| Abstract: | The definition of power factor, the problems of conventional switching power supply and the methods,characteristics are discussed in this article. A novel main circuit topology about APFC and circuits design are given. Moreover its operation process and the methods of power factor correction principle are discussed and analyzed in detail. The results of experiment and PSPICE simulation are showed as well. In the end, it presents the use of APFC IC in foreign. |
