110 Modeling with Circuit Components
Equivalent Line (IGBTEQUL):
The IGBT characteristic is defined by an equivalent vt () – Vf I = --------------------- for v() t ≥ V
line. You have to enter a value for the Forward voltage, R limit
b
Bulk resistance and Reverse resistance.
vt ()
I = --------- for v() t < V
Vlimit stands for the intersection of the forward and re- R limit
r
verse characteristic and is calculated by the program itself.
Exponential Function (IGBTEXP):
The IGBT characteristic is defined by an Exponential
function. You have to enter values for the Saturation
current, Thermal voltage and Reverse resistance.
XY Data Pairs (IGBTXY)
The IGBT 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 IGBT 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 IGBT.
� � «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 IGBT control signal. Control parameter type. Enter 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 characteristic connected to the pin, otherwise
the name in the text box is used.
