Abstract: IGBT power modules have been equipped with temperature/humidity sensors and integrated into a power converter system from the wind-power application. While exposed to climatic cycles, the power converter has been tested power-in-the-loop in a climate chamber. The test profile is a sequence of actual stress conditions recorded in a wind turbine converter operating in the field.During the tests, the internal conditions of the power modules and the power cabinet have beenmonitored. The resulting microclimates are examined when varying electrical loads coincide with climatic cycles.

Abstract: Recently transition from Si-IGBT module to SiC-MOSFET modules in the railway application is ongoing. Although humidity issue is one of the main concerns, humidity robustness of high voltage SiC modules has not been well investigated. In this paper, acceleration factors of the HV-H3TRB test on 3.3 kV SiC-SBDs are investigated. This investigation is based on varied condition of temperature, relative humidity, and voltage. Also, the result is compared with that of HVIGBT.

   Load Profile Based Reliability Assessment of IGBT Module in Full-bridge DC/DC Converter for Fast Charging of EVs

Abstract: EV Fast chargers are crucial to alleviate the driving range anxiety for E-mobility applications. A typicalconverter load profile consists of a short high-current pulse to rapidly refill the EV battery followed by a cooling-off period once the charging is completed. Power electronic components experience thermal cycles as a result, which can hasten the degradation of such components. In this context, the reliability evaluation of the power electronic converters enabling fast EV charging is of importance.This paper presents the reliability assessment of the IGBT module in EV Fast chargers to show how the load profile of the charger impacts the device's lifetime.
