In LTspice, the magnetizing inductance represents the unity inductance (N=1), and then the primary and secondary are determined through the help of an ideal transformer made of a VCVS and a CCCS, each (see the #4th picture in your ltwiki link). The turns are determined through the values of these sources.

Further to shy away from the usage of transistors as gain devices. This to the extent that new technology is generally avoided. LTspice Component Library.

The source is a three phase TN-S (wye) connected. Then I wanted to add a 1:1 isolation transformer (wye/wye), but I cant get the output voltage to match 1:1 with the input voltage. “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).

This to the extent that new technology is generally avoided. LTspice Component Library.

Your inductance ratio is 50/.15 = 333.3, so the turns ratio is the square root of that, or 18.26. This makes your output voltage 18.26 × 12V = 219V. Depending on their size, real transformers would have values about 1/10 to 1/100 of what you used, but for modeling purposes, it isn't all that critical.

The best way would be to draft a model with coupled inductors with a mutual inductance statement placed as a SPICE directive on the schematic. See the section on mutual Inductance for more information. Inductors participating in a mutual inductance will be drawn with a phasing dot.

SPICE Model of Current Transformer 1. Summery : current transformer
A current transformer (CT)
usually used for measurement of currents (especially large values)
when large values of current are expected, a CT reduces current proportional to the current in the circuit (primary current).
Modeling Concept:
Use the secondary side of a ‘voltage’ transformer model as Hi In LTspice, a transformer is basically two coupled inductors.

One item that can be tricky to model in Spice is a transformer. You won’t find a transformer in the components section of LTSpice. Instead, you’ll have to build one out of inductors.

Note that the primary and secondary series resistance is added to. L1 and L2 in a definition statement and does not show. The schematic below is the model structure of the Coilcraft advanced power inductor model. This may differ slightly between series and is different from the RF or Design tools - inductors - LTspice ▻Download libraries for Unix and Windows, history and read me.

In order to make this we need three inductors L1, L2, and L3. with Gabino Alonso, Strategic Marketinghttp://video.linear.com/93?utm_source=LTspice&utm_medium=video&utm_campaign=youtubehttp://www.analog.com/en/design-cen Trying to simulate saturable coupled inductors/transformers in LTspice for some current sensing project, but seems like I can't couple arbitrary inductors.

Jan 21, 2019 You probably mean a small-signal DC transformer, for use in .AC analysis. If so, the basic configuration is a current source at the input,

The turns are determined through the values of these sources. There is not a build in AC Transformer in LTSpice Analog. You just need to use two inductances, coupled with a Spice instruction. Please check this and this links from Analog.

Can LTspice model those?
