The System level IGBT (Insulated Gate Bipolar Transistor) model is used to simulate a static
voltage-current-relation. Each voltage cause a corresponding current depending on the selected
characteristic.
The IGBT types of predefined characteristics defined within the component dialog guarantee
a high calculation speed. In contrast to the predefined characteristic types (equivalent line,
exponential function) you can use each other separate characteristic from the Tools folder or
an appropriate quantity of a component. Usually an Equivalent line, Exponential function,
Hyperbolic function, Polynom or the XY Lookup Table should be used. Characteristics based
on XY-Data pairs allow simple access to measured curves for the switching behavior of the
components.
To control the IGBT, a logical signal is applied. This signal can originate from any SIMPLOR-
ER system variable.

� «Characteristic Type»
The IGBT type of predefined characteristics is selected. In the list, select a characteristic.
� «Type»
In the list, select the equivalent line, exponential function, or XY Data Pairs and define the
corresponding characteristic parameters. These are Common parameter types. Enter a numerical
value, a variable, or an expression in the text box.
