I am writting at my diploma thesis with an EMC theme.
If got a power fan (13V / 6A) witch produces conducted emissions, so I
have to reduce them to achieve CISPR25.
Up to 40MHz I found an easy solving with LC lowpass filter, but over
50MHz I am out of the CISPR25 limit.
Does anybody have experiences in EMC design in high frequency bands,
doesn't have?
I think about solving it like the motherboard producers do, they
design there signals like little inductors and so one.
But I didn't find any guidlines to do this like them.
