FlyBack Driver with transistors D718(NPN) Make Powerful 60-100kV ,A High Voltage Generator DIY

[@tauqeerahmed8835]

This experiment is authentic. I try it myself and it works . Spark is awesome at 18v

[@kenw.1112]

Good video. You can use 2- horizontal output transistors for this . 2-2SD2634's they are high frequency sweep transistors . All you have to do is look up the specs on which transistor you want to use. I like this set up because of the HI. Voltage output you are getting out of that integrated flyback transformer. Your not going to get much more than around 27,000 volts DC (27kv) because those flyback were designed to run around 19kv-30kv tops. If you try to push it past 30kv substrate /insulation breakdown will occur.

[@fungusenthusiast8249]

tried this with a d2645 transistor at 15v. works well. Edit: just blew the transistor. would it be ok to use d2387? only difference is a lower base current (0.1 A vs 0.8 A) Edit: tried 13007 transistor and it works so well, it doesn't even need a heatsink.

[@Deadman1070]

You used a single transistor or 2 in parallel?

[@prateeksingh7196]

Heyy can you help me

[@danielengsvang3126]

The question is, For How Long can you keep this driver going before frying/killing the transistor/transistors.

[@lordelectron6591]

Till it transistor overheats and gets permanently damaged

[@lordelectron6591]

Well if you are planning to arc it for long use cfl electronic ballast with cooling fan and if you can add heatsinks to the transistors present on the board of the electronic ballast it would give better performance (as cfl electronic ballast is designed to work continously. It's more powerful than some of the zvs drivers out there Also put external 12 turns for primary coil)

[@uK8cvPAq]

It's the one question that never gets answered when people post these flyback drivers.

[@indrayunarta]

12 lilitan dengan diameter kawat 1.0 mm?

[@szer3778]

Actually they didn't make 8 and 3 turns, but 9 and 4. The wire crossing the ferrite loop counts as one turn. Viewers should add one turn to replicate the circuit.

[@BdM007]

ok thank for your idea

[@anushkadeepanideepani5593]

Woow absolutely Amazing work you are very good tichar God bless you

[@pakulum8628]

laila haillallaaaaah...... besar banget kluarnya strum di output nya...... bagus banget..... wassalam semuanya......

[@electricalengineeringvideo1637]

Woah! I haven't use magnet wire as primary and feedback coil, I didn't know it's more efficient than an ordinary wires. Can I ask what's the input voltage? And why didn't you add fast diode? It would protect your power transistor from the flyback's voltage spike

[@TitiProsopel]

Nice ...tks man for video 👍👍👍

[@demonic477]

back when we had to repair CRT's there was a reason we were told to leave the flybacks alone this is why they will kill you fast 10.000 volts in most cases more in the larger units is nothing to play with

[@СталонеСильвестров]

It is really great !!!

[@lindacastro9303]

you should try using a nail clipper ..

[@agiltonjunior3802]

And the resistors each have 5w of power, putting the two together you have a tilerance of 10w of power because 5+5 is 10 so in this case you have a resistance of 10w, right?

[@rodrigomartinez6132]

The video was good but not showing the voltage source transforms it into a useless video.

[@armanlindayag7084]

Sir is it possible to use D1555 HOT to drive flyback using 12v supply

[@uK8cvPAq]

Wow those are some big old sparks there!

[@eksnew2682]

Nice channel, flyback video I like you. Keep it up

How many toltage battery that you use ?

[@chadgrimes5119]

Can input a voltage more than 12vdc to the circuit or it can take more than that let's say 15vdc cause that's what I have right now

[@rangiroa100]

Hi BDm007. What is the purpose of making an extra coil winding on the outside ? Is this possible that you could use one of those pin to connect to your circuit instead of making extra coil ?

[@danielengsvang3126]

On the outside?. I don't know what you mean really but i think you mean those two windings on the Ferrite. One is Feedback And one is Primary. Feedback winding is connected to base of the Transistor, To "Drive it"/ Open. electronics.stackexchange.com/questions/377753/understanding-a-single-transistor-flyback-transformer-driver. look here

[@pablocustodio7890]

can i use this fore electro fishing

[@carlosdelacruz6626]

What is that sir,baterry operated or 220 house power use.

[@agiltonjunior3802]

And with two transistors, the flyback power increases more, right?

[@mikew.inversegravitycraft]

Why do they wrap the copper wire around the core?

[@sidewinderam9m]

I just tried this but I only got around 10k volts at a much higher frequency than in this video. Also without a heat sink the transistors were far to hot to touch after only 4-5 seconds, which makes me wonder if this could be used for any length of time. The website in the link shows a 12v source voltage, I tried at 24v but the transistors wouldn't switch at that voltage so I would probably need different values for the resistors in the voltage divider. Also 5w resistors seem totally unnecessary. My 1w resistors seemed to do just fine.

[@uK8cvPAq]

24v = 560 ohm and 22 ohm.

[@sidewinderam9m]

@@uK8cvPAq Is that just based on the necessary base/emitter voltage?

[@uK8cvPAq]

@@sidewinderam9m Yes, it forms a potential divider to bias about 0.7 to 1v on the base of the transistor.

[@carlosmoyamendoza6835]

Whats the name of the Melody I like it

[@agiltonjunior3802]

The source you used is 12v, right?

[@shaolinmatadordeporco2856]

great video

[@imagine_laabs]

Make zvs instead. Much cheaper and efficient.

[@szekerespista3758]

Nikhil Jagtap Why? Could you please explain?

[@lordelectron6591]

Even more cheaper buy a cfl electronic ballast

Nice work good job,I wanna ask you about the transistor D718 what volt should I get ? cause transistor has deference voltages. “Dose it depends on the input I supply“?. And thank you.

[@BdM007]

25V is good!

[@bernardolopezd8905]

Este circuito se puede hacer con cualquier flyback o no? y se puede hacer con el transistor 2N3055? o tiene que ser el transistor D718 Espero su respuesta gracias y dios que la bendiga Bernardo L D This circuit can be done with any flyback or not? and can it be done with the 2N3055 transistor? or it has to be transistor D718 await your response thank you and god bless Bernardo L D

I have a better way than what this guy shows. I use a horizontal output transistor a driver transformer and a driver transistor to drive the H. output xsistor. I have a horz. Osc. Ckt. That runs at the 15,755hz. And runs the driver hence powers up the integrated flyback transformer. Works great producing a DC hi. V. Of 18,000 vdc-25kv-dc

how is the circuit you use.
