Coupling equations
Shown below is a virtual lossless transformer. It is used to simulate real electric transformers for coupling effects in electroacoustics.
The equations which describe the behavior of an ideal transofrmer are:
(5)
(6)
where
and
represent the number of primary (subscript
on schematic) and secondary (subscript
on schematic) windings.
Attention : Caution
The electrical impedance :
at the input of a transformer depends of the impedance at the output:

An illustration of the ideal transformer is given in this lecture and here.
