The ability to access energy at the flick of a switch makes life much easier. People it was in a vacuum because there would be no air resistance acting on it, and so no energy would be transferred from any of its energy stores. There would be no net change to the energy stored in the system. Because of this, it would be an example of a

6 FAQs about [The air switch of the box transformer shows that there is no energy stored]

Is a primary switch a transformer?

Although we call it a transformer it is not actually a true transformer, but more an energy storage device, where during the period of time when the primary switch is on energy is stored in the air gap of the core, and during the off time of the primary switch, this energy is transferred to the outputs.

Do Transformers store undesired energy?

In practice, all transformers do store some undesired energy: Leakage inductance represents energy stored in the non-magnetic regions between windings, caused by imperfect flux coupling. In the equivalent electrical circuit, leakage inductance is in series with the windings, and the stored energy is proportional to load current squared.

Is a flyback transformer a switched inductor?

The flyback transformer is a misnomer and ought to be considered as a switched inductor with coupling, as it does store energy unlike an ideal transformer. However the addition of a small air gap allows more current with greater H fields now occupied in the air gap Not all the energy is in the gap but optimally it can be 2x as much as in the core.

Why do you need an air gap for a flyback transformer?

Air gaps are usually used for safety considerations. For a flyback transformer, you do not want arcs between the primary and secondary winding, and use an air gap. He's talking about core gapping, not isolation between windings. By clicking “Post Your Answer”, you agree to our terms of service and acknowledge you have read our privacy policy.

Why does a transformer have a gap?

Imagine them with bobbin. A gap is necessary to increase the energy storing capability of the transformer - it tilts the B-H curve - but more importantly, it stabilizes the inductance by making it independent from the material permeability. Yes, you are right @VerbalKint . The main event in the transformer is the airgap.

How does a transformer work?

The transformer uses a standard RM10/I core set and bobbin. The windings are interleaved – the primary split into two half primaries, with all other windings sandwiched in-between. A twisted bundle is used for each half primary, comprising 15 strands of 0.1-mm wire, with each half primary wound over a single layer. Figure 35.
