摘要

本篇論文研製一交錯式升壓型功率因數修正器，功率級電路為兩組升壓型轉換器電路架構，採用德州儀器公司所生產的控制IC UCC28019DRG4，控制輸入電源電流操作於連續導通模式，並且使用單穩態多諧觸發IC HEF4528BP所組成之相移控制電路，實現輸入電流之交錯式控制。交錯式控制方式可將輸入電流分流至兩個並聯的功率因數修正電路，藉以降低每個開關的電流應力以及減少開關操作時的損失，亦可解決儲能電感體積過大等問題，且具有低輸入與輸出電流漣波的優點。 最後實際研製一台400W交錯式升壓型功率因數修正器驗證本論文之設計與分析，實際電路之測量結果顯示在輸入電壓為110±20V(85V至130V)且輸出電壓390V的規格下，滿載時之功率因數可達0.994以上，且效率可達95%以上。

This thesis implements an interleaved boost power factor corrector (PFC) using IC UCC28019DRG4 as the control core to operate the PFC in continuous current conduction mode (CCM) and the associated mono-stable multi-vibrator HEF4528BP to perform the required interleaved control. The power stage consists of two boost PFCs in which inductor currents are interleaved to share the source current and reduce the current stress and loss on each switch. In addition, the inductor size and the ripples on input and output can be reduced.
A 400-W two-phase interleaved boost PFC is implemented to verify the analysis and design. The experimental specifications of the implemented interleaved boost PFC includes input voltage 110?20?V?85V to 130V?, output voltage 390V and output power 400W. The experimental results show that the power factor reaches 0.994 under full load condition and the efficiency is up to 95.
