摘　　要：为解决目前感应耦合电能传输(ICPT)系统中能量与信号同步传输技术存在的多线圈结构复杂、传输信噪比低、线圈解耦困难和电路复杂等问题,提出一种基于LCL无功补偿网络的能量与信号同步传输方法。根据LCL-S型ICPT系统在品质因数较大时系统电压增益将存在2个极值点的特性提出一种采用调频调制方式实现能量与信号同步传输的方法,最后通过实验验证了理论研究的正确性与可实现性。In order to solve the problems of multi-coil structure,low signal-to-noise ratio,coil decoupling difficulty and circuit complexity in current inductive coupled power transfer(ICPT)system,a method of energy and signal synchronous transmission based on LCL reactive power compensation network was proposed.According to the characteristic that the voltage gain of LCL-S ICPT system will have two extreme points when the quality factor is large,a method of synchronous transmission of energy and signal using FM modulation was proposed.Finally,the correctness and feasibility of the theoretical research were verified by experiments.
