Web• Fly-back • Forward • Half bridge • Full bridge • Push Pull About Fly-back converter circuit working operation: The figure depicts flyback converter circuit. Fly back is a buck boost chopper with isolated division to configure a transformer. With the additional advantage of isolation, the voltage ratio is multiplied. WebTheoretically cross-regulation in a flyback converter should be better then that of a forward converter, since an additional magnetic (inductor) is needed for the forward converter. In practice this is not the case. Due to the storing of energy during the on time, Ton, the input current will reach some maximum peak, Ip, at the end of Ton.
