You could have Trr trouble in the rectifier - a Schottky barrier type is faster, as long as you keep within its low reverse voltage rating.Hi
i have a problem
i build ac dc converter based on flyback and i get in outpout sawtooth with rippel 1v
i should get stable voltage in outpout
input: 110-230Vac,outpot 12v 1A
i used chip viper37LD and isolated feedback

Forward conduction in a flyback converter would be obvious by the low output.Are you sure you have the phasing right on that transformer? Could it be that you are rectifying the forward part of the pulse, and not the flyback?
