Based on the results, a developed hygrothermal simulation model is validated. This can subsequently be used later to identify critical operating conditions which can create lifetime-reducing microclimates on the chip level. This approach enables the implementation of a condition monitoring system based on the microclimate inside the power module.enconference paper
