Transformer
Purpose
Ideal transformer.
Library
Passive Components
Description
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:

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

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.
