本文研製一套感應式功率傳送系統，由全橋串聯諧振轉換器作為前級，利用串聯諧振達到零電壓切換，減少切換損失，並補償線圈產生的虛功以提升輸出功率。後級採用降壓式轉換器，調整功率開關的責任週期改變輸出電壓，達到穩壓的目的。
文中使用圓盤形的感應線圈，利用磁路模擬軟體，探討磁芯擺放的數量與位置，以期在經濟效益下提升能量傳送效率。為了改善功率傳送的能力，文中探討漏感產生虛功的補償方法。
本文使用德州儀器公司TMS320F2808數位信號處理器做為控制核心，並採用混合式普斯卡特(hybrid posicast)控制法則，改善後級輸出電壓的動態響應。最後，實際研製一套輸入電壓為直流220V，輸出電壓為直流144V，輸出功率為1.8 仟瓦的感應式功率轉換器，驗證本文所提方法的正確性及可行性。實測結果說明，本文所研製的系統在一、二次側線圈距離為11 公分時，滿載轉換效率約可達到 87%。相關的結果，未來可適當改良後應用於電動機車的感應式充電。

This thesis investigates the implementation of an inductive power transfer system. A full-bridge resonant converter is used as the front stage. By using a series resonant circuit, the zero voltage switching can be achieved to reduce the switching loss and also compensate the reactive power of the leakage inductance that can increase the output power. A buck converter is used as the back stage to adjust the duty cycle of power devices and then obtain output voltage regulation.
A circular pad is used to install the inductive coils. By using a magnetic analysis simulation software, the number and position of the magnetic cores can be determined to improve the power transfer efficiency within a limited cost. To improve the capability of power transfer, the compensation of reactive power is discussed.
A digital signal processor, TMS320F2808 is used as the control center to execute the hybrid Posicast control algorithm and improve the output voltage dynamic responses. Finally, an inductive power transfer system, which has input DC 220V, output DC 144V, rated 1.8kW has been implemented to evaluate the correctness and feasibility. Experimental results show that the full-load transfer efficiency can reach 87% when the distance between the primary coil and secondary coil is 11 cm. Experimental results show that the proposed method can be used for electric motorcycle charging system after suitable modification.
