Abstract
IGBT modules are one of the main components subjected to failures in high power converters for wind turbine applications. This Master thesis deals with the analysis, design, implementation and validation of a power cycling test setup for accelerated wear-out and lifetime investigation of high power IGBT modules. The setup is able to test 10 PrimePACK3 IGBT modules with DC current up to 2000A, providing a wide flexibility on its operating conditions. The gate signals control, data acquisition and monitoring systems have been developed in NI LabVIEW. In addition, two methods for junction temperature estimation based on datasheet parameters have been implemented. Currently, the PrimePACK — 3 IGBT module from Infineon (FF1000R17IE4) is being tested and the obtained results are depicted in this report.
