摘　　要：无线电能与信号同时传输技术能够实现系统原副边间的信息交互。利用原边逆变电路的谐波特性,提出了一种基于零-串补偿的无线电能与信号同时传输技术,系统原边不设置补偿电容以在发射线圈中获得非正弦电流,利用非正弦电流中的基波分量进行能量传输,谐波分量实现信号传输。实验结果表明,该技术在不影响能量传输的前提下,有效减小了系统的体积和减少了成本,并较好地实现了信号的快速、准确传输。The simultaneous transmission technology between wireless power and signals can realize information interaction between the primary and secondary sides.This paper,through employing the harmonic characteristics of the primary-side inverter,puts forward the simultaneous transmission technology between wireless power and signals based on the zero-series compensation.First,the compensation capacitor is not set in the primary-side system to obtain a non-sinusoidal current in the transmitting coil.Then,the fundamental component of the current is used to transmit power,and the harmonic content realizes signal transmission.The experimental results show that this technology can effectively reduce the volume and cost,and realize the fast and accurate signal transmission without affecting the power transmission.
