Simulink simscape Synchronous reluctance machine model with added grid and rectifier instead of battery

2 views (last 30 days)
I am working with the model https://se.mathworks.com/help/physmod/sps/examples/synchronous-reluctance-machine-torque-control.html and want to add grid and rectifier instead of the battery present in the model. My problem is that when the motor start to draw current the DC voltage on the dc-link will start to fall. Even if I put a higher the capacitor value it will still fall just slower. Can anybody tell me what I am doing wrong or which parameters I should look at? (see attached picture of model)

Can you please attach your model file (.slx)? This will help in reproducing the issue as you might have made some changes to the parameters and model configurations of the example model. This will also provide information about the parameters of the new blocks you have added.

Thanks for answering, the file is attach. I actually fixed the problem myself, if I put use fixed-cost runtime consistency iterations off in solver configuration (connected to the mechanical circuit) it can hold the voltage. Can you tell me why this is?

Just some Matlab Answers cleanup. Daniel solved the problem:
