本論文旨在研究非接觸式感應電能傳輸技術，並將其應用於油電混合車之充電系統中，利用多鐵芯的耦合結構組成充電槳及充電槽，藉以增加鐵芯的利用率，適合應用於潮溼或是特殊的環境進行充電。文中首先對不同形狀的鐵芯結構進行模擬與分析，並選用適合的鐵芯組成多鐵芯的耦合結構，非接觸式感應耦合結構為RM型鐵芯所構成。透過初級側及次級側的諧振電路增加系統整體效能，並在初級側使用諧振點追蹤的電路，使初級側在負載的變化下，仍操作在諧振點上。系統的輸入電壓為AC110V，使用12V/7Ah的鉛蓄電池進行充電，在氣隙1mm下最高效率為74%。

This thesis investigates the inductive charging technique for charging paddle of Hybrid Electric Vehicles. Charging paddle and charging receptacle are formed by multi-core coupled structure, so as to improve the core’s utility. It is adapt to charge in humid or particular environment. At first the coupled structure is designed by analyzing the comparison of different cores. Second, the coupled structure is established by constituting the adequate multi-core. The Inductive coupled structure is formed RM core. The system is raised efficiency by adding the compensative circuit, and utilizes the resonant frequency tracing circuit to maintain primary side resonant frequency for the change of load. Finally this system with input AC(110V) is implemented in real circuit charging the 12V/7Ah lead-acid cell, and the power transmission efficiency of contactless inductive structure is 74% under 1mm gap.
