I've got to agree with Mr. Freau here. I'm sure you do to Mr. Corture
(geeze, what is a guy to do when
replying to 2 John's?). Gap losses are significant (well, until solid state
can handle all power levels).
Transformers can be signicant as well. By typical large coil sizes, coilers
use pole pigs and similar
transformers to run the bigger coils, and because of that, larger coils may
be more efficient. As far as the
secondary or primary by itself? As far as I'm concerned, this is all
speculative until proven otherwise.
