本論文以無線電力傳輸的架構作為充電平台對無人機充電的方式，無線充電因為廣泛的應用與其技術的精進，使得許多充電方式均採用無線充電的架構。本文介紹無線充電的傳輸架構與傳輸特性並比較其優缺點。無人機充電系統以太陽光電能作為系統的供電來源，在有日照的情況下對充電平台的電池組充電並配合最大功率追蹤控制法則擷取太陽光電能最大功率，並供給整個充電平台作電力的無線傳輸。無線電力傳輸以全橋電路架構來實現，經由設計完成之發射與接收線圈來實作驗證。接收端以降壓電路對無人機上的電池組作充電，來達到無線充電的目的。
本論文利用ANSYS模擬軟體，設計與分析無線充電之發射線圈及接收線圈的形狀與尺寸對耦合效果的影響。尤其是無人機降落時可能發生發射線圈與接收線圈無法準確地對準的現象即為錯位，透過模擬的方式來選取對錯位影響最小的線圈外型並實作驗證。此外，本論文採用無線充電共振耦合式的傳輸方式，對於傳輸電路之諧振電路的匹配會加以設計，並對無線充電的實際線圈與諧振電路實作驗證。最後，太陽光電能無線充電的電路架構與控制法則，於實際的無人機上實驗驗證其可行性與正確性。

This thesis focuses on utilizing wireless power transfer (WPT) as a charging platform for the UAV. Wireless charging is a well-established technology that uses various electronic power circuits for charging devices without wires. This thesis presents the transmission architecture and transmission characteristics of wireless charging and compares their respective advantages and disadvantages. The UAV charging system harnesses solar energy as its primary power source. When there is sufficient solar illuminance, the battery packs are charged using solar panels. The electric power circuits are precisely controlled to operate at the maximum power point for efficient solar power transfer to fulfill the power requirements of the entire charging platform. The wireless power transmission is implemented using a full-bridge topology, which is verified by designing transmitting and receiving coils. The receiving coils integrate a buck circuit to charge the battery pack of the UAV.

In this thesis, the ANSYS simulation software was utilized to design and analyze the influence of the shape and size of the wireless charging transmitting coil and receiving coil on the coupling effect, especially when the UAV lands on the charging platform, where misalignment may occur between the transmitting coil and the receiving coil. Based on the simulated results, the coil with the least impact on misalignment is selected and verified. Additionally, this thesis adopts the wireless charging resonant coupling transmission method, and the resonant circuit of the transmission circuit is designed and simulated to prove the effectiveness of the actual coil and resonant circuit of wireless charging. Finally, the resonant topology and maximum power point tracking (MPPT) control of the solar power wireless charging system are tested on an actual drone to verify the feasibility and correctness of the proposed method.
