The component represents an electrical conductance. Within the dialog you can choose a linear
or voltage-controlled conductor type.
Dialog Settings
� «Conductivity [S]»
The Linear Conductor 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.
� � «Use pin»
If the box is checked, the conductivity is defined by the quantity connected to the pin, otherwise
the value in the text box is used.
� «Nonlinear G=f(v)»
The Nonlinear voltage-controlled Conductor is selected. Open the characteristic dialog or use
the pin to define a characteristic. In addition, you have to specify a control component (quantity).
See also “Separate Component Characteristic” on page 297.
� � «Use pin»
If the box is checked, the conductor is defined by the characteristic connected to the pin, otherwise
by the settings in the dialog .
«Control Component»
Define the control component (quantity). Quantity parameter type. The type accepts only a
voltage of a circuit component (e.g. E1.V, Name.V). The values cannot be assigned by a variable.
Enter the voltage quantity of a circuit component or use the pin to connect a quantity.
� � «Use pin»
If the box is checked, the control component is defined by the quantity connected to the pin,
otherwise the value in the text box is used.
Linear Conductor
it () =
G⋅v() t
The conductivity 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.
