摘要

本論文探討同步順向電源轉換器的電氣特性，找出較佳的效率方案，並實際製作400瓦之電源供應器，來證明實驗結果與理論相互對應。在順向電源轉換器的電路中，磁性元件的選用，是非常重要的關鍵因素，對於轉換器的特性效率有相當程度的影響，因此如何選擇更適當的元件，適當的工作頻率進而設計同步順向電源轉換器電路，使其小型化以及高效率為本文的目標。

This paper discusses the electrical characteristics of Synchronous forward isolation power converter to find a better efficiency approach, and actually develop a 400W power supply, to prove that correspond with the theoretical results. In the circuit of the forward-type power converter, the use of magnetic components is very important factor which influence the key characteristics of the converter, wishing to improve the efficiency of the converter, it shall to study the magnetic components and choose the more appropriate components, as well as a more appropriate circuit operating frequency and thus achieve the miniaturization and high-efficiency goal.
