its blocking capabilitywhen it is operatedwith this value. Thus subsequently no negative
voltagemay bepresent at thediode.
5.5 Brakechopper (PIM/CIBmodules)
For PIM/CIB modules there can be further information found regarding the maximum
permissible and characteristic values of abrake chopper if implemented.
The layout and contents of this datasheet section resembles that of the inverter IGBTs
as well as the associated freewheeling diodes (chapter
therefore not bedescribedagain here.
Data regarding themaximum permissible and characteristic values of the brake
5.6 NTC resistor (optional)
If the module contains an NTC resistor to determine the baseplate temperature then
associated data regarding the characteristics of that resistor can be found in the
The determination of the nominal resistance at 25°C (rated zero power resistance R
is carried out at ameasuring power which effects only aminimum of self-heating of the
NTC resistor and, with respect to the true measuring tolerances, may be ignored (i.e.
the measuring current is appropriately low). The B or
values are specified based on
the nominal resistance R
. These describe the gradient of the resistance against the
