I am making an average model of 2 level SST with DC bus as output. The cells are a combination of CHB and DAB. When I am trying to simulate it is giving this error with respect to the input side of CHB. The same model works well in Simulink. How to solve this?
Link for the model
It looks like your control is unstable. It’s not clear why that is. Since you have a model working in Simulink, indicating there may not be something fundamental driving the instability, perhaps there is an implementation error such as a flipped measurement or math operation in the model.
I would suggest reducing the model complexity, analyzing a simpler system, and benchmarking subsystems against a similar subsystem in your Simulink model to see where the error is introduced.
By the way, in the future you can post your *.plecs model directly. When we first transitioned to the new forum we blocked certain attachment types but this should be resolved. Please let me know if there’s any issues!
Thank you for the reply. I will check the model part by part and see. About uploading model, I was not able to find any option for direct attachment probably because I am new here. Next time I will try to directly attach the model.
