coil were designed.Finally,the experimental results have verified the proposed method.
