本論文旨就饋電軌道系統，應用非接觸式電能傳輸技術，研製饋電軌道系統之充電區塊，提供電動載具因號誌而停駐時進行電能補給，藉以改善電動載具駕駛於無鋪設饋電軌道區段之續航力問題。為了提高長距離下傳輸效率與水平偏移容忍度，故採三線圈式感應耦合結構，透過附加獨立線圈於饋電側，有效蓄積饋電槽供給之電能以增強磁場發射，並將附加線圈設計為多單元結構使磁場均勻分布。本研究亦探討操作頻率對於三線圈式電能傳輸效率之影響，並試製三種耦合結構配置Type I、Type II與Type III，比較上述結構於兩操作頻率30 kHz與300 kHz下電能傳輸差異。由實驗結果可得Type III結構配置較能避免由於饋電與受電線圈耦合而影響傳輸效率。在傳輸間距為15 cm情況下，當操作頻率為300 kHz時，其最大傳輸效率約70 %。

This thesis is aimed at applying contactless inductive power transmission technique to implement the charging area for contactless power track system. The charging area is applied to achieve the objective that the electric vehicles can be charged when stopping at the traffic light, which improves electric vehicles endurance when driving on the road without the power track. To increase the power transfer ability of charging area with large distance and lateral misalignment, the three-coil inductive coupled structure is adopted. By placing the additional coil in the transmitter, it can enhance the magnetic flux because of the efficiently cumulative energy. The additional coil is designed as a multi-cell structure to distribute the uniform magnetic field. The transmission efficiency of the three-coil power transfer with the different operating frequency is also discussed in this study. The experimental models of the coupled structure Type I, Type II, and Type III are set up, and the power transmission efficiency with the operating frequency 30 kHz and 300 kHz are compared. The experimental results show that the Type III structure can reduce the impact of the coupling between source coil and receiving coil. When the transmission distance is 15 cm and operating frequency at 300 kHz, the transmission efficiency of the system can be up to 70 %.
