本文旨在研製具新型三相感應耦合結構之電動車用感應充電槳，與傳統單相耦合結構者之不同處，在於以三相激勵電源驅動三相感應耦合結構，各相鐵芯柱彼此之間共享磁通路徑，實現以較小鐵芯體積下獲得較高功率密度與感應電能傳輸能力之目的。文中使用等效磁路模型與有限元素模擬軟體Maxwell分析，針對不同外形輪廓之三相鐵芯耦合結構進行磁場模擬與磁路模型建立，進而提出整體鐵芯利用率高，且適於三相感應充電槳系統之新型三相鐵芯耦合結構。次級側使用降壓充電電路搭配單晶片PIC18F4520控制實現對磷酸鋰鐵電池進行定電流-定電壓充電。最後以實驗量測，結構間隙在0.4mm下，最大感應電能傳輸效率為88%，最大接收功率為946W。

The purpose of this thesis is to design and implement an efficiency three-phase contactless inductive charging paddle. Several types of core shape are investigated and their magnetic circuits are simulated and analyzed. Therefore, a new-type three-phase core structure is proposed. In the secondary side the buck-type charging circuit that refer to CC-CV charging algorithm is implemented by PIC18F4520 microcontroller for LiFePO4 battery. Finally, the experimental verification, when gap of inductive coupled structure is 0.4mm, the highest transmission effi¬ciency is 88%, the maximum received power is 946W.
