摘要

本篇論文主要目的是利用變壓器線圈感應耦合的原理設計一個無線電力傳輸的感應式充電器。以感應充電技術對電池充電是一個安全且可靠的方法。在感應式充電器裏，其能量的傳輸是經由電磁感應而不是金屬對金屬的接觸。變壓器的一次側鐵心是在充電器端，而變壓器的二次側鐵心則是在電池端。
本論文首先研究如何選擇轉換電路及設計輸入與輸出元件，利用TL494 PWM IC控制輸出電壓，來構成一完整的感應充電器。接著利用所設計出來的感應式充電器，對不同形式的變壓器鐵心，探討其耦合效率。接著研究變壓器一次側鐵心及二次側鐵心之間距的改變對感應充電器的影響。最後對所設計的感應式充電器作分析並討論。

Abstract

The main purpose of this thesis is to study a wireless power transmission of inductive charger utilizing inductive coupling theorem. Inductive charging technology offers a safe and reliable method for battery charging. With inductive charging, the energy is transferred via magnetic induction rather than ohmic contact. In such a system, one core is in charging side and the other is in battery side.
This thesis first studies how to select converter circuits and how to design input and output components, and then, coupling efficiencies for different transformer core configurations and the effects of gaps between the primary core and the secondary core are studied. Finally, the inductive charger is analyzed and discussed.
