| Abstract |
Accurate lifetime prediction of power IGBT modules based on realistic mission profile is an important issue for power electronics systems that are used in application with high lifetime requirements. An essential challenge of the process is to determine the correct number of thermal cycles. Various counting methods are applied to extract amplitude, duration and number of thermal cycles from a mission profile. The objective of this paper is to compare different cycle counting algorithms and suggest the correct one for lifetime calculation of IGBT power modules based on the thermo-mechanical FEM analysis. |
