Ideal mutual inductor
Electrical / Passive Components
This component provides two or more coupled inductors. Electrically, it is equivalent with a vectorized Inductor. In contrast to the vectorized Inductor, this component displays the individual inductors in the schematic as separate windings.
In the symbol of the mutual inductor, the positive terminal of winding 1 is marked with a little circle. The positive terminals of all other windings are marked with dots.
If the parameter is a scalar or a vector no coupling exists between the windings.
In order to model a magnetic coupling between the windings a square matrix must be
entered. The size of the matrix corresponds to the number of windings.
is the
self inductance of the internal inductor and
the mutual inductance:
The inductance matrix must be invertible, i.e. it may not be singular. A singular inductance matrix results for example when two or more inductors are ideally coupled. To model this, use an inductor in parallel with an Ideal Transformer.
The relationship between the coupling factor and the mutual inductance
is
