Re: Self-built power transformer
Hi Doug,
A much better option to improve current handling
capability is to n-filar wind the primaries. If you wind primaries
one on top of the other, they will all have different diameters and
different amounts of copper in them. Since they are not identical,
there will be a power loss associated with the differences. It
mightn't be great but it will be there.
