About this document
Scope and purpose
The base of a power electronic design is the interaction of power losses of an IGBT module with the thermal
impedance of the power electronic system.
With a precise model the system can be designed for high output current without exceeding the maximum
junction temperature limit and being reliable in terms of power cycling, respectively.
To meet the requirement Infineon has optimized the measurement method.
The following sections describe how to thermally characterize a power electronic system and how to model it
for application oriented investigations.
