为了实现无线电力和信息传输(WPIT)，在传统的电感耦合电力传输(ICPT)系统中增加额外的信号传输线圈，导致结构复杂，增加了体积和成本。此外，电源和信号通道之间存在的串扰使得分析和设计变得困难。因此，针对单通道、双线圈ICPT系统提出了基于基波分量的WPIT技术，其中通过发射线圈中流动的三角电流的三次谐波分量来传输信号。分析了其工作机理、电路间串扰、信号检测通道参数选择原则，讨论了负载条件对谐波通信质量和信号传输对效率的影响。实验结果表明，该方法能够有效简化结构，减小体积和成本，从根本上简化系统的建模、分析和设计，并能实现高质量的电力和信息同步传输。
In order to realise wireless power and information transmission (WPIT), extra signal transmission coils are added in a traditional inductively coupled power transmission (ICPT) system, which results in a complicated structure and increases the volume and cost. Moreover, crosstalk existing between the power and signal channel makes it difficult to analyse and design. Therefore, WPIT technology based on the fundamental-harmonic component for a single-channel and two-coil ICPT system is proposed, in which the signal is transferred via the third harmonic component of the triangular current flowing in the transmitting coil. The working mechanism, crosstalk among circuits, parameter selection principle of signal detection channel are analysed, and the impact of load conditions on harmonic communication quality and that of signal transmission on efficiency are discussed. The experiment results show that the method can effectively simplify the structure, reduce the volume and cost, and fundamentally simplify the modelling, analysis, and design of the system, and high-quality power and information synchronous transmission can be achieved.
