how sepic converter acts as power factor correction stage

[manohar.k]

i am looking for power factor correction through sepic converter? and it should be integrated with half bridge inverter. what amount of ripples that appears at the output stage?

 

[Anna Conda]

Well the ripples depend on the amount of POWER you want at the output and the size of the caps on the output, and their quality, you might want to tell us some basic details when you make a post, else it is very hard to make sensible answers and suggestions....

sepic pfc is ust like flyback pfc...remember in a coupled sepic, the fet and diode currents are just the same as in a flyback of the same turns ratio (1:1).....if its uncoupled sepic, then the fet and diode currents are the same as long as you consider a flyback with half the inductance as the uncoupled sepic.
