针对感应耦合电能传输(ICPT)系统电能与信号同步传输方法中信号反向传输的优化问题,在深入分析已有文献的基础上,采用信号并联注入、串联拾取的能量信号反向同步传输拓扑,并提出其参数设计方法。该拓扑充分将ICPT系统的谐振电感考虑到载波信号发射电路中,增强信号发射强度;通过LC谐振回路的选频滤波及放大作用提升信号接收强度;同时,基于交流阻抗分析法对拓扑参数进行了建模分析和优化设计。最后,通过仿真和实验验证了拓扑及参数设计方法的可靠性与有效性。

Aimed at the signal reverse transmission optimization problem of power and signal synchronous transmission for the inductively coupled power transfer（ICPT）system,on the basis of exhaustive analysis of the existing literatures,this paper proposes a topology of power and signal reverse synchronous transmission realized by signal parallel injection and serial pickup,and the design method of corresponding parameters is presented.The resonant inductance of ICPT system is considered in the transmission circuit of carrier signal,which can enhance signal emission intensity.And the signal reception intensity is enhanced by the frequency selection smoothing and the current amplification of the LC resonant circuit.The modeling analysis and optimal design of topology parameteres are carried out based on the AC impedance analysis method.Finally,the reliability and validity of the proposed topology and parameter design method have been verified by the simulation and experimental results.
