| Summary: | 碩士 === 國立成功大學 === 電機工程學系碩博士班 === 101 === 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.
