Make your own Tesla Coil (Part 2) || SSTC, IGBT Full Bridge, Interrupter

[@greatscottlab]

Here is a quick explanation for those who are losing their mind right now because this will be a 3 part project instead of a 2 part project. First off, was it planned as a 3 part project? No! I usually try to stay away from such long projects since I know that not every viewer will like the project. And spending 3 parts on it or 3 weeks will certainly annoy such viewers who have no interest in the subject. But I had no other choice to extend it to a 3 part project this time. Not only was the build process very long but also problematic. I am still currently working on the feedback part of the circuit. Also I wanted to include how to play music with such a tesla coil since many viewers asked for it. In a nutshell such 10 minute videos are the absolute maximum that I can produce in one week in this one man production style. The first two parts were full so I had to extend it. I am also not sure whether part 3 will follow next week, since I want to offer variety for the viewers. Anyway, I hope you understand my struggle and look forward to the conclusion of this project. Stay creative!

GreatScott! We appreciate good things and understand that good things takes time......You have taught me a lot about electronics to me..... Thank You...

[@josech5743]

GreatScott! keep the great work man!!

[@RobEinstein]

If it had 50 parts I would watch all of them with a big smile in my face... I can't understand those people who are complaining about a free content (amazing content I should say)... It is understandable that people want to see more and more from GreatScott... but... come on, some people are playing really low ("he splits the videos because he wants more money...", and bla bla bla). GreatScott, for me your channel is one of the best channels about electronics on youtube and far my favorite. Keep up the great work and try to ignore those negatives comments. Greetings from the neighbor Switzerland!

[@faizanshakil6453]

GreatScott! I don't get it. when your are using arduino then why are you using 555timer for PMV signal. you could have just program arduino for that . if any one gets that why is he using 555 please let me know.

[@filipbitzan5208]

it's PWM

[@SharkyMoto]

good that you used a FULL BRIDGE RECTIFIER

[@NicolasBana]

ElectroBOOM approves this channel

[@patchoulino]

H bridge* your welcome. He only mentions that it could be possible to use rectified mains voltage but never implemented the FULL BRIDGE RECTIFIER

[@SharkyMoto]

u liar

[@TeslaNick2]

Patchoulino is correct, the driver is an H-bridge, not a bridge rectifier.

[@captaincrazy5008]

Every time I see a FULL BRIDGE RECTIFIER comment I have to click like...

[@RYU47376]

FULL BRIDGE RECTIFIER!!!,... wait wrong channel

[@PimDoos]

RYU47376 I was thinking the same thing

[@yiyou6529]

RYU47376 it will be fun if he does the same thing with his German accent!

[@szoszaty]

Sorry, but I don't get it. What is funny about it? Thx.

[@nicestmanintheworld]

+Szoszaty ElectroBOOM

[@alias6676]

It's not single diode rectifier. It's FULL BRIDGE RECTIFIER!

[@LilDefuseKit]

I love how neat your circuit skematics are.

[@PimDoos]

You and ElectroBOOM should collaborate sometime

[@henrikhenkel1337]

That would be really nice... Funny and informative at the same time :D

[@saadshabir7977]

PimDoos I tried building a Tesla coil using his circuit design didn't work so I'm just using fly back transformers.

[@MrFlashgrenade]

Accent overload

[@keltonbailey]

I love flybacks

[@RizLazey]

PimDoos no, he should colab with eevblog

[@alloverflorida5886]

Never seen a lefty with such immaculate handwriting skills! nice work

[@jamayetuddinahmed3713]

So far you are the best bug finder of electronic and electrical circuit I have ever seen.

[@siriuss3894]

Who else doesnt understand shit what he talks but watches anyway because it's cool?? i cant be the only one...

[@MD-vs9ff]

Sohoraye Yaadhuv Not me. I've got the understanding part.

[@ahmetasantas7099]

Sohoraye Yaadhuv comments like this are everywhere we dont give a damn if you dont understand what he is saying there is a lot of people who does so stop posting comments like this

[@siriuss3894]

Ahmet Asantas bruh youtube has millions of users commenting here wont help...shoo try somewhere else

[@lightguy250]

I don't understand but I watch so I can learn. It's a fun way to try to understand.

[@webchimp]

I used to not understand, but watching this guy, bigclive, and Julian Illett (plus a couple of others) I now understand a lot of the basics.

[@Uros1410996]

Wow, just wow! This should definitely be recognized as art! Such combination of precision, efficiency and pure knowledge is an absolute jaw dropper! Every electronics student and hobyist needs to see this and use it as inspiration! Keep up with amazing work mate, best of luck for the final touch!

[@boukhelkhalyoucef]

Great Scott! I watched every video you made , until now , you are my favorite youtuber/teacher keep it going I really like your art

[@greatscottlab]

Thank you very much

[@jneirag98]

I wish I could have all the tools and electronics required for this awesome project. Excellent video!

[@CaptainSaus]

As an electrical engineering student, this makes me really happy :P Love your channel!

[@greatscottlab]

Thanks

[@AshutoshSingh-to9vx]

have you graduated now ?

[@Ev-wj3lm]

Update, update !

[@ThatGUY-ml4kx]

man that is allot! I doubt anyone would build it because of the intense items and smarts you need to build it, But I find it very entertaining to watch someone build it :D

[@michealkinney6205]

The idea to use ducting was awesome. Fun video and project man. Kudos on the video. Thanks

[@th3hunt3r85]

You have all of the support from all of your trusty viewers so keep the great work and Stay Creative ;)

[@mihaidaian9629]

you are doing such a great job with that project . i think that you and electroboom have the best videos with tesla coil.

[@melonswag420]

Zentimeter

[@nrdesign1991]

Serious

[@yasyasmarangoz3577]

What do you mean?

[@Marwan_og]

Germans have a hard time pronouncing the letters "ce" together without turning it into "ts" That's why centimeter is actually Zentimeter in German That's why there are words like Zertifikat (certificate) and Tendenz (tendency), frequenz (frequency), and Arroganz (arrogance)

[@user-ed7gm7ol8k]

how can you work that clean? 6:46

[@anonym7500]

That´s exactly what I thought when I tried replicating one of his projects, he makes it look very easy...

[@moth.monster]

That topload thing really does give it that Tesla coil look. I love it.

[@kahe7436]

I made it a bit small but with slayer exciter with power transistor at 12volts and got even bigger arcs than your previos version. Thanks for your help 😀

[@lukofezz]

Hello, Scott, greetings from Litauen! I already built my SSTC using two IR2110 ics and IRFP460N mosfets. Noticable heating starts around 80VDC on the full bridge. High and low signals are generated using STM32F4 discovery board, TIM1, which has complemetary outputs and adjustable dead band. High and low side signals connected to driver IC's through optocouplers and current buffers. Discovery board is supplied with isolated 5V 0,7A supply and drivers are supplied through 7812 and 7805 regulators for each IC. Mains are regulated via variac and then rectified. Sec coil is around 40cm height and has approx 1100 turns and primary uses 10 turns. With 100VDC ( I was happy wth that for around 5 seconds and one MOSFET blew up :D ) I got around 15 cm discharges. Really nice channel and videos ! Good luck with a Tesla coil!

[@greatscottlab]

Thanks for the feedback :-)

[@NerdlabsSci]

as an experienced tesla coiler i have to say that you actually made a really good SSTC

[@greatscottlab]

Thanks😁

[@Modus_Pwnin]

I'm envious of your soldering skills. Practice indeed makes perfect.

[@matthewcapps418]

I love how i watched this whole video as if i had any idea what he was even talking about

[@9551Dev]

lol

[@ArsyadKamili]

You pronounced 'centimeters' the proper way now; awesome.

[@FireSwordl]

Very professional work! You have in depth knowledge, and not afraid of complex circuits :) Good job!

[@Raion26]

I only understand like 20% of what is said but it is still very interesting! Keep up the good work.

[@alexanderadelmann766]

I deeply envy this level of technical skill

[@JoshuaRando]

The Steve Ward Mini SSTC schematic is super reliable, powerful, efficient, and easy to build. I built a 10 in tesla coil using this circuit and get 10 in breakout. The mosfets I use did not even get warm even at 100% duty cycle which is crazy.

[@gauravjoshi747]

this project requires so much patience , waiting for part 3

[@barbasbandas6665]

I can understand all the work behing your videos. You are doing a great job, as usual. Release the final chapter or the next chapter when you feel its time for it. not because people are crying bla bla bla.... Its your channel, do it your way, we viewers are here to support you. Keep the solid work, you inspired me (17yo teenager) to study electronics in university. Have a good Sunday Great Scott

[@greatscottlab]

Thanks for the feedback. Good luck with your studies.

[@barbasbandas6665]

Thank you : D

[@Brutaltronics]

I love it when Full Bridge inverters don't explode as soon as you connect the power supply

[@bansheedearg]

You had an Arduino. You used a 555 timer. A second Arduino would have been more than enough and given its sheer power. Yet you used the venerable 555. Huge respect.

[@derwissenskiosk8041]

So much power for such a small arc.... OMG.... : (

[@robindegans9014]

It's the voltage that makes it jump across air, not the power.

[@derwissenskiosk8041]

I talked about the input not the output power , and what you say is right but that ist what happend here and it is wrong... A tesla coil have put out the highest voltage that it can and not current / His tesla coil is efficiently but it is more like a flyback transformer

[@patchoulino]

it was not that much, he is using a bench power supply.... maybe if he used a FULL BRIDGE RECTIFIER

[@clementdel2776]

oh ... i check your channel and you have more powerfull stuff :3

[@robindegans9014]

I'm sorry, I did not realise what you actually meant by power, some people think voltage and power is the same so I wanted to correct that. have a good night!

[@crolex6443]

these videos are somehow satisfying

[@shubhamgiri5801]

I always watch whole add in your video to support you

[@BritishBeachcomber]

I love the NE555 timer chip. Been using it since it was invented by the Signetics Corporation in 1971.

[@TombVali]

I'm glad that he used a FULL BRIDGE RECTIFIER

[@Robol]

i dont understand anything about this video, but its just nice to watch for some reason

[@twilliragger3928]

Your Videos are so awesome :D I always like to watch them when I go to bed

[@waqaszahid86]

looks promising, will be looking forward to the 3rd part

[@arrobamarcos]

Are you planning on making it sing?

[@greatscottlab]

Yes.

[@97Giorgos97]

The Zentimeters are back! 😁

[@jamesandonian7829]

really like what you did with the air ducts

[@markoantesic4362]

@GreatScott! Add a deadtime between the high and low pwm signal this will make the IGBTs run way cooler.

[@2010craggy]

Tesla coils do require some quite extensive setting up to maximise there resonate frequency, which improves miss matches and the overall efficiency of the coil. Solid state drivers for these can take what seems an eternity to design, tweak and reconfigure, but modulating (pulsing) the output driver helps keep the IGBT transistor's cooler. You could also add some sort of thermistor feedback circuit to one of the heatsinks which you could use to provide a thermal value to the Arduino which could be configured to reduce the output voltage as needed to stop thermal runaway- or worse case scenario, shut down and protect the IGBT's.

[@electroimpex8897]

I am Impressed, You are a Genius

[@mrono1910]

I love old Norwegian music :D There was one in this vid :D

[@joshuaamerson2365]

Thats all the stuff I was gonna say. And um, he said ⚡duty⚡. Super good video!

[@TheSwissGabber]

The IGBTs get hot because tdon is smaller then tdoff, 100ns in your case. that leads to cross condition. use a driver like a IR2184 which has a 500ns dead time built in.

[@Xeno_Bardock]

If you add Extra Coil and connect it to the Secondary Coil and then connect Top Load to the Extra Coil like Tesla recommends in patent 1119732, you should be able to get even larger sparks. Extra Coil aka Resonator acts as a magnifier. The Colorado Springs model of Tesla Coil is called Tesla Magnifying Transmitter.

[@HJCF0520]

Wow, that's dedication. Excellent video!

[@meclucas]

Very nice project, congratulations. It would be nice to have the audio from the Tesla coil working, the "Bzzt Bzzt" sound is very interesting, maybe in part 3? Again, thank you for your videos.

[@zs8784]

Hey! I am a huge fan of your work, learning quite a bit. I gotta say though, when you work with larger stranded copper wire, an inline crimped barrel splice and heatshrink would be a much better way to go. Soldering has limitations...

[@FalconerDelta]

looking forward to the last chapter

[@sonicahedgehog9814]

Yes part 2. Keep up the videos.

[@milespeterson5049]

Wow for how big this circuit is it's not very strong. maybe you can replace some components for what work on voltages, and boost the voltage to 50v.

[@lukalopin]

There is no dead time in your driver, that could be the reason of heating. Switching IGBT in open circuit could breakdown the gate. Also, oversized topload ruined Q factor of Tesla coil, so you get smaller discharge length for the same power. Beside that your project looks nice, well done.

[@ronjon7942]

Chuckle, love Peer Gynt, In the Hall of Great Scott.

[@jantsbenzproaudio]

Wow i'm exited for part3

[@sparkyprojects]

Most SSTC's that use a full bridge have a capacitor in series with the primary, that may reduce the current and heating. Also, check that black paint, many use carbon to produce the black colour,

[@spacemini24]

I love so much your videos !

[@mydogismilly]

you can mark center by making a line from opposite corners in an x shape

[@lokeshrahul8504]

those little purple arcs can be easily obtained from flyback transformers used in old tv sets, I thought those arcs will be like deadly green or something

[@brianmwenda1940]

yeeiy... was waiting for this. Thanks man

[@MCsCreations]

Really great work!

[@dreammfyre]

I'm trying to build this, but there's voice telling me "Insufficient power." every time I try.

What

[@oleschnorr3543]

du kannst auch ein stück klebeband über der draht auf der unterseite der platine kleben und dan weiter unisolierten draht verwenden da so kein kurzschluss ensteht

[@Aperson-sv2hc]

I've assembled a tesla coil kit for one of my high school teachers. It uses half-bridge and it sings. Worked a bit, and then started blowing the fuse immediately after plugging it in. I removed the igbt's and they both measured only a few ohms no matter how they were probed. After watching your video, I believe the fault lies in a design flaw. The protection diodes on the igbt's. the kit says they are optional, and does not include them. Right... optional only if you don't care how long it lasts.

[@Ruben-ht5op]

I dont understand shit of what he is talking about, but this looks hella cool!

[@indnaresaki8905]

[@kokomabanding5655]

Cool circuit drawing

[@toyotahiace4515]

I dont understan everything he says but still watch to se the end result

[@viermidebutura]

you absolutely need feedback for the tesla ciol because by simply being to close to it the resonant frequency changes as for feedback you can use a current transformer or you can use an antenna

[@Vanoxian]

this is really enjoyable.

[@annemariemiguel2541]

Hey great Scott can you build a amplifier? That would be cool

[@jf41012]

By the way were is your promised guide for pcb carving with the x-carve cnc? Just watched some old videos and noticed that you've never done it :D

[@MantisRay861]

Question for you: Do you have to use two separate power supplies for the gate drive IC's? I saw on another Full Bridge inverter circuit video where it was specified that they MUST be separated. It didn't make much sense to me, since they're really just switching voltage on and off to the IGBT's.

[@anklebiterwoodworks2818]

Love the projects. I eagerly await each one! One question I have had for a little while is this: how many times did your eyebrows have to grow back while playing with all this electricity? LOL!

[@greatscottlab]

None. But I got shocked twice.

[@jantsbenzproaudio]

Can you make a video on how to make a emergency light that lights up when the power is thanks... Your videos and project are all awesome!!

[@DoRC]

it seems like 50c would be just fine for the igbt. why did that concern you?

[@TeslaNick2]

Amazing work. I've been desperate to build a SSTC for years, I've mastered spark gap coils with great success. The only problem is my lack of expertise. You make it look so effortless. Are you going to publish the final design of the driver circuit ? I'd love to knock up a PCB layout for it. Up for a deal ?

[@leonpakar6077]

did you make anything, i am trying to build it atm but have a few problems with the circuit

[@TeslaNick2]

@@leonpakar6077 I never got around to it. I stuck with spark gap coils.

[@xaxaxaaxaxax]

maybe you need a freewheeling diode across the igbts to avoid the voltage spikes, since the igbt does not have a inherent body diode like mosfets do; without the diode the voltage spikes can easily exceed the reverse breakdown voltage of the base-emitter junction, which has a much lower breakdown than the base-collector junction, and heat up the igbt or damage it

[@Biela2008]

Hi! GreatScott! Can upload some footage about the coil when it has a corona discharge like arcing in the dark? I'd would really like it! :D

[@segarlinktech]

excellent project

[@indiancreator6904]

hey Scott I have an idea for you that you can assemble all the parts that you used in projects and just sell it on amazon and eBay

[@ML-iq6ly]

I really like your videos. Could you make a video about your power supply (ps3020)? Your videos are great 👍👍👍👍

[@pirateskeleton7828]

Love this project! Curious, would you consider adding capacitors as low-pass filters to the Arduino's potentiometer analog inputs?

[@cyborgsheep6077]
