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. The forward converter is therefore somewhat more complex in design, but also achieves a higher efficiency. Push …
