The component represents the mutual coupling between two inductors, L1 and L2, quantitatively
determined by the factor k.
The mutual inductance is equivalent to the present value of the quantity specified in the text
box. For the quantity any numerical value, variable, mathematical or logical expression can
be used. Usually a Constant value, a Time function or a variable are chosen, or the value of
the inductance is determined in a state graph. A mathematical expression must conform to
the syntax of the SIMPLORER expression interpreter. All system quantities and variables can
be combined with mathematical and logical operators and constants.
However, if the value of this quantity is unstable, numerical problems can occur. In particular,
sudden changes in the first derivation of the control quantity should be avoided.

«Inductance L1/L2 [H]»
L1 and L2 hold the names of coupled inductances. Quantity parameter type. The type accepts
only an inductance parameter (e.g. L1.L, Name.L). The values cannot be assigned by a variable.
Enter the quantity of a inductance or use the pin to connect the quantity.

If the box is checked, the inductances are defined by the quantity connected to the pin, otherwise
the value in the text box is used.
«Mutual Inductance»
K/M is the factor which quantitatively determines the mutual inductances. Common parameter
type. Enter a numerical value, a variable, or an expression in the text box or use the pin
to connect a quantity.
� � «Use pin»
If the box is checked, the coupling factor or M is defined by the quantity connected to the pin,
otherwise the value in the text box is used.
