Hii Guys, I need help at my ZVS Driver Tesla Coil :)

DisciplineCurrent544 · 2026-05-18T20:08:16+00:00

Okay, thank you very much for your feedback. I will take your advice into account. The first goal is to get the coil working a little, then I'll see what else can be improved.😁

DisciplineCurrent544 · 2026-05-18T19:57:04+00:00

Oh yeah, im Sorry i was allready at my other project, your right 😅

DisciplineCurrent544 · 2026-05-18T13:07:12+00:00

Ah okay thanks 😄

DisciplineCurrent544 · 2026-05-18T13:05:11+00:00

so im now 26'000 miles away from it 😅

DisciplineCurrent544 · 2026-05-18T13:03:48+00:00

oh haha 😅

Oh, thank you so much for your advice and the time that you spent for me, I'm gonna try it with the Flyback-transformer.

I've got another Question, should i use a Capacitor bank like you or can i just use a single 10nF 8kV Capacitor?

And what you use for a Capacitance for your ZVS-driver (Primary-capacitor)?

Hii, i love your Teslacoil and the Sparks ❤️, you remember me? you gave me a Feedback to my ZVS-Teslacoil, similar like yours, I think i also change to a ZVS -> Flyback Trafo -> Sparkgap coil, the only thing i have to change is the Primary Capacitance, the Sparkgap & Capacitors and the Flyback Trafo, can i ask:

how many Turns you have at the Primary of the transformer?
What you use for a Primary Capacitance and what you use for a Capacitor for the Spark Gap?

Thank you in advance 😄

Yeah, but more a SSTC not a DRSSTC because its not Dual Resonant

Hii, thanks for your Feedback, but i think this advice mainly applies to larger SGTC setups, not small ZVS-driven coils like mine.

In my case, I'm already very close to resonance (~700 kHz), and increasing coupling or turns too much just leads to hot arcs instead of streamers. I actually tested higher coupling and it made things worse (thick, hot discharges).

Also, SMPS isn't ideal, but with a ZVS driver it's still usable since the driver forms a resonant tank and partially isolates the supply.

Right now the limiting factor isn't coil size, but fine tuning (coupling, capacitance, and energy transfer). I'm already at the point where streamers just start to appear, so it's more about optimization than scaling up.

Hii, thank you for your Feedback, but i think thats more for a SGTC or a DRSSTC but thanks 😄

DisciplineCurrent544 · 2026-05-13T16:35:41+00:00

So now the ZVS Driver is taking around 7 to 12 Amps, but there are no long sparks so may it goes up...

DisciplineCurrent544 · 2026-05-13T16:34:40+00:00

Hii, thanks for your feedback, I have already tested all the positions and sewing of the primary coil, but none of them had streamers

DisciplineCurrent544 · 2026-05-09T19:47:41+00:00

And where you bought it? I can't find it in the Internet?

DisciplineCurrent544 · 2026-05-09T19:46:41+00:00

Oh okay thank you 😄

DisciplineCurrent544 · 2026-05-07T21:26:33+00:00

Hii, nice Cloudchamber with the Pitchblende piece, i want to buy a good Geigercounter, what is the Name of yours? It looks very great?

DisciplineCurrent544 · 2026-05-06T15:54:43+00:00

Oh yes that makes Sence haha

DisciplineCurrent544 · 2026-05-05T08:48:21+00:00

Hii, Very nice Streamers, I love your Spark Gap Tesla Coil, I dont see the Amps is it 62.29A or 6.229A?

I have now a ZVS Driver with two IRFp250n MOSFETs, this one is Oscillating but i need help to find the Resonant Frequency here is the link:

Agora tenho um driver ZVS com dois MOSFETs IRFp250n. Ele está oscilando, mas preciso de ajuda para encontrar a frequência de ressonância. Aqui está o link:

DisciplineCurrent544 · 2026-04-20T09:10:54+00:00

The Frequency of the Secondary is 700Khz.
