Mutual Inductor
Mutual inductance.
Description
The Mutual Inductor block represents the mutual inductance described by the following equations:
Where:
-
- voltage on winding 1;
-
- voltage on winding 2;
-
- primary winding current;
-
- secondary winding current;
-
- winding inductances;
-
- mutual inductance;
-
- mutual induction coefficient, ;
-
- Time.
This block can be used to represent an AC transformer. If the effects of inductance and mutual inductance are not important in the model or are unknown, you can use the Ideal Transformer block.
Each of the two electrical networks connected to the primary and secondary windings must have its own Electrical Reference block.
Ports
The block has four electrical ports. Polarity is indicated by the characters + and - . Ports labelled 1+ and 1- are connected to the primary winding. Ports labelled 2+ and 2- are connected to the secondary winding.
Parameters
Inductance L1 - inductance L1
10 Gn (by default) | scalar | positive
Own inductance of the primary winding.
Inductance L2 - inductance L2
0.1 Gn (by default) | scalar | positive
Own inductance of the secondary winding.
Coefficient of coupling - coefficient of mutual induction
0.9 (by default) | scalar | positive
Mutual induction coefficient, which defines the mutual inductance. The value of the parameter must be greater than 0 and less than 1.
Initial value of primary current i1 - initial value of primary current i1
`0 (By default)
Initial value of primary current .
Initial value of primary voltage v1 - initial value of primary voltage v1
`0 (By default)
Initial value of primary voltage .
Initial value of secondary current i2 - initial value of secondary current i2
0 (By default)
Initial value of secondary current .
Initial value of secondary voltage v2 - initial value of secondary voltage v2
0 (By default)
Initial value of secondary voltage .
