How do I get the transformer Core Loss?

0 votes

I would like to know how to obtain the core loss used in the transformer through the PLECS program.
Also, I wonder if there is a way to check if the B-H curve of the core matches the actual B-H curve.

It's a question that's lacking, but I'd appreciate it if you could answer it.

I have attached a small model probing this core to get the core loss and BH curve using an XY plot.

If you need further assistance, please write to

Best regards,
