雙相交錯轉換模式PFC控制器與零電流PFC控制器之比較

本文以實際設計的手法，研製出一 300W具邊界電流控制模式（Critical Boundary Current Mode）的雙相交錯轉換PFC控制器(Dual-Phase interleaved PFC controller)，及一300W具零電流工作模式之主動功因校正器。文中先詳細說明其操作原理及方式，再實際設計整組電路，最後量測其輸入電壓電流波型、輸出電壓電流波型、功率因數值、相關電器特性及元件應力之數據與波形，以比較兩個電路的優缺點。比較實驗結果發現在300W以下輸出功率的電路應用，使用具邊界電流控制模式的雙相交錯轉換PFC控制器可以獲得較佳的優勢，在300W以上輸出功率的電路應用中，使用具零電流工作模式之主動功因校正器可以獲得較佳的優勢。

In This thesis, we study and implement a 300W BCM (Boundary Current Mode) dual-phase interleave PFC (Power Factor correction) circuit and a 300W active PFC circuit with ZCS (Zero Current Switching)。 At first, we describe the operation and topology difference between these circuits, then design and implement both of these practical PFC circuits for performance comparison. Finally, the results of comparisons are presented. According to comparisons of switching waveforms, power factors and other relative experiment results, the BCM interleaved PFC and ZCS PFC are suitable for apply on cases under 300W and above 300W, respectively.
