Passive Components

Description

pict

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 primary winding is marked with a little circle. The secondary and tertiary windings are marked with dots.

Parameters and Dialog Box

Self inductance
A three-element vector containing the self inductance for the primary winding L1  , the secondary winding L2   and the tertiary winding L3  . The inductivity is given in henries (H).
Winding resistance
A three-element vector containing the self resistance of the primary winding R1  , the secondary winding R2    and the tertiary winding R3  , in ohms (_O_  ).
Mutual inductance
The mutual inductance Lm  , in henries (H).
Mutual resistance
The mutual resistance Rm  , in ohms (_O_  ).
Initial current
A three-element vector containing the initial currents on the primary side i1  , the secondary side i2   and the tertiary side i3  , in amperes (A). The direction of a positive current is indicated with small arrows in the component symbol. The default value is [0 0 0].
