Why is my conduction loss so low—only 0.9 W?

Did you spot check the currents in your model? Your model didn’t load correctly for me because of the dependencies on non-standard Simulink toolboxes. However, I noted that your current measurement (Iabc) doesn’t have a source.

I was able to run your model by removing the dependencies and wiring the controller to the PLECS circuit. In that case I observed ~19W of conduction loss. This is for one device and doesn’t account for parallel diode losses.

In short, I cannot recreate your results and so you will need to provide a better explanation of what you are observing and test procedure, noting the libraries that I have available to assist you.
