Hi Everyone,

I am getting an error “Cyclic behavior during switching” while trying to run the simulation attached.

Tried different solutions as said in the attached paper.

Could anyone help me correct the simulation file.

Regards,

Silpa

Hello, I don’t see an attachment, but did you perhaps refer to our website (https://www.plexim.com/support/solutions/146) about this topic? If that doesn’t help you would need to attach your model file for anyone to help further.

Hi again. This is actually a simple issue. You have defined the series inductance values in your line input filter as “1*e-6”, which is actually the equivalent to: 1 times the mathematical constant e (2.71828) minus 6 (resulting in a negative value). In PLECS, the syntax is “1e-6”. You need to remove the * symbol in the assignments and then the model runs.
