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. 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. chronic muscle tightness in shoulders
