Overview

Never designed a Tesla coil before? Don't worry! TeslaMap makes Tesla coil design fast and easy.

Simply enter your input values and TeslaMap will calculate the output parameters - that's it!

Using TeslaMap

Enter your input values (NST Input Voltage, MMC Capacitance, etc) and TeslaMap will calculate all the Tesla coil design parameters.

Saving A Design

Select "File" then "Save As..." from the top menu to save your Tesla coil design. Once a design has been opened or saved you can re-save the design by selecting "File" then "Save".

Opening A Design

Select "File" then "Open" from the top menu to open an existing Tesla coil design.

New Design

Selecting "File" then "New" from the top menu to clear all the input and calculated Tesla coil parameters.

Export A Design

Selecting "File" then "Export..." from the top menu to save the input and output parameters as a .txt file.

Metric And Standard

Select "Options" then "Standard" or "Metric" from the top menu to change between standard and metric measurements. When switching between metric and standard all the input values will automatically be converted.

Help

The help area will display helpful tips and advice. New help is displayed for each input as you enter the input. Help buttons next to the output parameters explain the meaning of the parameters. The "Primary Help", "Toroid Help" and "MMC Help" tabs display diagrams explaining the input and output parameters.

Registration? Activation?

You do not have to register or activate TeslaMap and it will never contain adware, ad banners, or anything like that.

Program Revision History

TeslaMap ver 1.14.2 Available

June 17, 2010
Updated input validation and error dialogs.

TeslaMap ver 1.14 Available

June 12, 2010
Added support for international location specific number formatting. Thanks Jan for testing.

TeslaMap ver 1.13 Available

May 13, 2010
Corrected the "needed primary coil inductance" calculation. Thanks David for bringing it to my attention.

TeslaMap ver 1.11 Updated

Feb 20, 2010
Added a magnet wire diameter AWG - mm conversion chart and graph.

TeslaMap ver 1.11 Available

Sept 25, 2009
Updated the interface to improve compatibility with Mac OS X. Thank you to William for bringing the issue to my attention and helping to correct the issue.

TeslaMap ver 1.09 Available

Aug 7, 2009
Updated the MMC help screen. Fixed a feature that caused the program to display "Open" in the "Save" dialog box. Added primary coil parameters at tap turn back to the Export file (they were accidentally deleted in the last revision).

TeslaMap ver 1.08 Available

July 15, 2009
I've continued to updated the interface by consolidating several tab panels. All the outputs are now visible on a single tab. I also fixed a small featured that could show a slightly incorrect number of turns required to tune the coil when only odd turns were displayed.

TeslaMap ver 1.07 Available

May 12, 2009
I updated the interface by consolidating several tab panels. Hopefully it's a bit easier to use now.

TeslaMap ver 1.06 Available

April 29, 2009
I managed to get the primary coil inductance calculation with the incline angle working. I sacrificed quite a few brain cells fighting with it.

TeslaMap ver 1.05 Available

April 8, 2009
I added options for flat or vertical primary coil. The conical angle input is still disabled. I updated the interface a bit.

TeslaMap ver 1.03 Available

Feb 27, 2009
I added an Export feature so the Tesla coil design can be exported to a .txt file. The exported file contains most of the input and calculated output parameters.

About TeslaMap

TeslaMap is not...
TeslaMap is not a Tesla coil simulation or modeling program. The calculated results are not intended to be accurate to several decimal places. TeslaMap does not account for ground planes, walls, temperature or other factors that needlessly complicate the program and do not significantly affect the Tesla coil operating parameters.

NST VA = NST Output Current * NST Output Voltage

NST Impedance = NST Output Voltage / NST Output Current

NST Watts = ((0.6 / NST VA ^0.5) + 1) * NST VA

PFC Capacitance = (NST VA / (2 * pi * NST Input Frequency * (NST Input Voltage ^2))) * 1000000

Secondary Coil Turns = (1 / (Magnet Wire Diameter + 0.000001)) * Secondary Wire Winding Height * 0.97

Secondary Capacitance = (0.29 * Secondary Wire Winding Height) +(0.41 * (Secondary Form Diameter / 2)) +(1.94 * sqrt(((Secondary Form Diameter / 2) ^3) / Secondary Wire Winding Height))

For large or small toroids, Ring Diameter < 3" or Ring Diameter > 20"
Use the average of three toroid capacitance calculations.
