Hi,
A little head-up on your task.
I see that you are calculating the efficiency by using Simulink blocks. Even though theoretically correct, you may want to explore a post-simulation function that is [efficiency, lossTable] = ee_getEfficiency('loadIdentifier',node,startTime,endTime). Please, refer to the doc page: https://www.mathworks.com/help/sps/ref/ee_getefficiency.html?s_tid=doc_ta
You'd need to enable Simscape logging first, then execute the function making sure that you pick startTime and endTime when you're system is in steady-state.
The good thing about using that function with the IGBT (Ideal, Switching) block is that it reports on conduction and switching losses separately enabling your aging studies especially on the switching losses.
FYI, this topic is covered in the training course I authored: https://www.mathworks.com/learn/training/power-electronics-control-design-with-simulink-and-simscape.html
Hope this helps,
