摘要

本論文主要目的係研製一具有高功因、低諧波、高效率及高功率密度之雙相交錯式連續導通模式定電流輸出功率因數修正器研製。雙相交錯式控制策略不只保有傳統單相脈波寬度調變升壓型轉換器的優點，且在高輸出功率下更可改善功率元件高耐流、儲能電感體積過大、輸出電容過大及EMI濾波器體積等問題。 　　本論文經多次實驗研究，實際製作一800W定電流輸出之交錯式功率因數修正器，以驗證論文中所提之分析與設計考量是否合理。控制電路使用德州儀器公司所生產的IC UCC28070，功率級則採用雙組升壓型轉換器電路架構。經測量結果證明，雙相交錯式架構確實可以減少電流漣波，適用於大功率應用場合。

This thesis focuses on the design and implementation of a two-phase interleaved boost power factor corrector (PFC) under continuous conduction mode (CCM) to achieve a high power factor, low input current harmonics, high efficiency and high power density. A two-phase interleaved boost PFC features the advantages of a conventional single-phase PWM boost converter. In addition, the voltage and current ratings of the power switches, and the volumes of the inductors, output capacitors and EMI filters can be improved.
　　An 800W two-phase interleaved boost PFC is implemented. Experiments are conducted and satisfactory results are measured to confirm the effectiveness and the feasibility of the theoretical analysis and design. The TI UCC28070 is used as the control IC for the PFC. The power stage consists of two boost PFC converters. It is verified that the current ripples are greatly reduced with the two-phase interleaved topology. Thus the two-phase interleaved PFC are especially suitable for serving as a pre-regulator in the high-power applications.
