碩士 === 國立成功大學 === 電機工程學系碩博士班 === 97 === This thesis investigates the contactless power transmission system for contactless charging paddle of hybrid electric vehicle with multi-core inductive structure. The Charging paddle can be applied in humid or particular environments. At the beginning, the multi-core inductive structures are simulated and analyzed. Select adequate multi-core inductive structures to make a 5.8 centimeters square charging paddle and charging receptacle, and adopt resonant circuit to improve power transfer ability. In order to accelerate charging speed, use Reflex charging algorithm which integrates microchip control circuit for a faster charging process on lead acid battery. The primary and secondary inductive structures are constructed by the multi-core inductive structure; both structures adopt position matching method and the air gap 1mm specification to design the system circuit parameter. This hybrid electric vehicle’s charging paddle system has proven to be practicable by experiments. The transmission efficiency can reach a maximum of 74 % when charging a 7Ah lead acid battery.
