| Summary: | 碩士 === 國立成功大學 === 電機工程學系碩博士班 === 96 === This thesis studies and analyzes the coupled structure of contactless inductive power transmission to achieve better efficiency for high power vehicle charging. At first, the operational characteristics of inductive power transmission are studied. Second, the design of coupling structure is established by analyzing the comparison of different adequate core. In order to charge high power vehicle, choosing lead-acid battery of high content to investigate the fundamental characteristics. After studying the charging method of lead-acid battery, the thesis chooses one of charging method then analyzes the charging characteristics. The design of system’s parameters is under 2mm air gap of contactless inductive coupled structure, and utilizes the resonant frequency tracing circuit to maintain the conversion efficiency for the change of load and core displacement. Finally, this system is implemented in real circuit to be used to charge lead-acid battery.
