基于前饋混合控制的BOOST型PFC控制器

摘要：:改善功率因數控制器的動態響應仍然是一個熱門話題，本論文提出了一種新型功率因數控制器，能夠達到快速響應的目的。采用升壓式功率因數校正電路的大信號模型，并對實際硬件電路進行分析和研究，以及進行實驗和仿真結果比較。 敘詞：前饋控制、混合控制、L4981A、功率因數 Abstract：How to improve fast response of　PFC　is　still one of the hottest issues　at present. This paper describes an brand-new PFC　which can reach the aim .The controller is based on a linear large-signal of the boost converter. A hardware design is presented and analyzed,　and experimental results are presented and compared with simulations. Keyword：feed forward control 、hybrid control、L4981A、power factor
