Secondary Resonant Circuit Size
« on: April 13, 2021, 11:52:24 PM »
I'm trying to build a mini Tesla coil, but I have run into a problem in the design phase. Throughout anywhere I looked I haven't been able to find the proper size for the secondary resonant circuit. I understand that it needs to have the same resonant frequency as the primary resonant circuit but that only has bearing on the ratio between the capacitor and inductor. The only lead so to speak that I have is that the secondary in primary coils work as a transformer but again nothing I've found says to what degree. I have to imagine that there is a point where the secondary coil is too big to work with the rest of the circuit, but I have not been able to figure out what that size is. This seems like a relatively basic question but for the life of me I have not been able to figure it out. So is anyone else knows what I'm missing here that would be greatly appreciated, as this is the last thing I need to finish my design. Thank you.

It is aimed at classic spark-gap coils, but is great information for solid-state versions too.  Start with their built-in demo coil.  Do be careful of units (cm or inches selectable) and radius vs diameter (some parameters are diameters and others are radii - all listed, but pay attention).

I tried to cover a lot of these topics, about how to size things to a given power, budget or expected spark length. I wrote a very large DRSSTC design guide, that for most parts are principles that work for all types of Tesla coils.

For the secondary coil size, I also made a data table with many different design choices to different wire gauges, forms and ratios, lots to choose from in the tesla coil secondary design guide :)
