WebMar 11, 2015 · Think of the flyback as coupled inductors. It must store energy. The inductance must be finite. The forward converter uses a transformer proper -- in the … 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. 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. earth 1984
