Abstract:
This paper details the results of comprehensive experimental reliability tests performed on industrial IGBT modules. Main goal of this study was to investigate the main failure modes for power cycling tests that were superimposed with passive thermal cycles and to compare them with the failure characteristic of standard power cycling and passive thermal shock tests. In addition, a lifetime model was derived on the basis of the standard power cycling tests and compared with the results of the superimposed power cycling tests.
