摘要

本論文的目的是設計和實現數位化控制的雙開關順向式轉換器的功率因數校正。該控制器包括兩個控制迴路。內迴路控制採用平均電流模式控制，使輸入電流能追隨正弦命令電流進而改善功率因數，外迴路控制則調整輸出直流電壓。
具有功率因數校正之雙開關順向式轉換器已被設計與實現。本文所研製的詳細規格如下：
輸入交流電壓：110 V
輸出直流電壓：48 V
輸出功率為：400 W
切換頻率：100 kHz
實驗結果證明，整體效率達到83.5%，PF=0.99。

The objective of this thesis is to design and implement digital controlled double forward converter with power factor corrector. The controller consists of two control loops. The inner loop is controlled using average current mode control to force the current following its reference to improve the power factor, and the outer loop is for voltage control to control the DC-link voltage.
A double forward converter with power factor corrector has been designed and implemented. The specifications of this converter are as follows:
Input voltage = 110 V/AC
Output voltage = 48 V/DC
Output power = 400 W
Switching frequency = 100 kHz
Experimental results show that the maximum efficiency is 83.5% and power factor is 0.99.
