Hey, I added a file that I just threw together. It obviously needs to be improved. But I wanted to make a simple analysis of how to properly determine the construction of a Tesla Coil. I've only done the mathematics of the secondary, and I need to add in the skin/proximity effects and as such the AC and DC resistance in the wire. But I want to make a "showing by example" tutorial and post it on a blog... and than I realized that a lot of new people go to this site for guidance. Can I work with one of the moderators to make a sticky with a full tutorial for any new comers so they are not so intimidated of the mathematics or the concepts? The doc is a start of my work...

Thoughts?

I think this could be useful I built my first SGTC through a process of trial and error with almost no math involved :) and it worked fairly well with up to 15 inch streamers untill my mots blew up lol. Something like what your describing could have really helped because I just found all of the calculations too complicated to understand (although that was a while ago and it probably wouldn't be to hard with my current understanding)

Thanks for the input guys :D !!! YEAH! I'll update that wiki! That sounds fantastic. I guess I just remember when I was in highschool and visited this website and I was still so lost...

Twist2b, I know how you feel, especially when I was starting to get on building my first SSTC and didn't know where to go to. This motivated me to write up a webpage detailing how and SSTC works, but also to provide a concrete example where I build a super simple coil and try to explain the design choices and calculations.

Here's my current page at the moment: SSTC Design Guide. I hope to work one on DRSSTCs and normal SGTCs in the near future.

loneoceans!!! Your work is fantastic!
You put a lot of work into this man :) I am glad you joined this forum! :D BTW - I noticed you didn't talk too much on the Gate Driver Transformer and it took me a long time to track this stuff down but:

All about the purpose of GDT

This explains how it will look if you have a crappy transformer
Also there is a wiki that has the maths:

Thanks for the comments. Transistor Tesla Coils of today bring together many technologies and it's difficult for me to write everything in comprehensive detail. Even so, there is still much that I don't know or am not sure about, but I'll definitely be updating it continuously with the goal of bringing some of these concepts to beginners with a hands-on practical approach, as well as provide helpful tips for more experienced coilers.

Thanks for the links for the GDT. The topic of Gate Drive is complex and large enough to probably warrant a special article for it! I haven't gone into serious gate drive with large bricks like the CM600 yet though.
