Description
This component implements a magnetic coupling between three separate windings. For all windings the self inductance and resistance are specified individually. The mutual inductance and resistance are modeled as linear elements.
The electrical circuit for this component is given below:
In the symbol of the mutual inductance, the positive terminal of the primary winding is marked with a little circle. The positive terminals of the secondary and tertiary windings are marked with dots.
