Description

[Picture] [Picture]

This component represents an transformer with two or more ideally coupled windings. At all windings w, the voltage vw across the winding divided by the corresponding number of winding turns nw is the same:

v1   v2   v3
n1 = n2 = n3 = :::

The winding currents iw of all windings multiplied with the corresponding number of winding turns add up to zero:

0 = i1 n1 = i2  n2 = i3  n3 = :::

In the transformer symbol, the first primary side winding is marked with a dot. All windings have the same orientation. To change the orientation of a specific winding w make the corresponding number of turns nw negative.

Parameters and Dialog Box

Width
The width of the electrical ports resp. the number of ideal transformers represented by the component.
Number of windings
A two-element vector [w1 w2] containing the number of windings on the primary side w1 and on the secondary side w2. The default is [1 1], which represent a two-winding transformer with opposite windings.
Number of turns
A row vector specifying the number of turns for each winding. The vector length must match the total number of primary and secondary side windings. First, all primary side windings are specified followed by the specifications for all secondary side windings.
