Javatc update



Original poster: "Barton B. Anderson" <bartb@xxxxxxxxxxxxxxxx>

Hi All,

I put up another small update to Javatc.
http://www.classictesla.com/java/javatc.html

The addition is a C reference to the tank cap size needed (for the inductance calc'd) to resonate the primary circuit at the secondary frequency.

The primary cap size entered as an input is the "actual" cap size which is used for various outputs. Sometimes because a coiler doesn't know what to use for any given inductance, a reference is handy (it is only a reference). You still need to enter a cap size in the inputs if you want to calc certain outputs. However, you could just leave the primary cap size blank, calc the circuit, reference the new C output, then enter the reference C value, and recalc. This way, your not wasting time recalculating (or worse, guessing).

Javatc does not "dictate" inputs, including C. This gives coilers freedom to play with various scenarios and is why this type of thing is only a reference. For example, I run my coils detuned a few percent high on inductance, and I need freedom with C and L.

The equation used:
C = 1 / (4 x PI^2 x F^2 x L),
where,
C = Size needed to meet (Sec Freq = Pri Freq)
F = Secondary Frequency
L = Primary Inductance

The download pc version is of course updated as well.

Take care,
Bart
