The invention provides an electric vehicle wireless charging system with power level interoperability, which comprises two charging channels, the channel 1 adopts a monopole coil, the channel 2 adopts a bipolar coil, and the coils of the two charging channels form a cross-arranged coupling structure; the transmitting end adopts an inverter formed by four switching tubes; two ends of the channel 1 are respectively connected between a switch tube S1 and a switch tube S2 of the inverter and between a switch tube S3 and a switch tube S4; two ends of the channel 2 are respectively connected between the switch tube S1 and the switch tube S2 of the inverter and the negative electrode of the power supply; the receiving end adopts three groups of half-bridge uncontrolled rectifiers which are connected in parallel; two ends of the channel 1 are respectively connected between the first half bridge and the second half bridge; and two ends of the channel 2 are respectively connected between the second half bridge and the third half bridge. By changing the conducting states of the four switching tubes of the transmitting end, four different levels of output power can be realized on the premise of not changing the input voltage.

    本发明提出一种具备功率等级互操作性的电动汽车无线充电系统,包括两个充电通道,通道1采用单极型线圈,通道2采用双极型线圈,两个充电通道的线圈构成交叉排布的耦合结构;发射端采用4个开关管构成的逆变器;通道1的两端分别接入逆变器的开关管S1和开关管S2之间,以及开关管S3和开关管S4之间;通道2的两端分别接入逆变器的开关管S1和开关管S2之间,以及电源负极;接收端采用3组相并联的半桥不控整流器;通道1的两端分别接入第一半桥和第二半桥之间;通道2的两端分别接入第二半桥和第三半桥之间。通过改变发射端4个开关管的导通状态,可以在不改变输入电压的前提下,实现四种不同等级的输出功率。
