Re: [TCML] Coupling

I'm not a builder, only hanging out hoping for osmosis to kick in.

But I did burn holes in myself with transformers before I could spell em --and I think...


That's a hot idea of simplistic flexibility.


If not for the desired aim, then surely for some form of optimization via tweak.


p.s.  Really I'm more of a divide-and-control thinker/solver, but the idea reminded meself too of a sorting algorithm where two choices in a list are made to divide the section that is more-correct into a thirds, rather than binary halves.

And if you want to balance against a floating, untapped virtual center point somewhere in a long winding, then what better principle than to balance the physical lengths with adjustable taps as a first order calibration before the machine is test-worthy.  I love the new trick!  Like a new programming pattern for a coder :)  Here me purrr.

Hi All

With a bipola coil would having 2 movable tap point work for changing the coupling ?

Say the coil need 5 turns to be in tune, you could built the primary with 10 turns and you could move the inner and outer taps points in or out but still keeping the 5 turns needed to keep the coil in tune, the inner and outer turns passed the tap point would be electrialy dead so to speak.

Thoughts on this one guys.

Hi Kurt,

Splitting and separating the secondary seems like a great way to vary the coupling, but one must also bear in mind that doing that will vary the Lsec inductance and tuning.  I can't think of a way to vary only the coupling on
a bipolar coil, but I have never built one.

...just my 2 cents: cutting the bipolar secondary in 2 independently
halfs could enable the control of the coupling (see the ASCII-sketch):
