碩士 === 國立成功大學 === 電機工程學系碩博士班 === 101 === This thesis is aimed at designing the three-phase high efficiency contactless inductive charging platform for electric vehicles based on inductive power transmission techniques which is suitable for SAE J-2954. The cellular inductive platform which comprised of three-phase coils with ferrite backing is proposed for improving the uniform magnetic field distribution over the charging surface, effectiveness for stabilizing the amount of the transmitted power against the fluctuating load and have good tolerance to misalignment that help transfer power efficiently. 3-D finite-element analysis modeling is used to optimize the different inductive coupled structure, with the simulated results and verified by the experiments, the three-phase cellular inductive charging platform was proposed. A final three-phase cellular inductive charging platform system was constructed, according to the experimental result, the transmission efficiency can reach to 87.3%.
