Solid State Tesla Coil (SSTC) - Part 4

[@quantumlab9130]

This series of videos helped me more than me entire online adventure into the work of sstcs. I’m gonna order some parts and build one. Next step is QCW SSTC.

[@HyperspacePirate]

Glad to hear that. I also plan to build a QCW eventually. Seems like it can be done by feeding an existing SSTC's input voltage with a large class-D amplifier generating sawtooth pulses

[@quantumlab9130]

From my research on QCW SSTCs I would agree that you should just be able to go send a ramp signal through a class D amplifier. I’m gonna order some parts, first build a classic DRSSTC and then move on to a QCW SSTC.

2:24 Thank you for putting numbers to the images! I can easily imagine that helping somebody e.g. diagnosing problems with their tesla coil or something, and just seems like a neat thing to be able to identify.

[@NormReitzel]

Very explanatory. My first Teslacoil used a 6146 bean power tetrode in a Hartley oscillator ( Vac tube Slayer circuit). I was proud of it because mt thing was all done from first principles. I was 16 y.o. at the time. (I'm 71 y.o. now).

[@CuriousChan]

It's my first time seeing someone use an Arduino to feed the notes to a Tesla coil😅 Very awesome, keep up the progress👍

[@HyperspacePirate]

Thanks. If you want to do this, i highly recommend keeping the arduino a good distance from the coil, and sending the signal to the drive circuitry via optical cable, because the E-field of the coil will demolish CMOS integrated circuits

[@CuriousChan]

@@HyperspacePirate thanks for the advice, will keep that in mind👍

[@tarikelaissaoui5467]

All parts are very well explained. Thank you for sharing all informations about this great projet.

[@RAVI171175]

Dude, that's great as you've done an awesome & amazing video. Thanks for sharing & keep it up.

[@ivanrodionov9724]

I found your channel yesterday, really some great content you got! You should try using the output of a class d amp based on a tl494 or two 555 timer chips like I did to interrupt your circuit. You can then also adjust the duty cycle through a potentiometer but with the advantage of being able to add some audio modulation. You could also use some DSP equalization software to compensate for the distortion and get some seriously good sound quality. Alternatively, you could use a pickup with a low pass filter for your audio feedback and compensate for distortion in circuit.

[@grenouille-de-geek]

good job ! you'v made a plasmatronic !

[@kdkinen]

How incredible man

[@thebread8918]

amazing video, btw the 2 outputs are connected on the same place(to the 2n3906 1:15 ) because the signal is alternating(? and Arduino's pwm must to be between the lm317(left) and 3 ne555 interrupters?

[@Yutaro-Yoshii]

The square wave sound reminds me of Temple OS. Every temple OS installation should accompany tesla coil audio system!

[@Phycoty]

Agreed

[@ScienceLab760]

Great video thanks for share, maybe a future project we can see a DRSSTC :D

[@Teslaundmehr]

Heyy, woow i love it! Keep going man! But I dont understand one thing. Why did you use a 3uF capacitor in series to the primary?? Because the primary and the 3uF capacitor are in this combination a LC circuit. The LC is externally excited and you dont use primary feedback, but when this LC is not tuned to Fres of secondary it can cause many problems. I would try to remove the capacitor or to tune the Circuit to Fres of secondary. I cant imagine that 3uF and 2 Turns resonate between 100 and 300 Khz ;) Best Regards!!!

[@Magneticitist]

DC blocking =)

[@HyperspacePirate]

Yeah, just DC blocking. I'm not trying to make the primary resonate and create a DRSSTC. My current MOSFETs and power supply can't provide the necessary current for a DRSSTC with this setup

[@CuriousChan]

Wow, Tesla coil enthusiasts are gathering here, very nice😄

[@Magneticitist]

@@tvishmaychoudhary69 The impedance of a capacitor that size at the average SSTC frequencies is very small, like it's not even there until a DC pulse tries to pass then it blocks it. At 5khz the impedance becomes higher like 10ohms but either way a cap that size isn't going to resonate with that kind of primary.

[@Magneticitist]

@Joseph Bunn You see them on some SSTC's and not on others. For example Loneoceans SSTC 2 uses I think a 4.7uF in series with the primary which basically acts as a DC blocking and filter for the doubler caps on the board. Ward's SSTC 5 just puts some caps across the bridge. I suppose in practice it may be a better idea to put it in series with the primary like that just in case something goes wrong.

[@alexlindgren858]

i noticed in your circuit diagram that the top left and bottom right mosfets are not hooked up the same "polarity" to the GDT, is that a typo or is that intended? (by that i mean the a - b from the GDT)

[@zyzzyva303]

Eruption. Nice!

[@elettronicaemotori]

very very nice😃

[@toygartumer7385]

awesome video

[@petername2608]

Cool will send it to print the board. Can you post your circuit diagram in pdf in some sharing site. So people can download it 👍

[@nathanbunten4299]

Do you have a pcb board that we could order for this project? Maybe on with all the components? If so where do I order it? I watched this series and the battery pack one. They are so much better than everyone else's. If No pcb can you update this project with a list of parts needed? thanks......

[@motosk8er2]

Just discovered your channel and I'm absolutely loving it! Keep up the great work!!

[@proffessornukem8775]

I had an idea for the interrupter I wanted to run by you, what if you used a IC with NAND gates, something like a 74hc00 in order to interrupt the signal going to the mosfet drivers. This in my understanding will shut off both the drivers instead of leaving one driver active.

[@SparkelectricCt]

Did you use a SD card module on Arduino nano

[@RAVI171175]

Check Vai Hinduan as he has also made use of arduino to modulate the output of his Tesla coil by playing note too.

[@alexlindgren858]

quick question, how much current does the gate drive transformer draw? I dont have the TC4422 only the TC4426 which can give up to 1.5 A instead of 9 A. Can i use that chip instead?

[@HyperspacePirate]

I think that will work. It's been a while, but i think the GDT peaks out a little under 1A depending on the drive frequency of the coil. Wouldn't hurt to stick a heat sink or fan over those IC's though

[@alexlindgren858]

@@HyperspacePirate I noticed that the TC4426 has 2 inputs and 2 outputs, can i hook up the inputs and outputs in pararell so that it can withstand more current?

[@aryananiknam4817]

What happened to your 120v sstc? Im planning on making one. im intressted to see your experience and what happend to your old circuit. thanks

[@HyperspacePirate]

It still works, but at 120V it gets hot after a minute or two so i usually run it around 30V

[@AnalogDude_]

That's like these hi end tweeters.

[@Totumfacky]

Ouch! That must have been painful! 10:55

[@toygartumer7385]

I made a sstc by watching your videos and it didn't work. Can you help me figuring out whats wrong?

[@toygartumer7385]

pls

[@HyperspacePirate]

I can try. Email me @ [e-mail] with some pics / more info and ill try to see what the issue is

[@toygartumer7385]

@@HyperspacePirate thank you so much, I will send you photos of it and components I used (probably tomorrow)

[@BBigg-kh7pz]

Do you smell ozone?

[@BBigg-kh7pz]

You could collect the air, pump it into a mixed solution of 2-butyne and water and make some vinegar. That'd be sweet and sour!
