Electrical Model
only its current gain BN0 is available as parameter of the IGBT model. The internal model of
the free wheeling diode (FWD) is similar to that of the single diode.
You can define five simulation levels for the electrical and three simulation levels for the thermal
behavior. Each level combination has a certain set of parameters. The values of them can
be defined in the model dialog. The component outputs are true of all types of the IGBT models.
They are listed at the end of the model description. See also “Thermal Semiconductor
Model” on page 126 and “Temperature, Voltage, and Current Dependencies” on page 125.
