Thank you :-) I will try to make this coil into a more finalised version, but you know, the older you get the less free time you have... Also the motivation with this coil is quite low because I still cannot get it to produce straight sparks.
@@jmartis2 You are just an amazing guy with great knowhow for building these awesome Tesla coils. Me too, I'm turning old but I just can't stop doing those diy's Tesla coil at home. I found success after many failures wasting tons of money on MOSFETs & IGBTs. But finally my son & wife are both happy with my Tesla coils. You are way higher on the top level. Just keep it up my friend.
Holly shit! What a marvelous Tesla coil. This is indeed a great work of art & I must say that I have to bow in front of your talent. You've reinvented the nature in terms of electrons! Your TC is showing electrified tree trunk with its leafless branches! This is what I'm expecting to see from all those who are building their Tesla coil. Great DIY man. Hats off to your amazing work dude. Keep it up. It'll be kind on your behalf to share the schematic for others to try same if of course they can. Your Tesla is like the summit of perfection. My God! I'm without words!
@@jmartis2ello I have a doubt. So I made this secondary coil back in 8 th grade It's about 70cm and 6cm in diameter with about 800 turns 😅😅 I think the coil is too thin How to determine the width of the coil? Is there anything specific? Will it work good?
Hallo jmartis2, i'm working on a drsstc, too. Please could you put a link to the video description where we can find the schematics for this monster. The circuit you created must be state of the art as it produces those gigantic discharges. Very impressive, good work. Greetings from Bavaria.
I found that (on my mains ramped vttc, but I think it still applies here) the odd super branchy ends happened at a small interval of detuning with the primary at a higher frequency. Just a bit above or below this interval, the streamers are smaller and quieter (until you stray far enough back in tune). This even happens at very low powers for me, even with streamers only a few inches long. I got results very close to the ones around the 1:12 minute mark, although much smaller and the branchy-bits were smaller.
In a VTTC, this often happens when the coil switches resonant poles during operation, which produces an abrupt change in power. Of course, this happens in a narrow tuning region, outside of which the feedbacking oscillator reliably locks on only one of the poles.
Thx 😊 I believe the tank cap in this one was around 15nF, the coils changed but I believe there is 265kHz written on it 😀 that is the secondary resonance I think. The primary was tuned slightly below that.
Just A W E S O M E!!!!!!!!!! 😮😮 I mean, WOW, from a 25cm coil you can get 3 meters sparks! I understood well sgtc and SSTC, also DRSSTC, but QCW DRSSTC are still unknown to me... How is it possible to get a so long discharge in the "free air" without having them striking the ground or the bottom of the secondary coil? Then, last but not least, could you share the schematics please? Thank you a lot and happy new year! 🎉👍😃
Its possible because of the long on times of a QCW. The spark grows gradually over around 10-20ms. It doesn't strike the ground because its olny at around 50-100kV so it breaks out at the breakoutpoint on top and then grows through the already ionized air. If you want to build one you can't just ask for the schematics. A QCW coil is a special type of a DRSSTC where the primary current is gradually ramped up in a linear ramp which is generated by a powerful buck converter or a phase shifted full bridge. At least thats the basic principle but building one is much more complicated.
@@felixb.1756 Wow!! Thanks a lot for the explanation... I never want to build one cause I'm just 15😂... But anyway I'm really into electronics and I like know how things work. I only build by myself lo power stuff like amplifiers or small SSTC drivers or ZVS oscillators everything under 300 watts 🙃
@@fabriziobrutti1205 haha sam im also 15 but already built a 4kW RSGTC (I posted a video) and im designing my own phase-shift QCWDRSSTC driver at the moment.
@@felixb.1756 Wow! So it seems that you have more possibilities than me😂😅... I live in an apartment building in Turin, Italy, and here we just have 3kw breakers and no space for big projects 🙄... Since the house wiring are the same for 16 families (in my case) I feel as if I have to be also careful with EMI, and so more than a few hundred watts SGTC can't be built... I have MOTs, big caps, lots of wire... but just can't use them 😕
@@fabriziobrutti1205 thats a shame! I live in Austria in a house with 3 phase 16 amp breakers so yeah its possible to run 4 mots in a sgtc without a ballast. But im currently more into QCWDRSSTCs or DRSSTCs in general. They dont need as much power and don't profuce a lot of emi so I think a QCWDRSSTC should also work in your case but it get quite complicated with the gigant buck converter or complicated phase-shift driver technique
Are you going to post this coil on the High Voltage Forum? Would love to see more details - frequency at start and end etc. Perhaps some of that info is in comments that I haven't read yet.
Hi, I will do this when I finish the coil. This one is still under development and I'm not sure for how long... The problem here is extreme detuning which prevents long straight sparks. I have tried using ferrite core inside the secondary and rewinding the secondary, which helped only a little. I'm still not satisfied with the result and now have other work and projects, so sadly this one is now on hold...
@@jmartis2 Understand. I too keep interrupting projects for others. Many people post to High Voltage Forum as projects progress, but that takes extra time.
I would say not easily without a lot of experience with power electronics and Tesla coils... I have started about 15 years ago and built maybe a hundred coils (including the experimental ones) and designed a lot of switching power supplies. And even now it often happens that a coil doesn't perform as well as I thought. If you have little experience with coiling, start with something simpler and slowly work your way up :-)
@@moonmatthew Spark gap, vacuum tube, or variants of the "slayer exciter" circuits for solid state (there are a lot of them a some using MOSFETs can be quite powerful). Then you can continue onto a simple non-interrupted half-bridge SSTC, there you can really learn the basics of power electronics. You can also try building solid-state "flyback drivers", this is where I also learned a lot.
Hi Jmartis2, I just like your coil, so Powerful. I might try to experiment with Sic Mosfet as well. Could you explain the gate drive for Sic? What is the power of your auxiliary power supply? Thanks in advance and keep on marvelous job.
It is from a relatively common 400VAC 3-phase outlet, draws around 18A per phase (will run from a 16 amp breaker for a long time). The 800VDC is provided from a boost converter which also improves power factor.
sorry I have no idea... I imagine the cost of the parts when new was really high, but many of them were used for a fraction of the price, some from my university...
By "quad SiC bridge" do you mean 4 transistors total - or do you mean 4 in parallel as each leg making 16 total? Also - would really love to see a writeup or some build informaiton on this beast! This is my coil goal
Hi, it is 16 transistors :-) Actually 4 separate bridges which are paralelled after a divided tank cap. I was being paranoid about current sharing. This coil was not performing as it should so it is still in development, but it goes very slow with me. I will then put up some info on the high voltage forum (as I did with the first QCW).
You still did not reached for the limit, if you want to do that start using bipolar primary's and theyll have to be like double helix with top and bottom attached to eachother like the normal bipolar pancake coils!! Copper tubes

Thanks :-) The energy storage bus voltage is 800V (starting), but drops to 600-700 at the end of the ramp. The peak RF current reaches 250 amps.
