Design of Wireless Charging Receiving Circuit Based on Electromagnetic Induction Theory

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.
