It has been released by the Working Group and published on the ECPE website. This document describes a steady-state temperature, humidity and voltage bias test for the evaluation of the behavior of non-hermetically sealed power electronic IGBT and SiC MOSFET modules for the use in rolling stock applications.
The ECPE Working Group on ´Power Semiconductor Reliability for Railway Application´ has been established in November 2017 in cooperation with the European PINTA Project in the Shift2Rail Joint Undertaking. The focus of the working group is on environmental conditions for power semiconductors used in railway application especially under humidity load incl. water condensation and chemical attack.
