Abstract
The present disclosure relates to methods of predicting lifetime of a power semiconductor device. According to the invention there is provided a method for predicting a lifetime of a power semiconductor device comprising of: a) obtaining data related to working conditions of the power semiconductor device; b) calculating a switching frequency with its peaks in switching cycle on a basis of obtained data; c) calculating at least one KPI, Key Performance Indicators; d) implementing received KPIs and an at least one input feature to Machine Learning model; e) estimating lifetime of the power semiconductor device by receiving total number of switching cycles that the power semiconductor device is able to perform throughout its lifetime.
