Detection of a failure of a power module based on operating conditions

A device configured for detecting a failure of a power module, the device comprising:

• a memory storing at least one model comprising regular temperature values associated with different operating conditions of the power module, the regular temperature values of the at least one model represented by at least one first predetermined curve and at least one second predetermined curve that is different from the at least one first predetermined curve;
• a module for acquiring at least a first temperature value from a first temperature sensor located in the vicinity of the power module;
• a processor configured for:
• checking whether the at least one stored model is up to date, determining that the at least one stored model is not up to date, and replacing the at least one stored model with an updated version thereof after determining that the at least one stored model is not up to date;
• determining current operating conditions of the power module;
• comparing the current operating conditions and at least the first temperature value with the at least one stored model;
• based on the comparison, determining a failure of the power module.
