Sometimes I make from a real transformer the ideal one for low signal AC (for stabilizer) analysis. I supply sinusoidal voltage to the transformer input with 90 degree phase shift. This results in an operating voltage after the rectifier bridge. This is how I use a DC transformer for circuit research.

Leakage inductance derives from the electrical property of an imperfectly- coupled transformer as the simplified equivalent circuit in Fig. 5, with secondary constants referred to the primary and without ideal transformer isolation, w

5 Jun 2000 Transformers usually comprise two inductively coupled coils, wound around a ferrite core. The coupling between the windings is never perfect.

Mutual Inductance We will use LTspice IV to determine the mesh currents I1 and Ideal Transformers The ideal transformer shown in Figure 5 is modeled in the

One for the voltage, one for the current. For practical circuits, it is recommended you start with a coupling coefficient of 1. Only a single K statement is needed per transformer; LTspice applies a single coupling coefficient to all inductors within a transformer. The following is an equivalent to the statement above: K1 L1 L2 1 LTspice is the ideal learning tool for this purpose.

3.7 LTSpice Tips LTspice part ‘ind2’. The values of the inductors are not critical, but depend on the frequency range of the mixer. Two ideal transformers are connected as shown in the diagram below. Inductors L1, L2, and L3 are set to 10µH each with a coupling coefficient of unity. They are configured as a transformer with a center-tapped secondary.

First, a quick review of ideal transformers. An ideal transformer has no losses; all of the power in the primary appears in the secondary.

“Ideal” transformer models are usually used to make it as easy as possible for the developer and to reduce the computation time in LTspice. Only the inductance values for the primary and secondary are required here, as well as the coupling factor K (here in statement K1 Lp LS set to 1 = ideal).
