JAVATC performs millions of iterations for accuracy during the total system computations (it takes time). Some smaller Tesla coils can use a vertical helix shaped primary. A cone shape, or conical primary is also very common.

On this page are listed Tesla coil formulas for a reference to those who prefer to make calculations on paper. The Tesla coil is a very souped-up transformer. When we change the number of primary turns tapped, to alter the frequency, we do not what to change the coupling as well (coupling is adjusted by changing the height of the secondary). Let’s begin from the most complicated part – secondary coil. Let’s briefly consider what would happen if it were a perfect transformer.

Below is a table of formulas on this page. It has 500-1500 turns turn to turn, my is about 1000 turns. The Tesla Coil (L1, L2) together with the spark gap, generates a high output of voltage when coupled together. This coil has the ability to produce output voltages up to several million volts based upon the size of the coil. accurately for their primary or secondary coils..

The Tesla coil provides a high voltage demonstration of a resonant transformer.

The spark gap plays the role of the switch in the primary circuit. There are three important mathematical nuances or foundations upon which the operation of the Tesla Coil is built. We make this fixed connection to the inner turn because one of the parameters of a Tesla coil is the coupling, or distance, between the two coils. The primary is driven with 340 volts, so the secondary will have 340V x 300 = 102kV across it. I had the primary coil tapped at coil number 8, with improving performance as the number of turns increase. I recommend using a flat coil. Calculate Turns. A good primary coil will end up being about as wide as the secondary coil is tall. My tesla coil’s performance was bottlenecked by, of all things, my primary coil! This quick calculator is available for coilers who need to equate the number of turns, radius, height, etc. Once again, I use the … Tesla Coil Working Principle. The primary consists of a small number of loops made from a large conductor. The Tesla coil works on a principle to achieve a condition called resonance. The number of turns on the secondary coil is not directly comparable to the primary:secondary ratio known from normal power transformers. When the primary is tapped out over nine turns or so, the field flux that is generated couples in the entire secondary winding all the way to the top turn on the coil. My primary coil, sadly enough, was a total of only 8 turns. The large Tesla coil shown above is part of a demonstration show called "The Wonders of Physics" by physics professor Clint Sprott of the University of Wisconsin. Generally, larger Tesla coil use flat primaries and smaller coil can use cone shape primaries. Mathematical Nuances of the Tesla Coil. That’s a lot!
