传统的单激励线圈系统有传输距离和传输角度的限制。为了解决这一问题，提出了四线圈激励的无线电能传输系统。通过将4个激励线圈分别放在平行和垂直位置的方式，不仅可以延长能量传输距离，而且减弱了传输方向的敏感度。为简化分析，将激励线圈等效为磁极，根据 N/S 极性，提出了区域线圈的4种绕组连接方式，通过理论分析和仿真，对其区域磁场分布进行研究。给出了区域等效电路模型，对比单激励线圈系统，推导出参数设计方法，给出了补偿电容的计算依据。以获取最大磁场强度为目标，选取 S-S-N-N 绕组连接方式，构建了一个0.8 m×0.8 m×0.8 m 的四线圈激励的共振式无线能量传输区域，验证了参数设计的正确性，并说明了采用四线圈构建供电区域可延长传输距离，减弱传输方向的敏感度。

Wireless power transmission region stands out for its convenience in applications where several terminals or movable terminals need to be charged.The conventional single coil excited charging region has the drawback of distance and angle limitation.To overcome the shortcoming,a charging region constructed by four excited coils is proposed.This four exciting coils configuration can not only increase the transmission distance,but also weaken the sensitivity to angle change.By regarding the excited coil as a magnetic pole,four winding connection types of the four excited coils are put forward.By both theoretical analysis and software simulation,magnetic field distributions of these four winding connection types are studied and S-S-N-N is finally selected as the winding connection type.The equivalent circuit for this configuration is derived and the parameter design method is further presented.Finally,a 0.8 m×0.8 m×0.8 m wireless power transmission region with four exciting coils via magnetic resonances is fabricated in the lab and the experimental results can verify the correctness of parameter design and the effectiveness of the proposed four coil excited charging region.
