TE>> Given the frequency, coil size, and number of turns, find the
TE>> inductance. Then calculate the capacitance that is needed to make the
TE>> LC secondary circuit oscillate at the desired frequency.
TE> hmmmm? Usual secondary has no capacitors, per se. Soem model it as
TE> the inductance and teh stray capacitance. Some treat it as a helical
TE> resonator. The second apprach is the one i fancy, as do the Corum's.
Your explaination of the way to go about "designing" a Tesla coil
is excellent. How many have you made ? :-)
TE> Matching [the primary] to power transformer secondary is nice, but
How would one actually achieve this ?
TE> I reccomend TC TUTOR, by the Corum brothers, runs on a PC. There
Where would I buy this program from ?
TE> are other desing sw packages that may be of assistance. For
Can you give us a short list of the software thats available ?
TE> understanding Corum's Vacuum Tube Tesla Coils is good. Poor title
TE> as it is about key elements of ALL coils.
I've seen others reference this book (e.g Richard Quick). Is it
available in "good technical book" stores or must I go to some
specialist shop only ?
TE> DO not skimp on secondary wiore size. #22 is ok. Some do #30. Too
An acquaintance of mine wound a coil by winding two wires onto a
former next to each other (these's a special term for that -
can't remember). When fully wound he placed the coil upright then
let one of the ends go. In very short time he had a coil with
neat spaced out turns ! (and a lot of useless wire at his feet) A
layer of epoxy finished it off. He gets a 3 foot arc from 8Kv
input. The secondary is about 4 feet high and 10 inch diameter.
TE> Consider making mechanical arrangements for a tertiary coil...
Are you talking here about a "magnifier" coil ?
