抄録(英) | In the presented paper it has been proposed a methodology that translates the customer conditions in terms of electric power into thermo-mechanical variables correlated with power module failure mechanisms. An initial analysis of power module failure modes will be presented, then the module temperature during inverter load profile will be numerically estimated. The so-obtained time-temperature during inverter operation will be converted using Rainflow-like approach into a pre-defined number of loading conditions. According to the time and temperature dependency of the typical failure mechanism, the mentioned loading cases will be characterized by different temperature swing and time duration. The extrapolated equivalent history will be a starting point to set durability tests aimed to predict reliability performances. 翻訳 |
