IGBTs at Higher Operation Temperature Impact on inverter design
The development of IGBT power modules has always been characterized by the
continuous increase of the power density for cost reduction and design optimization
of the complete frequency converter system [1]. The requirement of higher power density
is directly associated with increased current per chip area and therefore an increase of
the junction temperature during the operation is expected.
