Why SIMULINK circuit and SIMCAPE circuit don't give same results?

Hello Community!!

I'm trying to simulate a T-Type NPC PFC rectifier (yes, I know here at MATLAB exchange we have the VIENNA example but that is a Y-switch Rectifier...just saying~), I designed the 12 switch T-NPC exactly the same (valies and all) on each platform: SIMULINK and SIMSCAPE (attached).

I assume both approaches should have the same way to solve and generate the same result waveforms but as you might see on both of them the resuls are not even close.

Am I doing something wrong with SIMSCAPE that makes this difference? The circuit in SIMULINK is satisfactory, is it possibole to migrate it to SIMSCAPE somehow with some App (just to confirm I didn't make a mistake on it)?

Thanks

Yoo-hoo!—Is anyone there SIMULINK Staff??

There is no functionality available to convert models between the two technologies. Would be good to consider one technology only and validate the results against the theory. If the results are not as expected I suggest double checking connections and parameterization of different blocks. For instance, in the Simscape model I can see that connection between a, b, and c phases are mixed up in the VI inv sensors and VI grid sensors but other issue that are not so easy to spot may hide in the model.
