RE: Tesla Coil Computer Programs

Alan -

I agree that listing all of the turns in the primary coil has its advantages
and I have done this with some of my old programs. However, a lot of paper
is required to print out the program. You mentioned top load. One of the
reasons I put the top load in the JHCTES inputs is that it varies the
primary turns.

One big improvement in TC engineering progress is that today the many TC
programs and coilers calculations all produce answers that are very close in
outputs. When the JHCTES was first made available several years ago that was
not the case. There were large diferrences in outputs with other programs
and coilers calculations. The main reason is that coilers did not agree on
how the many available equations and other information should be used. Some
coilers said the equations did not work. However, that was because
parameters like coil self inductance and the toroid influences on the
secondary were not clearly understood. Some differences still exist today
when empirical data and equations are used.

 I'm a happy user of both Ross and Ed's spreadsheets. I would like to point
out that by listing all the different values of the primary at different
turns. This is a big advantage if i want to knwo where to start tapping a
primary when i'm testing out a coil for both the first time and w/
different top loads.
