Single Mosfet Solid State Tesla Coil ( SSTC ), no gate driver , ~ 40 cm streamer length

[@RAVI171175]

My God! Amazing video & awesome work too. No complicated electronic circuitry nor tons of electronic components used. Just simplicity. My greetings & respect for your work as that's the best ever simplest setup I've ever seen so far. Keep it up.

[@HVE]

Thank you

[@austindale3129]

That amazing how you have achieved the staccato arcs with a single IGBT, I have only seen outputs like that with QCW's and vaccum tubes. Really Great work! Just when I thought I've seen it all, You Rock!

[@CoolDudeClem]

Could you do a video explaining how to calculate the values for the snubber? I am doing my own Tesla coil experiments and have already killed several mosfets because of high voltage spikes across them.

[@Magneticitist]

Looks good. It would seem to give nice ramped swords with the proper voltage waveform. Staccato interrupter would seem to work well.

[@HVE]

Yes, the voltage waveform, the voltage magnitude, the switch type, the coils arrangement etc. all have impact. Getting the right voltage waveform has a considerable impact on the output.

[@Magneticitist]

@@HVE lol yes, a long list of sometimes frustrating variables come with these things.

[@RAVI171175]

Many out there are doing PLL, QCW, half bridge, full bridge, etc , just to have those kinds of output! My friend, you have demonstrated all in one as a package! that's indeed awesome. I think next thing on your list concerning the same coil, is to make it play music through a midi system. I mean make that single IGBT play music. There's already one guy from indonesia who has already tried it with his single mosfet & his channel is Tesla Musik Petir. I think that among all that I've seen out there, your built is the minimalist one with awesome outputs. That's the spirit & just keep it up. Thanks

[@HVE]

Thank you very much for the comment, will make the musical one in the future. Also I have plan to make the discharges longer. Now is a busy period of the year, as soon as i get time, an improved version will be shown.

[@For_the-love_of_physics]

I was able to make that Tesla coil because you helped me. Now it's working🙂🙂🙂 (MOSFET - IRFP460).

[@HVE]

Congratulations, usually first time getting it to work is a bit difficult, thereafter things get easy

[@midnightengineers26]

@For_the-love_of_physics do you got the TVS diode? Can I use any alternative diode

[@elynaindahbudiasih3279]

it looks the arc like a quasi continuous wave dual resonant solid state tesla coil

[@imeprezime1285]

40 kV at 400 kHz for 40 cm sparks 🙂. You can measure voltage by attaching small sphere gap at the top of the coil (while taking care of frequency shift)

[@hansgustaf3258]

Your circuit is awesome. Really beautiful and awesome. The H bridge doesn't necessarily have to be controlled with an Arduino, right? Would a PWM signal generator also work? Great project! Thanks!

[@CoolDudeClem]

Is the "adjustable voltage regulator" (connected between the variac and the sstc circuit) is that actually just a dimmer switch?

[@HVE]

Yes

[@Sparkjoylearn]

how can i modify this circuit to run at 230v? Will increasing the gate resistance from 100k to 220k ? pleasr i need help

[@electrogravlabs]

HOW ARE YOU GETTING THOSE SWORD SPARKS????

[@parodox1015]

Could I feed audio into the H bridge and use a MOSFET to control audio?

[@FlammableElectronics]

Hey my FET is hot in few seconds and I can't see arcs out of secondary, using 12v 15a

[@davestewart2433]

Well done sir. I have spent a month and $100'S on a complicated QCW DRSSTC and your setup produces bigger breakout lol. Well dang it. Time to whip up one of your builds and see. Thanks much. Can you post the arduino sketch code please, thanks.

[@electrogravlabs]

Are you using any type of ballast? I ask because I'm building this circuit

[@gerritdeniet6243]

Incredible results! Thank for your clear demonstration. Question; won't it be advantageous to replace the relais by a interrupted mosfet?

[@HVE]

Thanks, yes, it is possible and I will do it in a future video. Now I am working on this circuitry to make longer Arcs. Will summarize the new results in a video.

[@AgnivaMaity]

Hi! Very nice coil, can you make a video on how to use this with 555 timer interruptor Please? My request.

[@devilvortex1]

can I use a scr instead using an mosfet?

[@DolezalPetr]

Hello, how tall is your secondary coil without topload and what is the diameter and how tall is your topload? My guess from the video is that the secondary coil is maybe 15cm tall and the topload adds another 8cm or so, but I am not 100% sure.

[@OngVoELstuffs08]

That was so fire! But I still don’t know why many people think that sstc with single mosfet drivers are suck?

[@boerkuhjah]

Mm this is very interesting, I like what you do. 👌

[@RAVI171175]

Sir, concerning your snubber, you forgot to tell me where is it exactly connected! I just got my K40H1203 IGBT. Grateful if you can precise that little connection for me. Thanks

[@HVE]

Snubber is placed between D and S

[@RAVI171175]

@@HVE Thanks.

[@TiagoSilveiraB]

Incredible result! I will definitely build this project. A question, what is the specification of the relay used? Have you considered using a solid state relay?

[@HVE]

it is just a 12 volt dc 30/40 amps relay. Solid state switch i will implement it later, you must be careful with its design, it can easily break if not designed properly

[@TiagoSilveiraB]

@@HVE I think you misunderstood, I'm not referring to Mosfets or IGBTs, but to a component similar to this: SSR-240D25

[@HVE]

@@TiagoSilveiraB Hi, Okay I see. Yes, this will most likely work, but since it is expensive I would use it cautiously.

[@RAVI171175]

By the look, it looks same as an automotive relay. I've got same & used them too they worked perfectly fine.

[@Doctorlockpick]

What relay are you using? In your schematic the ground is connected to the bottom of your secondary wire, what is that same ground connected to?

[@HVE]

Relay is a low voltage 12 V dc 30 A automotive relay. Ground is floated in my case.

[@Doctorlockpick]

Cool thanks

[@AbuAsyifa]

wow amazing streamer lenght. would you show me pvc's diameter for your secondary coil?? is it a 2.5" pvc pipe?

[@HVE]

I think it was around 75 mm diameter and 170 mm height. It is just a salt container made of cardboard which i put some wire around it. take a PVC pipe with 80 mm diameter, it should work as good.

[@AbuAsyifa]

@@HVEthanks for your explanation. actually i've build a copy as seen on your video. but i wind 0,15mm wire to 60mm diameter and 130mm height pvc pipe. not bad.. i got about 25cm streamer. next i'll try to replica your project. would you show me your wire size?

[@HVE]

@@AbuAsyifa That is given at the beginning of the video, on the schematic. 0.2 mm

[@AbuAsyifa]

@@HVE oke thanks alot brother, i've missed that point

[@Doctorlockpick]

Did you say single diode or signal diode? What variable power supply are you using?

[@HVE]

Single diode. It is a variac, 230 in, and i can control the output voltage by rotating its knob.

[@Doctorlockpick]

Thanks!

[@liladude13]

Very well explained video 👌

[@HVE]

Thanks Hassan, it's not your turn to explain very well the calculation of winding capacitance 😎

[@RAVI171175]

@@HVE Thus, if the diameter of secondary coil is 110 mm & with around 750 turns, your Resonant frequency is around 380 KHz. By further adding a big topload, your resonant frequency has now become around 250 - 300 KHz . Most of the single mosfet slayer exciter circuit works around the same resonant frequency but yours is by far the best I've ever seen.

[@HVE]

@@RAVI171175 Diameter of the former is 71 mm in this case, and the resonance frequency is 420 kHz.

[@RAVI171175]

@@HVE But if you've used 71 mm former diameter with 0.2 mm magnet wire with a winding length of 150 mm ( you mentioned 750 turns), then with JavaTC or any online calculator, your resonance frequency will be around 670 KHz.

[@HVE]

@@RAVI171175 420 kHz is together with the top load, and last time when I measured it (420 kHz, shown in the previous video) there was a metallic plate under it which also impact the total resonance frequency (lowered it than ideal case)

[@molty3614]

hello, i have a question, can i drive this circuit with the voltage regulator straight from the outlet 230VAC? im using irfp460. and do you regulate the arc lenght by the variac or the voltage regulator?

[@HVE]

I think if you don't have a diode, you will apply negative voltage across your MOSFET and that will burn it.

[@molty3614]

@@HVE i would use a diode i was thinking if i have to use a variac because i dont have one so if i can plug the voltage regulator straight to the outlet and regulate the voltage with that (with diode in series)

[@HVE]

@@molty3614 Hi, You can do that, but probably you can not turn the knob of the regulator too much, otherwise your MOSFET will burn. Start from the minimum level and very slightly turn the knob, until you burn the first mosfet, keep the knob 20% less than that value for any future test. Above ~ 150 V it is likely to burn the MOSFET, with the current parameters. You can change the design parameters and you can directly use 220 V.

[@molty3614]

@@HVE thank you for your information. Would it be possible when you have time to reply to this comment with the changes i would need to make with the circuit to make it run on220VAC? You dont have to. Thank you for your time.🙂

[@molty3614]

@@HVE hello i wanted to ask one more question can i make the resistance of the potentiometer higher than 50kohm to something like 100kohm to make it run on higher voltage?

[@RAVI171175]

Dear Sir, I just wanted to ask you about that blue ceramic capacitor & the other component found on that connector on your power Mosfet transistor. Is that high voltage ceramic capacitor, what's its value & the other component, is that a resistance? If you don't mind dear sir, is that your snubber circuit? How did you connect them on the transistor? Are they connected between the drain & source? If so, what's the value of the blue ceramic capacitor plus its voltage rating and the resistance ?Concerning your arduino nano, did you program it? Awaiting a prompt reply from you dear sir as I highly appreciate & admire your video. Thank you in advanced.

[@HVE]

It is a simple snubber, you can use a capacitor that is 3 kV or more, the resistor must handle the power loss in the snubber, since i did not have a good resistor, i used several resistors in parallel to increase the total power rating of that resistor. The values were mentioned in the video. Arduino nano is programmed very simply by turning a pin on have a delay and turning it off have another delay, turn on delay better to keep it around 11 ms, turn off delay anything above 200-300 ms is okay. you can reduce it as you wish but must be careful that you don't burn your switches. I selected 307 and a delay of 11 ms to have some randomness in the discharge (it sweeps over time over the 50 Hz).

[@youngk2495]

Your circuit diagram does not have 1nf capacitance

[@Headbutter-Lettuce90]

Why don't you try a PLL SSTC with a half bridge of MOSFETs

[@HVE]

I am playing around with this simple circuitry to find out its limitations. The plan is to investigate different topology, gain some in depth knowledge and summarize all finding, together with detail theoretical analysis in 2 articles. So the other designs will also be explored in the future.

[@googleuser2544]

Can I use irfp150

[@HVE]

It probably will burn, that mosfet has only 100 V DS voltage. Unless you apply very low voltage on the input, but then you will not get large discharges. Anyway give it a try and let us know.

[@googleuser2544]

Sure i will let you know

[@googleuser2544]

So like can i use 9v 2amp or 12v 3ap
