AC DC Theory and Thoughts.
In theory, in an AC TC circuit the capacitor should be sized correctly so it
will reach a full charge at the peak of the AC wave cycle. The spark gap
should be adjusted so it will discharge at or near a full capacitor charge.
If the cap is too large it will not reach a full charge and power output
will be low. If the cap is too small the discharge current will be low and
power output will be low.
By using full wave DC instead of AC you no longer have to deal with the
problem of having to be so exact in sizing the capacitor used in the
circuit. With DC the amount of charge in the capacitor will depend on the
spark gap. The spark gap can be adjusted to give maximum charge on the
capacitor and maximum power output. The capacitor will not discharge threw
the spark gap until it has reached a full charge.
In theory the capacitor in a TC circuit could be doubled in size. The
charge rate of the capacitor would be longer and the output current will be
doubled. A coil that was producing 24" sparks from a single neon should now
produce 48" sparks from the same neon. As we all know doubling power will
not exactly double discharge spark length but you get the idea.
We all know from experience if you double the power supply size, double the
capacitor size, the coil will now produce much longer discharge sparks. If
you can double the cap size but don't have to double the power supply size
because the cap charges slower and discharges twice as much current as
before the results should be longer discharge sparks. The cap is no longer
required to charge at 60 Hz, it can now charge at any frequency you like.
Consider this thought. What if the capacitor were adjusted to discharge at
a some harmonic frequency of the Tesla Coil will that affect the resonance
rise?
This idea came to mind after reading a post about DC coils.
What do you all think?
