| Abstract |
Traction applications is high reliability demanding for IGBT modules, as requirements are very severe
and cyclic operation causes thermomechanical fatigue. The paper reports about Ansaldo Trasporti
activity in reliability testing of high voltage IGBT stressed in typical condition of traction
applications, developed within the frame of Brite Euram RAPSDRA project. Testing facility is
described, as well as test results: solder delamination at the baseplate seems to be the first failure
mechanism to be excited.
Such result are used in order to perform “design to reliability” of traction power converters. |
