I want to put some modulation onto a DC power line.
I used a suitably rated COTS toroidal DC choke and was going to hand
wind another winding to introduce the modulation. But that was tedious
given the number of turns I'd need for a reasonable ratio.
Instead, I took another similar toroid and wound some wire through both
cores, several turns and connected the two ends. Viola, a large fiddle.
It works, well enough, but how to analyse or simulate this? How many
turns? It seems to stop mattering after a few, but I'm not sure how to
do the maths on this. What are the pitfalls?
Cheers
