Description
Block Mutual Inductor It is a mutual inductance described by the following equations:
where
-
— primary winding voltage;
-
— secondary winding voltage;
-
— the current of the primary winding;
-
— the current of the secondary winding;
-
— the inductance of the windings;
-
— mutual inductance;
-
— coefficient of mutual induction, ;
-
— the time.
This block can be used to represent an AC transformer. If the effect of inductance and mutual inductance is not important in the model or is unknown, you can use the block Ideal Transformer.
Each of the two electrical networks connected to the primary and secondary windings must have its own unit. Electrical Reference.
Variables
Use the Initial Targets parameter group to set the priority and initial target values for the block parameter variables before modeling. For more information, see Configuring physical blocks using target values.
