lool this is a great video of perseverance. That little prayer before testing was hilarious. I never had the patience to try tweaking one of these but your end result was one of the best I've seen.
In regards to the MOSFETs that kept failing, I think one of the issues is that you aren't using an RC snubber (resistor and capacitor in series) in parallel with the source and drain of your mosfet. When I was building a half-bridge flyback driver, my mosfets kept dying every time I increased the voltage. So I watched a video by DiodeGoneWild in his SSTC playlist, and his RC snubber fixed my problem once and for all. I understand that you had to make a lot of adjustments to your circuit and resistors to make the problem go away, but some of the things you did may have reduced the performance of your Tesla coil (increasing gate resistance). With the RC snubber, your MOSFETS will be able to handle more power and thereby increase the output voltage of your Tesla coil.
@@styrishrodrigues I don't think anyone can help you with the extremely limited info you're providing. Post a schematic and picture of the setup to the electrical engineering stack exchange forum or reddit or something and I'm sure someone might help you.
Hello George I hope you are doing well and fine. I just want to ask one doubt in your respective schematic. 1) Can u tell my why R6 is 200 watt, i am not able to find one, can u suggest me any solution for this? 2) what can find 250 watt mercury ballast with 2.1 ohm resistance? Iam inspired from your project, i myself made many Tesla coils but your version of circuit is most efficient one i have ever seen. Thanku once again, please clear my doubts and its nearly going to complete my tesla coil.
You will solve this problem as I solved it with two resistors see: ruclips.net/video/MG-pD43i_6A/видео.html about the ballast you I'll have to find out and I can't help you with that, sorry.
@@eleman-gc thanks no problem at all, I will try more, untill now I have tried nearly 20 attempts, I will keep going, untill I get success. Those resistors u used are of 100watt Or 50 watt, in parallel? Thanks I referred your video again.
Awesome project. Your setup is very easy and effective but not so safe (half or full bridge SSTCs at least provide isolation between the primary and the secondary). The only thing that I don't uderstand is why you used cardboard instead of PVC.
Hey George! I'm trying to make a very similar circuit to run off of 330V (from 120V through a doubler), do you have any suggestions? Has this circuit died on you yet?
This circuit is for AC and not for DC. If you want to make the same circuit use the main power 120v and find 250w ballast on 120v into your country and changed the resistances to the gate. I think you will play between 8k or 10k or 12k on the resistor "R3". Another important resistance is the "R6", but I'm not know the coil you have made. maybe you have play between 20ohm or 50ohm or 70ohm, I do not know I'm not sure. Whatever you do, be careful and follow the safety rules.
Yeah even I have used the same circuit with changed gate resistors .. there I one catch though ... Lower frequency secondaries work better ..mine is arround 150khz
Hello ! What could happen if I do not connect the ballast? I would like to make it portable with a 220VAC inverter with no ballast, because of the heavy weight Thanks a lot from Spain 🙏🏻
Thanks for your video! My question is where did you get the BALLAST from? I have couple ballasts but none have the measurement of yours. Where in the USA can I get a ballast like yours? Do you know of the brand and part number? I would like to make this Tesla Coil, but the ballast is my stumbling block.
If you put your coil next to alot of metal objects. Tools, drill press,.... adding a topload will cause interactions that are no good. I figured this out when experimenting. Every time i added a topload the coil failed. Then it struck me. It was 20 cm away from my drill press. I moved it away and from then on i was set.

Everything works just fine until I start playing with the arcs. Every time I do that the mosfet stops working (shortage between all leads). Is this caused by some sparking or overvoltage when I play with arcs?
I tried using the thyristor circuit, but instead of a single diod rectifier i used a full bridge and it didnt start working at all.. anybody knows why? Thank you
@@JoshHopkinsYTyes no doubt mosfets work however I was under the impression that the spark gap generator's adjustability was key to the whole experiment combining electricity with resonance. Having the set values of what ever mosfets are available might be missing the whole point there would be no adjustment for resonant frequency .. We now have capacitors that incorporate a plasma arc within them so what if that could be taken in a more advanced direction along with spark gap technology taken to the next level, Tesla understood the ether and to be able to work with the ether would be why Tesla created the Tesla coil ....
Don't build theese cursed slayer exciters. Half bridge is much better. Steve ward's SSTC 5 is simple and you can get 30cm sparks with it plus the mosfets don't blow up randomly
Sorry if you found that offensive. Well secondary isn't isolated from mains and from my experience mosfets blow up quite often. Idk maybe I just tuned it wrong
@@martinbobak3009 No problem bro! Steve swarts is very difficult circuit, this is so simple but very danceruse. Mine also works very well and is very bowerful.
I would like to build such a Tesla coil as you did, but I would like to first understand what every component does before building one. I struggle with the usage of the ballast. Could you please explain to me what its purpose is? You said ballast should have small resistance, but another guy who built very similar one (basically the same coil but on 120V) used a light bulb as a ballast which has high resistance. the guy: ruclips.net/video/Q0lkg9lxz3s/видео.html

Yes , indeed that very true .
I love you all crazy men!!!. How crazy you must be to construct Mr Nikola Tesla Coil. Mr Nicola Tesla is my favorite and the best scientist ever
Your satisfaction is the most important part of your work. You did great and I appreciate. Thank you
well congratulations for finally succeeding. you worked very hard thru all the blown up Transistors and other parts. Good to see your success!
Very nice video! Simple and clean construction, easy to follow schematic. Spark output is very impressive! Keep up the good job!

Hi there.. Even my tesla coil has capacitor and resistors in series with igbt.. But my tesla coil isn't working.. Please help
@@styrishrodrigues Have you tried adjusting the number of turns on your primary?
@@vusiliyK yes.. My problem is it isn't creating resonant frequency.. Everything is fine

Nice video, you should have used danyk SSTC driver is simple in one way or another
Vous'ette un génie magnifique ces la meilleur tesla que j'aimais vues
Also, how would this circuit work under USA 120V? What exact original TC schema did you modify? Thank you.
Incredible, i will try this schema ! Thx u for all 😌
I have just made a Tesla with TIP31c transistor. It’s Time to craft a big tesla ⚡️

Hiii friend, just a small doubt, did u short the pin 2 and 3 together of the potentiometer? Please it really urgent.
good work!! ... can you also use an IGBT transistor?
No for this circuit because you have to make changes... www.differencebetween.net/technology/difference-between-igbt-and-mosfet/
@@eleman-gc you're right .. the IGBT transistor is used in half bridge circuits for DRSSTC

Mercury Transformer 250W Ballast
For mercury lambs
Can i use D2 without this interrupter? How this voltage doubler exacly works? C1 is necessery for D2 to working?
Can we use a UPS transformer instead of a using ballast

It works with 220v instead of 240v?

Is it mandatory to use ballast?
yes
whats the purpose of d2 in the circuit?
Hi! I'm very glad to see you!!!
ЛАЙК!!!
How many turns on the cardboard
I like it😊
nice one
can anyone explain to me the purpose of d2 in this circuit?
Doubles the voltage at its input of ballast.
Hi try using a half bridge great video
A-m-a-z-i-n-g 😊
Everything works just fine until I start playing with the arcs. Every time I do that the mosfet stops working (shortage between all leads). Is this caused by some sparking or overvoltage when I play with arcs?
top load is necessary...
@@eleman-gc I used some moderately large topload, but the same thing happened. Do I have to try even bigger one?
I tried using the thyristor circuit, but instead of a single diod rectifier i used a full bridge and it didnt start working at all.. anybody knows why? Thank you
Amazing
No mosfets at Tesla's time, He simply used spark gap with capacitors...
He would have used transistors too if they were around
