 Hi, Malcolm


<SNIP>


it is derived from Conservation of Energy.

    0.5CpVp^2 = 0.5CsVs^2   where Vp = gap firing voltage

=>  Vp^2*Cp/Cs = Vs^2

=>  Vp*SQRT(Cp/Cs) = Vs

In other words, you can't get more out than you put in and that
equality assumes no losses in transferring the energy from primary to
secondary. Note that it also works by Vs = Vp*SQRT(Ls/Lp) since
LsCs = LpCp (tuning requirement).

Ok, But what about the resonance of the coil.  You get the first 50Hz pulse
then, the next pulses are whole due to the EMF charging the capacitor up.
Surly this is free energy ?

Chris.





All the beST,
Chris.
