指導教授 : 賴炎生

摘要


本文主旨在設計和製作一個具有功率因數校正的單級返馳式轉換器,輸入交流110伏特,輸出直流12 伏特。首先分析單級返馳式轉換器電路的基本原理,其次說明轉換器的設計和實驗結果。 本文以 NCP 1651 G積體電路實現具有功率因數校正之單級返馳式轉換器的控制器。實驗結果顯示所研製的轉換器,其功率因數高於0.85,而且效率高於80%,藉此驗證設計與實作的正確性。

The objective of this paper is to design and implement a single-stage fly-back converter with power factor correction. The input voltage is 110 V/AC and output voltage is 12 V/DC. The basic principle of the single-stage fly-back converter is analyzed, and then the design and implementation of this converter are presented. For the implementation, the control IC of NCP1651 G is used as controller. Experimental results show that the power factor is higher than 0.85 and the efficiency is greater than 80%. These results fully confirm the design and implementation.
