Re: Primary thanks

Normally if the primary is too high in frequency compared to the
secondary and the primary is already too large, people add more Cp to
bring it down to where the secondary is. If your secondary has a
small toroid compared to the size of the secondary, it sounds like
you have already tried to "up" the frequency to match the
primary. To me, this sounds like your secondary is way too large for
your power source, but at least you have room to grow. When you do
get more power, you can add more Cp and go with a more reasonable
size toroid for your secondary size. BTW, what is your power source???

I`m not sure how close I need to be to get the coil to work.
I need 0.281mH of inductance from the primary to run with a frequency
of 67.09 KHz, that's why the top load is small compared to the overall
coil size. I`v got 0.261mH of primary inductance to start with I`m just
going to run the thing and see. If I went with a bigger top load the frequency
comes down and I need more primary inductance.
