1. With promulgation and obliging actualization of iec 1000 - 3 - 2 etc . international standards , power factor correction ( pfc ) technique become a hotspot of research in power electronics field . based on average current mode , the paper introduce the design and implementation of a fully digital controlled single - phase boost power factor corrector with fast response . the control - loop circuit is realized using digital control and the corrector can tend to unity power factor , lower current harmonics and high transfer efficiency
   本文在平均電流模式控制的有源功率因數校正技術的基礎上，設計了一種控制電路基于數字信號處理器( dsp ) 、主電路采用boost變換器拓撲結構的全數字單相功率因數校正器，用數字電路代替傳統的模擬電路來實現對整個回路的控制，最終使得校正器具有輸入功率因數接近于1 、低電流諧波以及高轉換效率的特性。
2. It's difficult to find control-loop in a sentence. 用control-loop造句挺難的
