无线电力传输（WPT）实现了从电源侧线圈（$T_{x}$）到接收器侧线圈（$R_{x}$）的非接触电力传输，其具有广泛的应用。然而，对于水平随机移动的$R_{x}$，由于$T_{x}$和$R_{x}$之间的相对距离影响PTE的值，不能保证高的功率传输效率（PTE）。本文设计了一个四层的$T_{x}$阵列，利用$R_{x}$跟踪算法跟踪$R_{x}$的位置并激活阵列中该位置的$T_{x}$。因此，对于自由运动的$Rx $，可以获得最大且稳定的PTE，这已经在模拟实验中得到了证明。
Wireless power transfer (WPT) enables contactless power transfer from the power supply side coil ($T_{x}$) to the receiver side coil ($R_{x}$), which has a wide range of applications. However, for a horizontally randomly moving $R_{x}$, high power transfer efficiency (PTE) cannot be guaranteed as the relative distance between $T_{x}$ and $R_{x}$ affects the value of PTE. In this paper, we designed a 4-layer $T_{x}$ array with $R_{x}$ tracking algorithm to track the position of $R_{x}$ and activate the $T_{x}$ at that position in the array. Therefore, the maximal and stable PTE could be achieved for a freely moving $R_{x}$, which has been demonstrated in simulation experiments.
