In this video we will show you how to make a powerful Tesla coil running at high frequency with beautiful sword like lightning discharges.
Here is a link on the construction details and the circuit diagram:
teslascience.w...
We test the tesla coil in this video with some amazing wireless power transfer effects. The driver which is a ZVS Driver or Mazilli Driver can be cheaply bought for about $30. It is also easy to make. The coils can be around on PVC pipe.This video shows a sturdy self-contained unit that can be just plugged in to a variac for sword arcs or DC switching power supply for near silent continuous wave operation at high power.
The negative rail is common (join all negative connections together) and also join them to mains ground- in my case the mains ground connection from the variac output. The bottom of the secondary coil is connected to mains ground or real earth ground. Either one is fine!

Going to make a self running generator with this device. I have an idea how to make it. 3 sparks gap and ground vacuum will work well with your device. New field energy of the real Maxwell theories. Great project. Thank a lot. Brilliant

Great info with altering the capacitive value 👍🏻

@BrianDhvTinkerer 2 года назад

Thanks I appreciate it!

@TravisTellsTruths 9 месяцев назад

Awesome!! His stuff is crazy. I'm going to try to make one very soon. A special type of thing! All I need to do is learn how to use either of my 2 tiny oscilloscopes for tuning.

@vdekjEE 3 года назад

Glad to see it's working well! Maybe I'll give this a try at higher powers soon.

@MrAngellael 3 года назад

can 127v be used with mosfet irfp460 or igbt?

@hadzrinekosni4530 2 года назад

I've notice in your circuit diagram that you use 100 ohm not 470 ohm as usual for gate.. is there any deferent result.

@BrianDhvTinkerer 2 года назад

Yes it’s improves performance if the gate has a separate 12V power supply. It no separate gate power supply, then 470 Ohm is best.

@Magneticitist 3 года назад

Morgan put me on to this and it's pretty cool. Are the two coils exactly tuned or is the secondary a little higher accounting for breakout? I was on a push-pull binge for a while, they are great for lower voltage SSTCs.

@BrianDhvTinkerer 3 года назад

I am happy you Found the experimental details helpful. Initially, to the primary and secondary Coils to exactly the same frequency. Then test at lower voltages. This is best done with variac.

@BrianDhvTinkerer 3 года назад

You should see output. Then move the tap point on the primary such that primary resonance is slightly lower in frequency than the secondary resonance to allow for resonant rise. This takes a bit of messing with for best results. You can get much bigger arcs this way.

@RAVI171175 2 года назад

Thanks man for sharing this video. I've tried it out & your circuit does indeed work. With only 12 v at the gates, it's transferring energy wirelessly. I've done the same coil with same setting but I'm only getting about 1 cm spark. Everything is same as yours. What can I do to get bigger sparks? My secondary & primary are both resonating at 330 KHz. If I go about 50 VAC from my Variac, my mosfets dies. I want to get bigger sparks like yours but I'm not getting it despite both coils are resonating at same frequency. What can I do big bro? Any suggestion?

@BrianDhvTinkerer 2 года назад

Did you try to use rectified AC input from the variac. I use parallel set of 10A10 diodes on one of the variac outputs and have the positive half wave rectified AC go to the positive input of the ZVS. This gets much longer sparks. Next try subtle adjustments in the breakout such as lengthening or shortening and adding foil or stainless steel balls to the breakout. Subtle changes in primary tap point position also help. Make sure base of secondary is well grounded.

@TravisTellsTruths 9 месяцев назад

When you say grounded, do you mean earth ground or a fake one/metal sheet/artificial ground.

@hyparh Год назад

I made one too and it works nice. But I'm curious about one thing - it consumes around 150W, but when I'm playing with the sparks it can go over 360W! Mosfets (IRFP260) are getting pretty hot on a big heatsink (must add a fan). Is this big jump on consumption normal when I play with the arcs and why it is happening?

@TravisTellsTruths 9 месяцев назад

Better resonant power transfer at better tunings I'd imagine

@EnterTheRealm 3 года назад

Amazing. Thanks

@BrianDhvTinkerer 3 года назад

Thanks man. It was a really fun project!

Thanks. It is a whole lot more efficient the. Using a ZVS driver to power a spark gap Tesla coil.

@johnnycash4034 2 года назад

Very cool 😎

@juntendo6104 3 года назад

Isn't it bad to ramp up the voltage on the ZVS driver? Few of my ZVS drivers from china died because of this mistake I made

@juntendo6104 3 года назад

NVM I didn't know you were using separate supply for gate

@nirvana2117 3 года назад

Hey man do you think I could power the zvs driver with 9v batteries or do you think I'll kill it?

Needs 12V min to run!

@juntendo6104 3 года назад

Can this thing run on full wave mains instead of rectified half wave? or is that too much power?

@BrianDhvTinkerer 3 года назад

It will run on full wave rectified mains but mosfets wil get hot at higher voltages

@travisbfsj 3 года назад

I use 2 18 volt drill battery's in series works great 18-19 volt is the minimum i use with that driver I have a video comparing the difference

@theGraphicAutist 2 года назад

if the variac is pushing AC how are u able to share common ground with driving circuit?

@BrianDhvTinkerer 2 года назад

It’s grounded to the mains ground (the variac I’m using has a mains ground). The base of the secondary is grounded to earth ground or mains ground. I’m using a metal rod in the ground but mains ground works fine for the base of the secondary.

@theGraphicAutist 2 года назад

@@BrianDhvTinkerer TY for responding so fast! so where does the other variac wire go?

@BrianDhvTinkerer 2 года назад

@@theGraphicAutist The ground of the variac is connected to the common negative ground. The AC output of the variac goes to the ZVS. One of the AC inputs is half wave rectified to get AC ramping.

@theGraphicAutist 2 года назад

@@BrianDhvTinkerer so I have earth ground of variac connected to mains ground along with base of secondary coil, one of the variac output is rectified then to chokes of zvs... do I just leave the other variac poles not connected or are you saying hook that to earth, cuz I am no EE but that seems wrong lol!

@BrianDhvTinkerer 2 года назад

Imagine the two outputs of the Variac just connected directly to the ZVS instead of DC input. Rectifier is connected between one of the variac outputs and the positive input of the ZVS such that the rectified input is a unsmoothed positive. The other variac output is connected to the negative of the ZVS. Forget about grounding in the beginning. Just ground base of secondary to mains or earth ground

@spandandutta2485 3 года назад

replacing the fets with igbt s might give some extra power..... i think the fga60n65smd will do great.... a 100 v run i guess !!!!!

@BrianDhvTinkerer 3 года назад

Worth a try. I could power the gates on the IGBT modules with a 24V separate power supply and crank the puppy up 😂

I only every use IGBTs in my zvs (and can run at mains input :)), so if I try this I'll let you know the results. I had tried it before, but my setup was worse back then and I killed several IGBTs.
