Selecting the right L/C ratio for tank coils

[AlienGrey]

Well according to Tesla, you would want your resonant freq to be low. From what I understand, 50khz and up will radiate magnetic energy that you cant get back into the system. Loss.  So large inductance and small capacitance would be a criteria to follow.

Morey used 31.5 khz do you see a pattern here why he used this frequency ?

   Since many different values of L/C can be used for the same frequency, how do you select the best pair for a given frequency?  I am working in the 20 to 80 khz area.

Hello buddy.
Lots of L/C can resonate at 80 khz.
You can have a 30 turn inductor that resonates at that frequency..or you can have a 200 turn inductor.
More turn = more voltage peak.

What do you need? ...You question was kind of short....What do you want to do ?
Thank you.
PS:....At resonance the square wave is transformed into PURE SINE...PERFECT SINE wave....so it is not only about the peak voltage.

Easy/cheap way to make a pure-sine inverter?

  Thanks to all here for their answers. An old ham radio guy gave me the answer I needed.  Pick the frequency you want, pick the best coil value that gives you the best Q value and then select the cap  to add.
