摘要

本論文是以升壓轉換器拓撲結構為基礎，設計和實現1千瓦的功率因數修正器（簡稱PFC）。這項研究除了整流功能外，其目的在於探討電力品質和諧波失真。 本研究之PFC變換器操作在連續導通模式（CCM），是以平方律誤差估計作為控制參考值，進行平均電流控制模式以穩定輸出電流。在實現中，本研究採用IC UC3854執行PFC轉換器的控制，並由電壓和電流特性的測量結果進行PFC轉換能力和性能的驗證。

This thesis, based on the boost converter topology, is to design and implement a 1-kW power factor corrector (PFC). Except the rectified function, the power quality and harmonic distortion are stiudied in continuous-conduction mode (CCM). In addition, the square-law error estimate is used as the control reference, which achieves average current control for stabilizing the output current. In implementation, IC UC3854 is used to perform the PFC converter. Experimatal results show that the PFC performance almost meets the estmations.
