3-phase inverter thermal modeling

All,

I'm looking for some regarding inverter thermal modeling with matlab/simulink/simcape - I just found pmsm with thermal model but not inverter thermally modelled, or ThreePhaseDiodeRectifierModel - is there any resources on two level 3-phase inverter modelling?

Simscape Electrical is well suited for electro-thermal simulations. The discretes in Simscape Electrical (IGBT, MOSFET, etc) have the optional thermal port. Some composite converters also have the option to enable thermal effects:

For an example that shows how to analyze the performance of a liquid cooling system for a three-phase inverter check this:

If you’re working at the converter level and do not want the individual switching devices, the good news is that the Average-Value Voltage Source Converter (Three-Phase) block also has the option to enable the thermal port of the block and model thermal parameters:
