120 Modeling with Circuit Components
Equivalent Line (TRIACEQUL):
The TRIAC characteristic is defined by an Equivalent
line. You have to enter a value for the Forward voltage,
Bulk resistance and Reverse resistance.
Vlimit stands for the intersection of the forward and reverse
characteristic and is calculated by the program itself.
Exponential Function (TRIACEXP):
The TRIAC characteristic is defined by an Exponential
function. You have to enter values for the Saturation
current, Thermal voltage and Reverse resistance.
XY Data Pairs (TRIACXY)
The thyristor characteristic is defined by a data table. You can define the table within the
characteristic dialog directly or load an existing file. The data pairs are displayed in the lookup
table and used for the characteristic. You can modify the data when necessary. See also
“Separate Component Characteristic” on page 297.
� «Element Name»
The characteristic of the TRIAC is defined by a characteristic component. Characteristic parameter
type. Enter the name in the text box (e.g. XY1.VAL, EXP.VAL) or use the pin to connect
the characteristic component. The internal used type is TRIAC.
� � «Use pin»
If the box is checked, the name is defined by the quantity connected to the pin, otherwise the
name in the text box is used.
«Control Signal»
Defines the TRIAC control signal. Control 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 name is defined by the quantity connected to the pin, otherwise the
name in the text box is used.
