| Abstract |
As environmental conditions influence the lifetime of power semiconductors, understandingmicroclimates inside converter cabinets is indispensable. We present data from railway converters andobserve dynamic humidity during operation. The results are explained by moisture diffusion in plasticsand validated by simulation and lead towards refined requirement specifications for powersemiconductors. |
