Dialog Settings
� «Inductance [H]»
The Linear Inductor is selected. Common parameter type. Enter a numerical value, a variable,
or an expression in the text box or use the pin to connect a quantity. You can also specify an
initial current.
� � «Use pin»
If the box is checked, the inductance is defined by the quantity connected to the pin, otherwise
the value in the text box is used.
� «Nonlinear i=f(psi)»
The Nonlinear Inductor is selected. Open the characteristic dialog or use the pin to define a
characteristic. You can also specify an initial current. See also “Separate Component Characteristic”
on page 297.
� � «Use pin»
If the box is checked, the inductor is defined by the characteristic connected to the pin, otherwise
the settings in the dialog .
� «Nonlinear L=f(i)»
The Nonlinear dual Inductor is selected. Open the characteristic dialog or use the pin to define
a characteristic. You can also specify an initial current. See also “Separate Component
Characteristic” on page 297.
� � «Use pin»
If the box is checked, the inductor is defined by the characteristic connected to the pin, otherwise
by the settings in the dialog .
«Initial Value [A]»
The initial current is valid for all types of inductor. Enter a numerical value, a variable, or an
expression in the text box to define the initial current or use the pin to connect a quantity.
The value is set only once at simulation start.
� � «Use pin»
If the box is checked, the initial current is defined by the quantity connected to the pin, otherwise
the value in the text box is used.
� «Output Pin»
If the box is checked, the component provides an output pin of the inductance value for connecting
with a Mutual Inductance. You cannot use the normal parameter pin in this case because
the mutual inductance requires an pin with the direction attribute input.

The 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 resistance
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, the expression must be technically meaningful. If it is not, numerical instability or
completely wrong results are possible.In particular, sudden changes in the first derivation of
the control quantity should be avoided.
