本論文旨以非接觸式感應電能傳輸技術設計一個供電墊，俾提供電子紙、PDA、智慧型行動電話與MP4等小功率可攜式多媒體電子產品之桌面上供電。文中首先論述非接觸式電能傳輸之原理與應用範疇，接著提出系統所使用之電路架構與感應耦合結構，並探討漏感成份對感應傳輸之影響，繼而導入諧振電路設計，改善電路阻抗特性，增加系統性能。為有效地使用供電墊，結合單晶片控制電路實現選擇觸發功能與頻率切換控制，針對負載的位置開啟初級側線圈與調整系統操作頻率，使兩者得到較好的配置。最後藉由實測驗證非接觸式感應耦合結構，於30mm氣隙下之最高電能轉換效率達72%。

This thesis presents the design of contactless power supply pad for low power portable multimedia electric appliances, such as electronic papers, PDA, smart phone or MP4. First, the fundamental principle and application fields of contactless power transmission are discussed, and the circuit topology and the coupling structure which this system adopts are proposed. Since the contactless power transmit ability is restricted by leakage inductance, thus the design of the resonant circuit can improve the characteristic of impedance and the system performance. In order to employ pad effectively, microcontroller is utilized to implement selective excitation circuit and switching frequency circuit. Experimental results show that the power transmission efficiency of contactless inductive structure is 72% under 30mm gap.
