Purpose

Magnetic coupling between two windings.

Library

Electrical / Transformers

Description

pict

This component implements a magnetic coupling between two separate windings. For both 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 terminal of the secondary winding is marked with a dot.

Parameters

Self inductance
A two-element vector containing the self inductance for the primary winding L1   and the secondary winding L2  . The inductivity is given in henries (H).
Winding resistance
A two-element vector containing the self resistance of the primary winding R1   and the secondary winding R2  , in ohms (_O_  ).
Mutual inductance
The mutual inductance Lm  , in henries (H).
Mutual resistance
The mutual resistance Rm  , in ohms (_O_  ).
Initial current
A two-element vector containing the initial currents on the primary side i1    and the secondary side i2  , in amperes (A). The direction of the initial current inside the component is from the positive to the negative terminal. The default value is [0 0].
