Transfer function Derived for PWM Switch Model for Flyback(Part 3 of 3 on Must Do’s to Understand a Flyback Output Filter )

AEP3629_Fig2

Benefits to a 2nd Stage LC output filter for flyback:

  • Lower total capacitance needed to achieve output voltage ripple objective
  • Reduce overall footprint of the output filter compared to 1 stage output filter
  • Lower output voltage ripple more dramatically

Problems introduced by a 2nd Stage[……]
