Ideal Transformer
Purpose
Ideally coupled windings without inductance
Library
Electrical / Transformers
Description
This component represents a transformer with two or more ideally coupled
windings. At all windings , the voltage
across the winding divided by the
corresponding number of turns
is the same:
The currents of all windings multiplied with the corresponding number of turns
add up to zero:
In the transformer symbol, the first primary side winding is marked with a little
circle. The orientation of the other windings is indicated by a dot. Use the Polarity
parameter to change the orientation of a specific winding. This is equivalent to
making the corresponding number of turns negative.
Parameters
- Number of windings
- A two-element vector
containing the number of windings on the primary side
and on the secondary side
. The default is [1 1], which represents 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.
- Polarity
- A string consisting of one + or - per winding specifying the winding polarity. A single + or - is applied to all windings.
