Dear
Alberto,
until now I have used the rule that the primary of such
a loop
transformer should have the same inductivity as the loop
itself.
In the design used in the picture I feel
that
the
inductivity of the "primary" can be controlled by the AL value of the
ferrite
only. This may result in less freedom in the design.
But I do not
have any
practial
experience so far, and to answer your question I
had to
build the two transformer variations and test them. I would not
dear to
answer merely by theoretical considerations.
OK?

I would like especially to comment on using a one
winding loop combined with a step-up transformer:
I am interested in knowing opinions about using the loop itself as
a primary of the transformer, as in this picture (heavily
compressed
to stay into the size limits). Here it is a three-turn loop, but it
could
be a single turn one, as discussed.
