Description

pict

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

v1   v2   v3
n1 = n2 = n3 = ...

The currents iw   of all windings multiplied with the corresponding number of 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 little circle. The orientation of the other windings is indicated by a dot. To change the orientation of a specific winding w   make the corresponding number of turns nw   negative.

Parameters

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 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.
