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

To avoid thermal run away of the switches, i decided to reduce the number of discharges per second. I added a relay in front of the applied voltage and switched it using a L298N motor driver and an Arduino Nano.
Using this approach I can now increase the input voltage to 170 Vrms without breaking the switches. Discharges up to 40 cm in length can be achieved with such arrangement and input voltage.
PS: Even though in this case I used an IGBT but I still named the video single Mosfet..., to have all of these videos under one name.

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!

@RAVI171175 2 года назад

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.

Thank you

@RAVI171175 2 года назад

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 2 года назад

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.

@Magneticitist 2 года назад

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

@HVE 2 года назад

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 2 года назад

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

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.

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

@hansgustaf3258 7 месяцев назад

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!

@DolezalPetr Год назад

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.

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

@RAVI171175 2 года назад

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 2 года назад

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).

@TiagoSilveiraB 2 года назад

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 2 года назад

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

@@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.

@molty3614 Год назад

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 Год назад

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

@molty3614 Год назад

@@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 Год назад

@@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.
