本論文針對現階段智慧型移動裝置進行無線充電時，須放置於充電板上易造成使用者的不便，故研製動態定向無線電能傳輸系統，於空間中環形區域內對智慧型移動裝置進行充電，過程中使用者可將其自由移動，因系統是在個人空間中以一對一形式進行電能傳輸，須有特定方向之磁場分佈，且能即時追蹤智慧型移動裝置之位置而自動調整。理論推導出雙正交線圈架構，再以不同電流組合產生不同方向之磁場分佈，接收線圈是參考市售一款符合Qi協定的接收線圈以繞製完成。當系統電路規格相同時，於雙正交線圈外部加入共振槽，能有效提升耦合結構之磁交鏈，雙正交線圈、共振槽及接收線圈組成三線圈架構。整合單晶片、感測模組及無線通訊模組，使系統能追蹤接收線圈位置。若將空間中環形區域劃分12等份，以Y軸為0°開始每增加30°為一等份，實驗結果為環形區域內磁場分佈之精準度，在不同電流組合可明確指向此12等份。

This thesis is aimed to resolve the inconvenient smartphone is put on the charging board when using wireless power transfer at this stage. The study on dynamic orientation wireless power transfer is designed to charge smartphone using freedom in the annular space. Because the system transfer power one-on-one with smartphone in personal space, magnetic field concentrated in specific direction can immediately track smartphone position to adjust automatically. Orthogonal coil is theoretically analyzed. Using different current combinations to generate magnetic field distribution in different directions. The receiving coil is completed by referring to commercial receiving coil conforms to the Qi standard. When the system circuit specifications are identical, adding resonance tank on orthogonal coil’s exterior. Magnetic flux generated by the system can be effectively improved. Three-Coil is composed of orthogonal coil, resonance tank, and receiving coil. The system can track receiving coil position by integrating single-chip, sensor module and wireless communication module. If the annular space in the space is divided into 12 equal parts. Y axis is used as 0°, each increase of 30° is one equal part. The experimental results show that the accuracy of the magnetic field distribution in the annular space be clearly pointed to these 12 equal parts under different current combinations.
