Building Spark Gap Tesla Coil pt. 2 - High voltage transformer / power supply

[@robson6285]

First time someone explains understandable how a magnetic shunt works! I never found out the working till now, so thanks! You are really a great explainer! (pc power-supplies came also reálly clear to me, thanks to your channel!(Áll their circuitdiagrams, so much thanks for that!!))

I know that due to the COVID emergency you can't go out to buy thinghs that arent strictly necessary, but I think that pouring the transformers in mineral oil would help preventing arcs and cool them down. Can't wait for part 3

Its funny that electroboom just did a video on a spark gap where it was in series instead of paralell to the source

[@markiangooley]

Yes. He first showed a Tesla coil circuit with that arrangement and then modified it for a spark-gap transmitter.

[@bashaaksema94]

@@markiangooley but why was the one on his in series? Instead of how diodegonewild explained it

[@omniyambot9876]

@@bashaaksema94 he's just using it to add the voltage, here diodegonewild already have very high voltages in series but he also did parallel for a total of 4 transformers so he could still supply high current for another primary which is the aircore transformer.

one time I opened up a microwave to get an MOT and I found a switch mode power supply with a step up transformer so that the transformer was more efficient.

[@superdau]

A lot of recent microwaves are inverter based. It's just a lot cheaper to build because you need way fewer materials.

[@Stoney3K]

15:10 years ago i made that power supply for my tesla coil and it works very well, it is whole in oil and with some small coils in the secondary to limit the current a little ,and it works very well. nothing gets hot.

[@markiangooley]

At least nowadays nobody uses PCBs, just mineral oil...

[@keithking1985]

i was watching a documentary on termites last night, & it showed an exterminator using a GUN that had long tip with arc's going into the tiny hole's in the wood the termites made. CRAZY!! COOL GUN DHO!! cant wait to see the cap!!

[@Miata822]

That's a serous power supply. Be careful folks.

[@johnoddvar1967]

For safety measuring could you try to put a lightbulb between the 220 input and then conect 220V to the secondary. i think its more safe to use the transformer as a stepdown to measure. I realy love your experiment you learn me a lot. I wasnt wear of this magnetic shunt. We use it in my work, but i have never heard of it before.

Len tak ďalej, držím palce :) Sorry if I was wrong

[@SimplyChem32]

Perhaps transformer / mineral oil would assist in providing the necessary isolation for those transformers?

[@DiodeGoneWild]

Yes, somebody actually tried to put 6 MOTs in series and put them under oil. It worked, even though I'm not sure if this can be reliable in a long run. And a giant container with 6 MOTs and many many liters of oil isn't really the most practiacal thing to move around :D.

[@sFeral]

Explain the difference between Yours and ElectroBOOMs arrangement/schematic.

[@sFeral]

and what if you were to put another capacitor in place of the gap, while making sure the resonant frequency of the LC circuit is constructively interfering with the source 50/60Hz ?

[@regulareverydaynormalguy6479]

He already explained it in part 1, It can damage the transformer because of the high frequency .

[@sFeral]

@@regulareverydaynormalguy6479 lol something must have deterred me from watching the first part till the end.

[@sFeral]

@@regulareverydaynormalguy6479 I've seen people mix these schematics before, it's just easier to refer to EB now, since his channel appears to be gaining popularity and is somewhat in sync thematically. Diode is much more technical and just a tiny bit less comical.

@@regulareverydaynormalguy6479 Actually I'd like to see him explain all possible arrangements (with and without the gap), which includes the parallel cap being closer to the air-core primary, hence in series with the second cap.

[@tunderbird123]

Wow...I wanna see the results!

[@Max_Chooch]

When you're using 240v, you have 2 hot lines coming in. With your 2Mot and 4Mot diagram, you only have 1 inductive resistor on 1 leg of the incoming 240v. Is there a reason you didn't diagram or use another inductor on the other leg, too? Is one inductor on 1 leg (provided it meets what you need) enough or would one on neach leg be more symmetrical and effective at limiting the current so as not to blow breakers? Is one MOT with the secondary removed enough of a ballast to keep the 2Mot 240v setup from tripping 30 Amp breakers?

[@solarsynapse]

12:46 Does it need the ground? Is it input mains ground or output RF ground? Both?

[@grima0482]

Would it also be possible to connect two pairs of MOTs to 400V (between two phases) with the two pairs connected in parallel to the 400V mains supply and each pair consisting of 2 MOTs connected in series to run each MOT at 200V which would take them out of saturation. This would reduce the current draw from the MOTs and also reduce the copper losses in the primary windings as well as the eddy current and hysteresis losses in the core.

Hei. Would a 12kV, 20mA work just fine also. With 2 secondaries connected in series of course

[@smiley235]

Hmm, I’ve got a 900VA 9000V neon sign transformer that’s been sitting in the garage for 15 years, this is giving me ideas...

[@not8994]

How would you match the phase of 3 MOTs?

[@KuntalGhosh]

put them inside a tub of mineral oil or transformer oil if u can find some ... & use the thermal cutoffs from the microwaves to protect the transformers by putting one on each coil ... and put the whole assembly inside transformer oil .. it would increase the isolation voltage to 20kv per mm

[@KuntalGhosh]

20kv per mm if u use fresh oil and clean the transformers , the oil can also be used to cool the transformers if u do some tubing to all of the coils and add a pump + small radiator , u could use the setup all day long and not overheat !

[@solarsynapse]

I was thinking I could connect the HV out wire of 1 MOT to the core of a second MOT for a series circuit. Insulating and isolating the cores from each other, ie don't mount to a metal platform. I don't understand why the HV secondary is connected to the LV primary.

[@leozendo3500]

Very very helpful information.

[@kolinevans9127]

I was going to say there are shunts in a oven trans but I think the fact that the unit primary utilizes up to 100s of Watts just running does not help. I’d love to see a tube version, I’m learning tubes.

[@cronauer1985]

Are the microwave oven caps polarity sensitive?

[@psycronizer]

Mr DGW...what about using a spark gap in a partial vacuum ? to get around having to use more M.O.T's and thus making it less lethal ?

[@leonidaspetridis3744]

how can i make Inductor coil?

[@Broken_Yugo]

Could the doubler circuit that comes with the microwave be used with a single transformer for a small coil?

Yes I think you can...but maby you have to limit the output of the multiplier with a resistor.

[@mabul513]

If doing a microwave oven transformer would cutting a slot in I bar and pushed up primary and put steel in air gap would this work better than if you chopped it down to primary coil? What's stronger as cutting a 2mm gap twice in I part of transformer has a lot more steel surface area?

[@dawsondavis1340]

Pretty sure Electroboom did something like this but used his own HV Capacitor and air core inductor, but let’s see how diode does it

[@Z-Ack]

Yea kinda odd that diode said spark gap last video and what was electrobooms vid about the next day? Kinda fishy.. but youtoobers tend to work together , or at least the good ones., well i guess all those lame fake toobers all gang bang eachother for views themselves so eh..

[@samhoff1724]

Can I use DC flyback with zvs driver?

[@redoverdrivetheunstoppable4637]

well... yes, it's ok for a small one, the best transformers are maybe from PC monitors, they already have an high voltage capacitor inside of like 2nF, its ground is on a separate pin usually, and the positive is always connected to +HV, the capacitor value is around 2nF and you can't change it, otherwise use an external capacitor without connecting (or having) the internal one.... i'm planning to build that

[@jessicaganser2982]

Yes but I would then recomend powerfull flybacks becaus smaler flybacks can overheat.

[@samhoff1724]

I ordered a powerful flyback and made some big capacitors. Thanks for the advice!

[@jkobain]

You mentioned the designs where they swap the capacitor and the spark gap, and guess what type of circuit did ElectroBOOM show us in his latest video?…

[@lancemgy]

@@morganelectronics And EITHER method works just fine, for a Tesla (or Oudin or any resonant air core xformer energized with a spark gap) or a transmitter. Even Tesla himself drew schematics with the gap in series, and given the power levels he was working with, I'm sure he would have been ruining xformers all the time if what DGW says is true.
