A Guide to Flyback Transformers | Coilcraft

A flyback transformer is a coupled inductor with a gapped core. During each cycle, when the input voltage is applied to the primary winding, energy is stored in the gap of the core. It is then transferred to the secondary winding to provide energy to the load. Flyback transformers are used to provide voltage transformation and circuit isolation ...

IET Digital Library: Constant-flux inductor with enclosed winding for high-density energy storage

The ''constant-flux'' concept has been described in a recent Letter as a way to utilise space more efficiently for inductor geometry with the core enclosed by winding. While the concept can conceptually be extended to the companion case of the inductor with winding enclosed by the core, structural synthesis is complicated by the absence of circular symmetry.

''Magnetics Design 5

Figure 5-5 shows the characteristic of a core with optimum gap, limited by core saturation and by max. current density in the windings. The area between the characteristic and the vertical axis indicates the en-ergy storage capability. Any other slope (different gap size) results in less energy storage capability.
