| Abstract: | In order to solve the problem that detection coil should be introduced into wireless charging foreign body detection based on impedance characteristics,a dual-frequency induction wireless charging method is proposed in this paper,in which high frequency excitation is used for foreign body detection and low frequency excitation for wireless charging,which avoids the introduction of detection coil and reduces the complexity of the system.In this paper,the characteristics of dualfrequency induction circuit are analyzed,the circuit parameters are designed,and the simulation verification is carried out,and the feasible design scheme is obtained. |
