摘 要 本篇論文主要在討論高效能直流轉換器之實現。在設計的過程當中,如果架構選擇不當,將會使得輸出效能降低。所以,唯有經過計算與分析設計,才可以提高輸出效率。文中首先將探討半橋式轉換器搭配中央抽頭式以及倍流式架構的基本動作原理,進而說明元件與電路設計上的考量。接著製作出輸出功率一百三十瓦的半橋式-倍流式架構之直流轉換器,進行四種不同架構的實驗,並比較結果,證明了本設計之可行性。
ABSTRACT The aim of this research is to develop a high efficiency DCDC converter. In the process of designing a DCDC converter,the output efficiency will be enhanced if a suitable circuit structure can be chosen first. In this thesis,the basic operation principle of Half Bridge Centro Tap and Current Double structure is discussed. Next, the consideration of component and circuit design is explained. Finally, a practical Half Bridge Current Double Converter based on the theory of DCDC converter is implemented to prove its accessibility. The study is conducted with four different structures.
