I have not gotten the AC controller anywhere near that output. These numbers are a bit of a guess. 400V seems reasonable for the max voltage of the IGBTs. 1200A per phase is more heat than is likely possible to transfer out of the IGBT to the heat sink and out to the glycol. But it should put that out for a little while.

What about the software ? do you have a current limiter by soft ? .Have a video to see the use of the software ?

There is a hardware limit, and a software limit. I have to dig out the test video to refresh my memory. I think I hit the hardware limit when it was adjusted as low as it would go - maybe - 350A or so?
The hardware limit is not easy to calibrate. I was expecting the limit to be at least 400A.
