in Model partitioning by JunHwan Choi (13 points)

Hello,

I am currently trying to simulate a Three Phase Permanent Magnet Synchronous Machine (Open Winding) driven by two Three Phase Inverters. The circuit I have configured shares a DC power source, and I am also analyzing the common mode current.

The issue I am facing is that when I configure the circuit in this way, I encounter the following error:

Power Electronics Converters utilization: 6 out of 3 200.0%

Since I am using the Typhoon HIL 402 with configuration number 5, where the maximum converter weight is 3, I interpret that using two three-phase inverters exceeds this limit.

Previously, I have simulated two three-phase inverters using the same HIL device with Core Coupling to control two independent motors. Is there any possible solution to resolve this issue in my current situation?

Thank you.

Hi JunHwan,

As you mentioned your are using HIL402 device with configurations 5, which basically provides 2 cores for running converters and since one core can run a maximum weight of 3, you have sufficient core available to run both inverters. However, since 2 converters will use 2 cores, without core-coupling, you cannot compile the model since the processor is trying to run both converters on a single core. Hence, I recommend you to kindly use core coupling in the model preferably at a suitable point between the converters.
I also would suggest, since there is only a single machine block in your model, you can try to use configuration 1 of HIL402 also. With addition of core-coupling, your model will compile in configuration 1 as well.
In case, you still face any errors, try to share relevant files of the model, if possible, for better understanding.

Best Regards.
