How to distribute burden on two CPUs (user and system) to address the CIO indication?

Mon, 05 May 2025 15:18:32 +0000

Hello,

I am working with Typhoon HIL 402 device (Configuration 4) to estimate the semiconductor losses in a DAB converter. What I want is to operate the converter at 50 kHz. However, when I set the execution rate to 2e-5, it gives me the indication of CIO claiming of inaccurate readings (works fine with 5e-5). I tried to utilize the memory consumption between the two available CPUs as per this link, but still the problem exists.

Now I am not sure whether I am doing the utilization in the correct way. Any advice, comment regarding this is highly appreciated.

Another doubt is whether the semiconductor loss estimation of Typhoon HIL accounts for the switching losses as well, if then, do I need to have a really small time step to capture the switching operation of the devices? Is this possible in a HIL 402 device?

Thanks

Is it possible to adjust the size of a core coupling element?

Hello,

Is it possible to adjust the size of the core coupling elements so that the spacing between the connectors is equal to the spacing between the modeling elements?

E.g., the spacing between the connectors of a four-phase core coupling element is significantly larger than the spacing of between the phases & neutral (A,B,C,N) of the Grid component in the Microgrid library. This situation creates strange routings of connections between the modeling elements.

It seems that the size of coupling elements is not adjustable.

Any hints?

Is there any way to use 2 Three phase inverter with Three Phase Permanent Magnet Synchronous Machine (Open Winding)?

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.
