本文製作一返馳式轉換器之鋰電池充電系統，有別於傳統充電控制使用兩組類比轉數位通道回授控制以達到定電流、定電壓控制，本研究僅使用一組初次側調整式回授即可達成定電壓、定電流之充電規則。整體論文架構分為三部分：第一部分為返馳式轉換器，此轉換器操作於交流-直流且不連續導通模式下，利用此轉換器並加入初次側調整技術，經由輔助繞組回授輸出電壓，可以去除傳統式使用光耦合器回授之溫度限制以及降低成本。第二部分為實作一5W初次側返馳式鋰電池充電器，其交流輸入電壓範圍85V至265V，滿載效率最高可達78.77%，系統整體效能均符合新式能源之星法規標準；並與現有文獻比較結果顯示，使用本文電路架構在高壓及低壓時，效率分別可以高出4.3% 及3%。第三部分為結合實作與理論分析並提供步驟性的電路設計流程，且提供各項效率改善方案與分析，以利讀者瞭解並設計本文電路架構，縮短系統設計時間。

In this thesis, the lithium battery charging system of a flyback converter was produced. It is different from the traditional charge control by using two groups of feedback control of analog to digital channel to achieve constant current and constant voltage control. In this thesis, using only a group of feedback of primary side adjustment type can achieve constant voltage and constant current charging rules. The overall thesis architecture is divided into three parts. The first part is the flyback converter. This converter operates in AC-DC mode and discontinuous conduction mode. This converter is used and primary side adjustment techniques are incorporated. The output voltage can be feedback through the auxiliary windings. It can eliminate the temperature limit of the traditional optocoupler feedback and reduce cost. The second part is to implement a 5W primary side of the flyback lithium battery charger. The AC input voltage range is from 85V to 265V and full load efficiency is up to 78.77%. The overall system performance is in line with the new Energy Star regulations. The results show that the efficiency can be increased by 4.3% and 3% at high voltage and low voltage, respectively, compared with the existing literature. The third part is a combination of practical and theoretical analysis and provides step-by-step circuit design process and the efficiency improvement program and analysis. Readers can quickly understand and design this circuit architecture and shorten the system design time.
