传统的有线充电方式有许多缺点,如机械老化、漏电和占用空间等,无线充电方式可以解决上述问题,具有良好的实用性和发展前景。本文基于电磁感应和等效电路理论,建立串并型双共振无线充电系统仿真模型,并搭建无线充电系统接收端样机,实验测试表明本文设计的电路能够接收发射端传输的电压电流信号,并且保持同步,输出电压稳定。

The traditional wired charging method has many disadvantages,such as mechanical aging,leakage and space.The wireless charging method can solve the above problems,which has good practicability and development prospects.Based on the electromagnetic induction theory,a simulation model of a series-parallel dual-resonant wireless charging system is established to verify its equivalent circuit,and a prototype of the receiving end of the wireless charging system is set up as well.Experimental tests show that the circuit designed in this paper can receive the voltage and current signals which are transmitted by the transmitting end in synchronization,and the output voltage is stable.
