本文重點研究了具有雙輸出的無線充電應用，並探討克服複雜發電方式。串聯無線功率傳輸（WPT）系統架構用於分析，設計和實現。首先，簡要介紹了WPT的基本原理，並對WPT應用中弱耦合線圈的等效電路模型進行了綜述。利用數學理論分析了兩個接收線圈之間的相互作用耦合對整個系統的影響，計算了發送端的虛阻抗為零的工作頻率點。本文提出了一種能夠保證雙輸出WPT系統在設定的耦合係數變化範圍，負載範圍和允許工作頻率範圍內正常工作的設計方法，可以作為實驗研究的依據最後以實作電路並完成可以使兩組接收器的輸出同時達到30 W的輸出，發送端與接收端垂直距離10 mm，而兩組接收線圈之間的距離則分別三種不同的狀況: 0 mm、20 mm、40 mm，最終在各項測試條件都能夠讓電路擁有最小的虛功率。

This thesis focuses on a wireless charging application with dual outputs and discusses the challenges with complex power generation. The series wireless power transfer (WPT) system architecture is used for analysis, design and implementation. Firstly, a brief introduction of the basic principles of WPT is given and the equivalent circuit models of loosely-coupled coils for WPT application are reviewed. The influence of the interaction coupling between the two two receiver coils on the whole system is analyzed using mathematical theory to calculate the operating frequency point at which the reactive impedance of the transmitter is zero. A design method that can guarantee normal operation of the dual-output WPT system under given coupling coefficient variation range, load range and allowed operating frequency range is proposed in this thesis, and can be used as a basis for experimental research. Finally, the circuit can be implemented and the output of the two sets of receivers can reach 30 W at the same time. The vertical distance between the transmitter coil and receiver coil is 10 mm, and the distance between two receiver coils has three different cases of 0 mm, 20 mm, and 40 mm. Finally, in each test condition, the circuit minimizes the reactiver power.
