Simulating and analyse the power factor for Flyback Converters

This paper present a study about a power supply, study which can be applied to another supply circuits. This study can be useful also in the learning process. I start the study from modulation of mathematical equations for Flyback Converter. I demonstrate the difference between Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) true the Matlab graphics. I made analytic numerical calculations to determine the dependencies between power factor and voltage transfer ratio. I made also a Pspice simulation to demonstrate the input filter importance in diminution of harmonics from input current.
