Re: [TCML] supposedly a tesla coil

[Frosty <frosty90@xxxxxxxxx>]

While on this subject, how do we actually define a tesla coil? Most of us
will use the usual "A tesla coil is an air cored resonant
transformer....etc." However, what about 'base-feed' style coils (like high
frequency vac. tube systems) or even 'magnifiers', neither of which really
fit the classical definition of 'transformer'.
Also does the "resonant" part refer to just the secondary (the resonator as
such) or in the case of a multi coil system do all parts have to be
resonant, which would technically make regular solid state coils and vacuum
tube coils (?) nt fit this definition. It seems now that we are calling
anything with an air cored helical resonator a telsa coil.
 Noting wrong with doing this though... It seems now that a tesla coil is
defined purely by it's seondary, the rest of the circuitry (sprak gaps,
primary coils, power inverters etc) merely exists to couple power to the
'tesla coil' (the secondary). It seems that really the only thing in common
between what we all call telsa coils is the secondary....
Anyway about the article......really does it matter if they refer to it as a
'tesla coil', many of us (the 'high-voltage community') have in the past
(althogh not really anymore) refered to setups such as ignition coils,
flybacks etc as tesla coils, even thought they arent resonant and really
share nothing in common with the 'regular' tesla coils.
Anyway thats my two cents!

Cheers,
Jesse
