Energy Stored in an Inductor
In a pure inductor, the energy is stored without loss, and is returned to the rest of the circuit when the current through the inductor is ramped down, and its associated magnetic field collapses. Consider a simple solenoid. Equations ( 244 ), ( 246 ), and ( 249) can be combined to give. This represents the energy stored in the magnetic field ...

Flyback vs. Coupled inductors vs. Transformer?
2 Answers. The core in a fly-back transformer has a much higher reluctance. This can be achieved in a number of ways. One is to add an air-gap to a core. Another is to use a core with a "distributed air gap", and a third is to use core materials that have naturally high reluctance. A distributed air-gap arises when the core consists, for ...

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 ...

Only the leakage flux stores the energy in coupled inductors, so the energy storage for the example shown in Figure 2 is associated with 50nH/phase instead of a 210nH/phase. This implies that a coupled inductor can be fundamentally smaller or/and have a higher current saturation rating, as compared to a discrete inductor.
