本論文主旨在於討論功率因數修正器之設計，研製一具有高功因、高效率、低電流諧波及高功率密度之升壓型功率因數修正器，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，並針對其種類及控制策略進行分析與比較。最後以升壓型轉換器做為主電力電路架構，採用固定切換頻率及平均電流控制模式，以降低輸入電流諧波，並使輸入電流與電壓同相，達到功率因數達到趨近於1之目的。
在實作上以NCP1653及UCC28070做為控制IC，分別研製2 kW無橋式功率因數修正器及雙相交錯式功率因數修正器。實驗結果驗證了所採控制技術之正確性與可行性，同時也提及後續可能的研究方向，以期更為提高功率及效率。

This thesis is focused on the design and implementation of boost power factor correctors (PFC) to achieve a high power factor, low input current harmonics, high efficiency and high power density. In addition, the voltage and current ratings of the power switches, and the volumes of inductors, output capacitors and EMI filters can be reduced. Various types of PFC topologies and several control schemes are also discussed and compared. Finally, the average current mode control with a constant switching frequency is adopted. The main objective is to reduce the input current harmonics and to achieve a unity power factor.
Two 2-kW PFC(bridgeless power factor corrector and two-phase interleaved boost power factor corrector) prototypes are implemented based on the NCP1653 and UCC28070 control IC’s, respectively. Satisfactory experimental results confirm the validity and feasibility of the adopted schemes. Potential future works are mentioned to further improve the power level and conversion efficiency.
