本論文針對主動式功率因數修正電路進行相關研究，一方面建立起功因修正電路模型，並發展一套有可靠信以及有效率的模擬平台；另一方面以比例積分控制器當作電流迴路、電壓迴路的核心，來達到控制昇壓式轉換器電路的電壓與電流。最後製作功因修正硬體電路，實驗以及驗證功因修正的目標。

This thesis aims to investigate an active power factor correction (PFC) circuit and its mathematical model, in order to develop a reliable and efficient simulation platform. By using the PI controller, we can control the inductor current and the output voltage of the boost converter. Finally, we constructed the circuit and analyzed the results to verify that our mathematical model is valid.
