摘　　要：针对感应耦合式无线电能传输系统的信号反向同步传输问题,提出一种通过控制整流器工作状态实现幅移键控信号调制控制策略。该方法不改变系统谐振网络拓扑结构,利用待传输信号控制副边整流器工作状态进行信号调制,通过检测原边电压包络形状得到解调信号。基于反射阻抗法分析副边电路的改变对原边电流影响。制作实验样机,实验结果表明该电路能够实现无线电能与信号反向同步传输,验证了方法的有效性。Aiming at the problem of signal reverse synchronous transmission of induction coupled wireless power transmission system, a modulation control strategy of amplitude shift keying signal is proposed by controlling the working state of the rectifier. This method does not change the topology of the system resonance network. It uses the signal to be transmitted to control the working state of the secondary-side rectifier for signal modulation, and obtains the demodulated signal by detecting the envelope shape of the primary voltage. The influence of the change of the secondary circuit on the primary current is analyzed based on the reflection impedance method. Finally, an experimental prototype is made. The experimental results show that this circuit can realize the reverse synchronous transmission of wireless power and signal, and verify the effectiveness of the method.
