The invention provides a variable integrated inductor energy receiving coil and a wireless charging automobile, a variable integrated inductor is arranged on the energy receiving coil, and the variable integrated inductor comprises an alternating current inductance coil used for a secondary side compensation network and two direct current control windings used for changing the equivalent self-inductance of the alternating current inductance coil. And the two direct current control windings are respectively arranged on the inner side and the outer side of the alternating current inductance coil according to opposite winding directions. The energy receiving coil has the advantages that the variable inductor is integrated on the energy receiving coil, the inductance parameters and the mutual inductance effect of the integrated inductor can be changed according to different requirements, and therefore in the dynamic wireless charging system of the electric vehicle, the transverse anti-offset performance can be further improved on the basis that power fluctuation suppression during guide rail switching is achieved; and compensation of system output power drop during lateral offset is realized by using relatively small direct current.

    本发明提供一种可变集成电感能量接收线圈及无线充电汽车,在能量接收线圈上设置有可变集成电感,所述可变集成电感包括用于副边补偿网络的交流电感线圈和用于改变所述交流电感线圈等效自感的两个直流控制绕组,所述两个直流控制绕组按照相反的绕向分别设置在所述交流电感线圈的内外两侧。其效果是:在能量接收线圈上集成可变电感,根据不同的需求可以改变集成电感的电感参数和互感效果,从而在电动汽车动态无线充电系统中,可以在实现导轨切换时功率波动抑制的基础上进一步提高横向抗偏移性,使用较小的直流电流实现了横向偏移时系统输出功率跌落的补偿。
