The invention provides a non-resonant end inductance compensation circuit and a non-resonant coil extension cord of a wireless charging system, the non-resonant coil extension cord is characterized in that two Litz wires are wound to form a flat and tightly arranged conductor as an internal lead, and a grounding copper net and an insulating layer are coated outside the lead, so that current is effectively increased, and the service life of the non-resonant end inductance compensation circuit and the non-resonant coil extension cord is prolonged. And radiation is reduced. The non-resonant end inductance compensation circuit comprises the non-resonant coil extension line, and two ends of the non-resonant coil extension line are respectively connected with the transmitting end non-resonant coil and the transmitting end control circuit, so that the inductance compensation circuit is utilized to carry out inductance compensation on the transmitting end non-resonant coil to meet the requirement of magnetic type wireless charging; and the problem of unstable charging caused by inductance value change when the non-resonant coil of the wireless charging transmitting end is prolonged and changed is effectively solved.

    本发明提供了一种无线充电系统的非谐振端电感补偿电路及非谐振线圈延长线,其中,所述非谐振线圈延长线是由两个利兹线绕设形成扁平状且紧密排布的导体作为内部导线,并于导线外部披覆接地铜网及绝缘层,以有效提升电流,降低辐射。所述非谐振端电感补偿电路中包括所述非谐振线圈延长线,所述非谐振线圈延长线的两端分别与发射端非谐振线圈和发射端控制电路连接,借此,利用所述电感补偿电路对发射端非谐振线圈进行电感补偿,以满足磁吸式无线充电的需求,有效解决无线充电发射端非谐振线圈延长变化时电感量变化造成的充电不稳定问题。
