碩士 === 中華大學 === 電機工程學系碩士班 === 103 === This paper study of wireless power transfer system , and this system apply to charge universal portable product. As used herein, the push-pull converter for the wireless power transfer system and choose EE-type ferrite core for the inductive coupling structure. In the secondary side with a parallel resonant capacitance, improve wireless power transfer system efficiency, input power and output power. The paper will analyze the wireless power transfer system equivalent circuit and EE-type ferrite core reluctance circuit. According to the wireless power transfer system equivalent circuit can derive the system transfer equation. We can design the resonant frequency based on our resonance formula. Finally, the simulation and experimental are proposed to validate the wireless power transfer equation.
