本論文設計之控制器應用於升壓型功率因數修正器。設計目標為在保持穩定且準確的輸出電壓，並且降低輸入電流失真，同時校正功率因數近似為1。且特別強調於在負載電流突然變化的情況之下，仍然具有快速的動態響應，第一種為改進調節區逼近(Regulation Band Approach)的方法，結合了一個帶斥濾波器以及一個無作用控制區，使得控制器能夠對於無法避免的輸出電壓漣波的靈敏度降低，同時對輸出電壓的變化仍然保有很大的補償能力;另一種為基於估測的控制方法，使用負載電流估測器用來觀測負載的變化，並利用即時的訊息對當前的命令做修正。而為了驗證控制器，使用DSPTMS320F28069做控制器實現，並應用於1.4 kW的升壓型功因修正轉換器。

The controller design for a PFC boost converter is presented in this thesis. The design objective is to maintain a prescribed constant output voltage and reduce the input current distortion while correcting the power factor toward 1, with particular emphasis on the fast dynamic response under sudden change in load current. Two methods are utilized to achieve this end. One is the improved regulation band method, which combines a filter with a deadzone to make a controller insensitive to the inevitable output voltage ripple while still preserving a good capability of compensating for large output voltage variations. The other is an observer-based method, which makes use of a load current observer to detect the load change and offer instant information for the correction of the current command. For verification, the two methods are implemented on a DSP TMS320F28069 for controlling a 1.4 kW PFC boost converter.
