Analytical analyze of power factor improvement for power converter

This paper present a study about a power supply but which can be extrapolate to all power converter. This study about power factor correction can be utilized in learning process. The study is based on mathematical equations for Flyback converter. I made a case study about the comparison between two types of conduction mode for a power supply converter. In this case study I observe a real difference in a positive sense. This case study was realized from two reasons. First is to help the student in learning process to understand the difference between two different types of a converter working. Second is to see a simple method to improve the power factor for power converter. The difference between the two types of conduction mode was demonstrate applying the mathematical results in Matlab graphics and the improvement of power factor true an input filter was realized in Pspice.
