Thankyou for the videos I have only made spark gap coils before with about 1000mm sparks You have given me the motivation to build a solid state coil I look forward to your next video When i get my new coil working i will share a link with you with the finished coil
Thanks for this great series, you motivated me to go ahead and fnish my tesla coil. It was sitting in a corner for about 2 years now. I took your driver and modified it slightly to work with my coil and the components I had lying around. (I hope this is okay) Works great :) Greetings from Germany.

@@oniruddhoalam2039 just safety concerns, like the worst case the ground disconnects somewhere. Also, you don't risk damaging any load connected to mains (neighbours etc.)
You should not use house ground, it has a way too high impedance. It is better to roll out some food aluminium foil on the ground and make your own artificial ground plane.
I wrote an article about grounding and EMI for Tesla coils: kaizerpowerelectronics.dk/tesla-coils/drsstc-design-guide/grounding-circuit-protection-and-emi/
Congratulations. On my induction cooker, I was able to run continuously at 530W. I burnt my IGBT after reaching 850W (after 2 min of running). Though from mains, the power drawn was 850W, the current in coil was 20A (I use FGA25N120 = 25A). I have a current probe to measure current, but did not measure the voltage across coil. Also, the heatsink in my case is much smaller, which was causing the IGBT to heat up extensively. I am still guesing if the failure was due to over temperature (and hence sideeffects) or over current spikes?
I have a question: Where the sparks go? They seem to quench in the air. Also, some points. 1) for the shunt you could try a chunk of thin iron wire. 2) Is the bandwidth of that pocket oscilloscope enough to read fast peaks? If the bandwidth is not high enough you end up seeing smaller voltage peaks than real, and the fact it does not change much after removing one capacitor could be a hint that the peak is lost because limited bandwidth. Could it be the case? 3) I wouldn't trust much the insulating properties of that keypad or of the LCD display.
1) Capacitively coupled to ground through the air. 2) You are right, the ADC of those handheld DSOs can hardly do 1/10th of their specified bandwidth for a square wave, its sad, here I test the DSO138: ruclips.net/video/-Eqaadcnhn0/видео.html 3) The voltage in the primary circuit is only around 600VDC peak-to-peak from 230VAC mains, if this was a DRSSTC, the voltage would be much higher between the L and C of the primary circuit, I would not trust it either, but failure is not around the corner to knock through the plastic at only 600VDC.
Your doing a great job with this. Your certainly more skilled than me. I dont know much about transistors, which is why i made my coil spark gap triggered. But i plan to experiment with a solid state driver on ebay. If i can trust ebay that is.
I'm loving this series, thanks very much. I would like to leave a suggestion. For those who are not inclined or don't want to build our own circuitry, what about if you make (or just suggest) a tesla coil out of parts found on aliexpress/ebay? There's a ton of different drivers there but almost no information about how to use them.
Instead of a resistor to measure current try using a wideband current transformer. Permalloy coil (from old ground fault interruptor) and terminated into a 51R resistor at the scope input with some shielded coax cable as lead should give a much better current waveform. You can also calibrate the coil using the inverter, using a high power resistor ( like a stove element, though that will be slightly inductive) to get a defined current flow through it.
DiodeGoneWild It seems odd that you have the 18v zener diode going directly to ground. Wouldn't that allow a very high current through the zener if the emitter-emitter junction of the BD139/140 ever went above 18v? Perhaps a small current-limiting resistor between the emitter-emitter junction and the zener would be better?
I got a question, how does this circuitry stays in resonance? I don't see any feedback circuit. Once there are sparks coming, they basically change coils resonant frequency and whole system goes out of tune.
As far as I know, you might get sparks from the base of the secondary if you don't ground it. You really don't want those arcs to hit the secondary or the primary.
Great job there, but Im interested in this question: why, once I start my tesla coil, any electronics in a perimeter of few meters, stops working properly. Not able to take a video like this, for example, the phone starts all possible apps and zooms in and out by itself and etc. The TC is with simple circuit powered by dc voltage (19,5V), it is SE with a single cap, a resistor, mosfet(irfp460) and potentiometer. Sometimes it powers up a neon sign a few meters away, sometimes I need to bring a luminescence bulb very close to light up... the snake(due to Ancient Egyptian hieroglyphs) I have managed to get is no more than 5-6cm long, but hot enough to melt steel and strong enough to leave a lightning scar on wood, but I dont really understand what and why it happens. Would you please explain. Thanks.
RoboT thats right, but something is wrong because nothing matches. For example: same voltage - different perimeter of influence; small tentacle - big radius, small tentacle - small radius (because trying different materials (iron, copper, bronze, aluminium) for primary coil); big tentacle - difference again.
I have a quick question about repurposing a microwave oven. I need an isolation transformer, would it make sense to take 2 microwave transf. and remove the high voltage winding from one and use the low voltage winding of the other to make a 1:1 isolation transfo? I guess it will be at least 600VA?
@G E T R E K T 905 thanks, that's what I will do probably, it will be the same wire anyway for both windings so I just have to spend an afternoon doing that... 😂
Hi Dan! I've recently finished making the halfbridge and now I have a new toy :) Here's a video of driving a HV trafo with it: ruclips.net/video/Y9YJnGhXjLw/видео.html Transistors are almost cold :D
@@vaclavtrpisovsky Thank you so much! This software is just what I was looking for! I used another open source software, but that one was very buggy and would crash a lot.
If you mean it has to be loud, then it's definitely not as loud as a SGTC If you mean it's a big *load* - it only draws 3A RMS from 230V mains, a hair dryer draws more :)
SSTCs has a much lower peak current in the primary circuit and the voltage/current rise rates of the secondary coil spark output has a more smooth sound. SGTC and DRSSTC has very high peak currents and that makes them MUCH louder. The difference in primary peak current is also at the other of 20-40 times higher.
My native is Czech, I understand Slovak, because it's very similar to Czech, I hopefully speak some English, and a bit of Russian and a tiny bit of German. And I also manage to understand a bit of Polish and Croatian because it's somewhat similar to Czech and Russian.
Hi! WAS WATCHING YOUR VIDEO ABOUT NIGHT VISION. COULD YOU MAKE ONE FOR ME, IF YOU ARE OK WITH THAT HOW MUCH IT COULD COST WITH ALL SHIPING? Or may be you are Ok to send your made one, I'm Ok to pay first. If I would have skills like you do, would make it my self.
You should lower the primary inductance (fewer turns), turn down the BPS and get some longer arcs. I got up ~50 cm discharges from my SSTC2 seen here: ruclips.net/video/cMz4_MIfcYM/видео.html and what about your handheld oscilloscope, what is the band width of it? I doubt it can truthfully show a 400kHz square wave. That is why You might see those superimposed sine waves on the high frequency signals, the ADC can not do the job. For others that want to build SSTCs I have collected a few basic theory calculations for the inverter design: kaizerpowerelectronics.dk/tesla-coils/sstc-design-guide/
I definitely plan to try fewer turns on the primary. The handheld oscilloscope says it's 5MHz 20MSPS. This secondary runs at 142kHz. The oscilloscope should be able to somehow display it. The voltage waveforms look like a nice square wave. I have already googled into your website accidentally several times during the last decade :).
I reviewed it in one of my videos: ruclips.net/video/gCI0S3Bcofc/видео.html It's called DSO FNIRSI PRO. Of course, your website contains quite a lot of useful knowledge ;).
@@DiodeGoneWild It would be interesting to see what the input CLK is on the TLC5510, this clock speed is the amount of samples it can do in the falling edge. So if it was running at 20MHz as the datasheet example, it should be able to get 40 samples on a 50/50 dutycycle, but if you are looking at primary current interrupted at 200us, that is properly down to 0-1 samples. So you can not trust this to show a squarewave at low on-time at 500kHz. But just in case I am wrong, could you try to do a test with it hooked up to a squarewave generator sweeping it from 100 kHz to 5MHz?
Do you have a portable AM radio? I like to know how many kilometers you have to drive out of town before you cannot hear those sparks. Your GF can do that while you run the machine😁

The sparks are diferent than the spark gap, why dont you make oscilate based on a feedback from the secondary like the slayer exciter circuit
Mabey u can boost mains voltage to make sparks bigger
He might upgrade it to a full H bridge or make it a DRSSTC

Why not use a current transformer to measure current? With higher frequency you won't need that many turns on a toroid..

You can actually get something called the diff probe it allows you to to measure High Voltage without damaging your oscilloscope

How would a "Induction Heating Power Supply Module "from banggood ,work as a driver for a Tesla coil ?
Those are usually only for low input voltages (max 48V) which is not very practical.
Those use a ZVS topology, not particularly useful for an SSTC.
could you use the same driving circuit for induction furnace?
Yes, you just need resonance capacitors, an impedance matching transformer. Also run it at full wave/CW
