摘要

本論文主要目的在研製具有均流控制之數位交錯式功率因數修正器，以達到減少電流漣波，並改善元件體積以及耐流，且可讓輸入電壓與輸入電流同相位以提升功率因數和調整輸出電壓。
本文新型均流控制是參考於龍門式架構，將兩軸位置誤差比擬為兩組昇壓型功率因數修正器電感電流誤差，並將兩組昇壓型功率因數修正器電感電流誤差互相補償以達到均流之功能，並與其他三種均流控制比較。
三種均流法則分別為功率分配均流法、主僕式均流法1及主僕式均流法2，根據實驗結果的驗證，均流效果較好的為功率分配均流法及龍門控制均流法，但功率分配均流法需在兩組電感值趨近相等的情況下，才能擁有最佳的均流效果，而龍門控制不需要平衡基準點，故在電感值有所誤差時也能擁有好的均流效果。

The objective of this thesis is to design and implementation of digital-controlled power factor corrector. Therefore, the current ripple can be reduced and thereby improving the volume and current rating of power devices. Moreover, the input current can track its input voltage to increase power factor while regulating the output voltage.
A new current sharing control similar to Gantry Stage theory is proposed. The two-axis position errors correspond to inductor current error of boost converter. To achieve current balance, two boost converter inductor currents are used to compensate current deviation. Apart from Gantry Stage, three traditional current sharing methods are used to verify Gantry Stage method.
Three current balancing methods are Power Distribution, Master-Slave I and Master Slave II. Based on the experimental results, the Power Distribution and “Gantry Stage” are better than the others. However the Power Distribution has better current sharing when two inductors values are equal. The Gantry Stage does not need to balance point, so it is able to provide good current sharing even with the inductor value tolerance.
