摘要
本文研究了无桥Boost PFC电路,由于省略了整流桥,效率比传统的Boost PFC高,但由于其电感的特殊位置,给电感电流号的检测带来了困难。本文提出了一种基于精密整流电路的新型电流检测方法。研制了一台300W的原理样机,并通过实验验证理论分析的正确性。
This paper focuses on Dual Boost PFC（DBPFC） it shows higher efficiency compared with traditional Boost PFC, but it is not verst easy for current sensing because of the inductor＇s location.A new current sensing is proposed in thi paper to solve this problem. Finally a 300W prototype is designed. Experimental resulis verify ihe correctness of the theoretical analysis.
