本論文旨在研究非接觸式感應電能傳輸技術，並將其應用於小家電裝置之感應充電系統。文中首先探討非接觸式感應電能傳輸技術之基本原理及其應用範疇，進而論述影響系統操作之相關因素。就感應充電系統之耦合結構設計，係經由比較分析抉擇適當鐵芯結構，且針對所需補償電路進行分析及設計，再導入反射阻抗概念探討充電時負載電流變化對感應耦合之影響。非接觸式感應充電電路則採用雙閉迴路結構，俾維持感應耦合效率兼作過電流保護，並以2.5mm之氣隙規格進行系統電路參數設計。而後將所設計之感應充電系統予以電路實現，再用600mAh鋰電池作為充電負載，測試其於充電過程中隨充電電流變化時之耦合效率表現。經由實測驗證，本文所提非接觸式感應充電系統確具可行性，其於充電過程中之最高耦合效率可達82.1%。

This thesis investigates the contactless power transmission system with a small gap for small household electrical appliances’ inductive charging system. At first the applications and fundamental principles of contactless power transmission systems are studied, then the thesis followed by the discussion of the factors associated with the operating of system. The design of coupling structure is established by analyzing the comparison of different adequate cores. Then, the thesis focuses on the principle and design method of the compensation circuit to explain the practical design. The concept of reflected impedance is also introduced to understand the influence of the secondary load in the whole system. As for the circuit structure, it uses double closed-loop control to keep the coupling efficiency and provide overcurrent protection. Finally, this system is implemented in real circuit to be used to charge a 600mAh li-ion battery. The best coupling efficiency is 82.1% in charging processes with 2.5mm gap.
