Power converters represent one of the highest failure rates in the wind turbine. Therefore
converter manufacturers perform burn-in tests to prevent shipping of faulty converters.
Recent developments in junction temperature estimation, based on accurate online IGBT
collector-emitter voltage measurements, allow for thermal stress estimation of the IGBT
modules. This is utilized to detect infant mortalities in power converters, by comparing
thermal responses of IGBTs for faulty and non-faulty converters. The method proves to be a …
