Several years ago while making inductors for tuning a class E amplifier we
end up with a 4-1/2 turn inductor. The inductor used a 3F3 potcore, gapped
I think,
but it has been awhile. The inductor was driven hard but below saturation.
The problem; the 1/2 turn got HOT. Four turns or five turns were ok.
My physicist friend had an EE verify the problem 2000 miles away.
So, can anyone tell me why 1/2 turn would make such a difference in the
heating?
Thanks, MikeK
How do you make a half turn inductor?
Bill
Half a circle, as used at say 450 MHz and up (the one end is soldered to one point on a circuit board, goes straight up say 1/4", bends over 180 degrees and the other end soldered to another pad on the PC board...just like this "U" but flipped over (upsidedown U)...
