Thanks for this video practical. My suggestion please try to make like Iron core transformer (input 220v ac and out put 12v 4A or more)in ferrite core, is it possible? আইরন কোর ট্রান্সফরমার যেমন ২২০ভোল্ট এসি ইন আর আউট বিভিন্ন ভোল্টেজ এম্পেয়ার করা যায় সেরকম ফেরাইট কোরে কি করা যায় না? তাতে ছোটো যায়গায় SMPS না করেdirect transformerবানানো হলে সুবিধা হয়।
It is not constant DC, bcoz, one end of the 7-0-7 primary winding is giving the feed-back to the base of the transistor 2N3055, which makes it oscillate (switching it ON/OFF at a high frequency), ..thus the Hi voltage is induced into the secondary winding giving the spark...!
i think for a longer spark you need to make more turns on the secondary winding,maybe 1800, but i think it cannot fit the housing so you need to use different core.. nice video brother
Three question 1. Why do you use 2 different size wires? 2. How does it help increase voltage output? 3. How do these high voltage generators use 3 rather than 2 copper coiling areas to increase volts?
2 Different size wires because the amps on the primary coil will be much higher than on the secondary (p=Volts*Amps), so the wires have to be thicker to resist that and not melt. It increases the voltage just like a regular transformer does, depending on the difference in coil turns. (more turns on the secondary, more voltage)
question: why is the electric arc so small? is it a lack of power, a lack of copper spires (no enough rounds around the E core ferrite?), or the resistor ? Very nice video.
It's a very basic 2n3055 oscillating circuit. Use two IRFz44 and feed it higher voltage and you'll get much larger arcs. Also he used fairly thick wire on the secondary, You could get a lot more turns out of a thinner wire, harder to wind though. The resistor is just used for current limiting to the base of the transistor.
No problem. The IRFZ44's are amazing though. I've tried the 2n3055's as well as larger IRFP250N's and nothing compares to the arcs I get from the IRFZ44's. I found a simple circuit that just uses the two mosfets and two resistors only. I'd share it but I've only seen it in one video. not sure where it is now. I don't think this is a great circuit because it's essentially pulsed DC which can saturate the core quickly. The ZVS drivers are better because they actually reverse direction of the flux as well as they draw very little current under no load whereas this one heats up quickly and will always draw its maximum current.
@@inductor1.77 can I use 1 d882 transistor, I have seen many videos that used irfz44n transistor and d882, the d882 result was slightly better, And I used 2 irfz44n transistor 1by 1 and at both cases my irfz44n didn't heatbut stopped working ,🙄 the source and gate pin is showing continuity 😭
i build a high voltage transformer like that.. but it will work for just only a seconds like 8 or 10 sec and hear the buzzing sound then after i get no voltage on the HV output and no buzzing soundd T_T please helppp
Is it possible to connect transformer coils in series? For example: instead of one coil with a 10:1000 ratio use a first coil with 10:100 an then make its secondary winding the primary of a second 10:100 coil. IF this should work it would mean we could use thicker wire gauge and have less heat loss (and higher wattage tolerance) with the same transformation ratio.
No, 100Kv would be 10cm arcs. You could probably get 20Kv if you used a 2 mosfet IRFZ44 driver circuit and fed it 20v, you'd also need more turns on the secondary with smaller gauge wire.
Ram shanker Verma the wire is folded in half to make the center tap, then you wrap one end 7 times one way and wrap the other end 7 times the other way
you see that's why he used the transistor and the resistor to change the dc frequency and transformators work on Pulsed DC voltage so he first Changed the 3.7V DC battery voltage to be Pulsed at transistors rated frequency and then he wired it up on transformator but this is merely high voltage that housing is too small for too many wire turns other wise great video just to demonstrate how it is done and how shell type transformators work
