Consider 2nd stage LC filter in Flyback converter to significantly reduce output voltage ripple

AEP3629_Fig1

The Flyback topology is a popular topology in off-line charger applications due to its capability to handle wide input voltage range. And multiple outputs are easily generated by using extra windings on the main transformer. Figure.1 illustrates the Flyback converter with multiple outputs.
