What is the inductance of a transformer?

The magnetizing inductance, L m, of a transformer is easily understood as the inductance seen at the primary coil winding, Lm= N 1 2/ℜ c(core). Τhe assumption for calculating L m is that the magnetic flux flows primarily in the magnetic core, which is true only for infinite permeability cores.

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.

What is the physical structure of a transformer?

Two or more wire windings placed around a common magnetic core is the physical structure of a transformer. It’s electrical purpose is to transfer power from the primary winding to the other windings with no energy storage or loss. For HW# 1 show the B-H curve for a transformer with transferred and core loss energy indicated.

Is a filter inductor a true transformer?

r a true transformer, but not for an inductor. The large amount of energy that must be stored in a filter inductor or flyback transformer is in fact stored in an air gap (or other non-magnetic material with Mr = 1) in s

How to minimize leakage inductance in a transformer?

Switching transition times are governed by transformer leakage inductance as well as by transis-tor and rectifier switching speeds. Thus it is impor-tant to minimize leakage inductance by using cores with long, narrow windows, and by interleaving the windings.

What is mutual inductance?

Mutual inductance (magnetizing inductance) rep-resents energy stored in the finite permeability of the magnetic core and in small gaps where the core halves come together. In the equivalent cir-cuit, mutual inductance appears in parallel with the windings.
