摘要

本論文旨在針對可攜式電子產品，提出了應用非接觸式感應充電電路。有別於一般直接金屬連接之傳統充電方式，非接觸式感應充電技術乃是利用無線電波原理，間接地對充電電池達成無接點感應充電。本論文以charge-pump電路去充電一個手機的鋰電池。這個設計根據一個非常簡單的概念，利用天線接收RF能量，輸出它到charge-pump電路並且使用這能量供給電路能量。這研究目的是從現有的charge-pump電路中分析、討論適合的charge-pump 電路與及電路的階數。最後的研究成果，是完成第一階段電路板的製作並點亮LED燈。

This paper aimed at designing wireless charger, based upon non-contact inductive charging technology, for portable electronic products. The way for powering portable electronic products is different from traditional direct metal connection charging method. The basic design was to adopt the existing antenna and charge-pump circuit technologies that harvest electromagnetic energy and transfer to the charge-pump circuit for voltage enhancement. Final results show the circuit simulation and realization of PCB that was proved workable by turning on the LED.
