摘要
为解决谐振式无线电能传输系统中存在信号传递问题,提出一种基于载波的数字信号传递方法。通过耦合模理论对系统建模,对电能与信号同步传输特性和效率进行分析。使用可调稳压电路对发射端电压调幅调制,拾取端借助耦合机构对能量进行收集,并利用电压比较电路对信号复原。结果表明:在不更改谐振式无线电能传输系统拓扑结构的条件下实现携能通信,组建实验平台验证本文方法的有效性。
In order to solve the problem of signal transmission of the resonant wireless power transfer system,a digital signal transfer method based on the carrier wave is proposed. The mutual inductance theory was used to investigate the system of a model,expound the principle of signal transmission,and analyze the synchronous transmission characteristics and efficiency of electric power and signal. The voltage amplitude modulation at the transmitting terminal is modulated by the adjustable voltage stabilizer circuit,the power is collected by the coupling mechanism at the pick-up end,and the signal is recovered by the voltage comparison circuit. The results show that the method is validated by establishing an experimental platform for carrying energy communication of changing the topology structure of the resonant wireless power transfer system. It is concluded that the proposed method is effective.
