上一筆

功率因數修正器已廣泛討論且應用在電源供應器。功率因數修正器目的是為了改善輸入電流波形並降低虛功率。在低功率應用上，升壓型功率因數修正器一般採取操作在非連續導通模式或者邊界導通模式。功率因數修正器操作在邊界導通模式的優點為可降低二極體逆向恢復損失之功耗以及簡易的控制策略。在此篇論文裡，一項無偵測輸入電壓且操作在邊界導通模式的數位控制升壓型功因修正轉換器被提出，此項控制技術是利用數位比例積分控制器來決定導通時間，而數位信號處理器中的比較器則係偵測電感電流零點來導通功率開關。最後實現200 W升壓型功因修正轉換器，以驗證所提出控制方法之可行性。

The use of power factor correction (PFC) converters is widely discussed and considered for most off-line power supplies. The aim of the power factor correction (PFC) converter is to shape the input current to minimize the reactive power. For low power applications, boost PFC converter operated in discontinuous conduction mode (DCM) or boundary conduction mode (BCM) is usually employed. The advantages of PFC operating with BCM are the reduction of reversal recovery loss of diode and the simple control. In this thesis, a digital-controlled method for boost PFC operating under BCM without input voltage sensing is proposed. For this proposed control method, the digital voltage PI controller is used for determined the constant on-time period and the comparator block inside the DSP is used to detect the zero-crossing of inductor current for turning on the main switch. A 200W boost PFC prototype is implemented and tested to verify the feasibility of the proposed control scheme.
