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. WebMay 13, 2024 · The difference between flyback vs. forward converters lies in the inductive energy storage. In the flyback converter, the energy storage is the transformer itself, which is why a transformer with an air gap is needed. The forward converter uses a transformer without an air gap, so an additional storage choke is needed. sight impaired aids
