Electrical Elements
The Mutual Inductor block models a mutual inductor, described with the following equations:
where
| V1 | Voltage across winding 1 |
| V2 | Voltage across winding 2 |
| I1 | Current flowing into the + terminal of winding 1 |
| I2 | Current flowing into the + terminal of winding 2 |
| L1, L2 | Winding self-inductances |
| M | Mutual inductance |
| k | Coefficient of coupling, 0 < k < 1 |
| t | Time |
The Winding 1 initial current and Winding 2 initial current parameters set the initial current through windings 1 and 2.
Note These values are not used if the solver configuration is set to Start simulation from steady state. |
This block can be used to represent an AC transformer. If inductance and mutual inductance terms are not important in a model, or are unknown, you can use the Ideal Transformer block instead.
The two electrical networks connected to the primary and secondary windings must each have their own Electrical Reference block.
Self-inductance of the first winding. The default value is 10 H.
Self-inductance of the second winding. The default value is 0.1 H.
Coefficient of coupling, which defines the mutual inductance. The parameter value should be greater than zero and less than 1. The default value is 0.9.
Initial current through the first winding. This parameter is not used if the solver configuration is set to Start simulation from steady state. The default value is 0.
Initial current through the second winding. This parameter is not used if the solver configuration is set to Start simulation from steady state. The default value is 0.
The block has four electrical conserving ports. Polarity is indicated by the + and – signs.
