Why don't you answer my request?
it seems to easy to make sine wave inverter. so why pure sine wave inverter is very much expensive than square wave inverter? pure sine wave and sine wave is not same?
@@user-rf6cl6uo8c The channel owner never answers questions and if he does, it has no content, the only purpose is to raise money with his sponsors, do not follow him, do not like him
3:05 using electric screwdriver as manual is legend 🤣
I tried it and it worked really well, thank you.
Really ?
Amazing work! Thanks for share it
Very nice. Probably not perfect but definitely an affordable workaround that should get the job done in most cases. Unlike a true sine wave inverter this one will be much more inefficient, but maybe that's a trade-off someone is willing to make to achieve a better sine wave output
I do not think it is suitable for most cases.
I guess for the no-load mode, the output voltage rises dangerously.
This circuit, however, will be a good method for cases where the load is constant
The basics is simple, the square wave is just a sine wave with lot of higher frequency harmonics and the inductor will filter out all the lower frequency while the capacitor filter out high frequency
And if the impedance of the inducor match the impedance of the capacitor, they’ll form a resonance circuit
Very good, thanks for the video.
Wow I am gonna try it now thank you very very much
useful thanks. I guess the key is knowing how to adjust the feedback trimpot on different inverters
Great job ! power supply basics.
yes
عمل عظيم 👍شكرا لك
Very good 👏
Thank you so much. This is awesome
Great, need to try this while there is still an inverter🥰🙏👍
😍
Excellent tips👍👍🙏🙏👌👌
Very useful video 😃😃😃
Thanks
continue assim..e a NASA te contrata mlk
Do you have the inductance value ?
Very nice video!
thanks for share this useful video..

Perfect.
Thanks bro
Good video! But there can be reactive power - because there flows a reactive current through the capacitor (roughly 72VAR ).It may be an extra power consuming from the accumulator.What will be if we connect in series a load , a capacitor and an inductor? Zinductor = Z capacitor on 50Hz.
i think so too, can you try it and let me know the result?
@@hungthangpham8753 I have been doing several experiments and simulations in the LTSpice software. The serial LC tank can be used with a certain active load - when the load has a big impedance (more than an inductor), - output voltage is square. The best result I achieved when I had two resonant circuits. The first serial LC circuit connects to AC phase (in series to the load). The load connects in parallel to a second parallel LC circuit.
@@hungthangpham8753 When you have a complex load (induction AC motor) - the problem can be more complex; a simple series resonant tank can be inefficient. Moreover - the pure series resonance in AC motor can leads to short circuit (and burn motor windings) - because the current limiting by the active windings resistance: you can see it when a voltage on winding is quite big.
Can you install it before the voltage feedback sense to keep voltage stabilization?
ok, wait me
@@PhdHung Still waiting
Very good idea . Can you give me the name of your oscilloscope . it's fine. Thanks
Brother if i use (100 watt Tube light ballast) on 1000 watt inverter then how many watts i can get from this setup?
Lạ quá ad nhỉ 😀😀
Lọc LC thôi mờ. Cơ mà chắc ít người thử với đo dạng sóng. Nay đo thử giật mình luôn :))))
@@PhdHung nhưng qua cái balast này có phải là cuộn dây nhiều quá ko ad
@Văn Lợi Bế người việt bác oie !
thêm khoảng 5% thôi
@Văn Lợi Bế kênh này tiếng anh ! Kênh nữa tiếng việt đó
Merhaba.Bende tepe 1000 watt sürekli 650watt ups var ve modifiye sinüs.Sizin yaptığınız gibi yapsam aynı parçaları kullanarak olurmu ?Elinize sağlık video için 🙏
You can buy a AC power wave filter on Amazon.uxcell model....30 amps ..less then $30..then modify as needed .
what power will the ballast withstand?
300W?
Super....Czyli dławik 2mH i kondensator 2,2uF Z prostokąta robią sinusa. Tylko widać, że napięcie siada mocno dość. Pozdrawiam.
Dławik ma nie 2mH a ok 1 do 3 H
Zazwyczaj tego typu stateczniki jak ten tutaj czarny mają indukcyjność ok 1 Henra
I've got 7kw vfd n would love to have pure sine wave or modified ! Pls let me know ..
Interesting I got a ballast left I been stripping em for the wire lol
Great video. How does it affect the current drawn from the battery? Fan noise is changing.
It wastes about 5% more energy.
@@PhdHung Thank's dear friend.
Where does humming sound from ballast chock or else ?
help me please i did as you said but i can't lower the output voltage. i have a TBE 500W inverter.
👍👍
Thanks
İ did all same setup. After capasitor voltage is too high 470 volts and i can not decrease voltage 220 volts. How can i decrease the voltage
#Awesometech , how much power after using ballast trafo ? please
hi, I installed the same system, my inverter is 12v 1000w, I used 20w ballast, I tried to reduce the voltage with the adjustable resistor, but the voltage did not go below 480v, is it because I did not use 40w ballast?
You didn’t take key information why the high voltage dc is to go the p channel mosfet or igbt and use a different pwm signal drive Ic to turn the mosfet on or igbt the potentiometer is use to adjust the outgoing frequency that how you turn the high down
👏👏👏👍
Sir can u make a stun fish using a ee55 transformer but without ic and also have a auto sensing fan for over heating, also have a reverse polarity and short circuit protection..
Im still gonna buy a pure sinewave inverter because this sounds too good to be true, I’ll do an experiment. Wether it works or not i am still buying the better and expensive one
What if you use 2 mylar capacitors and 1 transformer inductor. please answer

opa,top
GOOD
I know the ballas can cut 80 of current so if I want to use a 2kw inverter with the RL circuit I will need a bigger transformer
بدا المكثف بالانصهار في نهاية الفيديو شكرا اخي
Excelente video, una pregunta amigo, compre un inversor de 12 volts cc a 110 volts ac 10000watts pico pero solo salen 70 volts , tiene ajuste o está dañado? Gracias
Why not adjust the feedback for the fans operation?
if i do this the output transistors will heat up please help me
Hello, i tried this but when i plug in the capacitor, it makes lot of noise, is this causing short circuit ?
It might need a load like the lightbulb
sir, the neon ballast you are using has a neon tl how many watts?
40W bro
great project..but where i got this iron core inductor???
Old fluorescent / Mercury ballasts might be worth a look. Fluorescent upto around 100w and Mercury upto 400W. Could perhap "psarallel them up" providing they are identical.
Em mới thử a ạ, quạt chạy êm lắm, em ko có tụ 4,7uf nên e thay thành tụ bếp từ 5uf thì áp dâng quá cao lên tới 260v lận
phải chỉnh lại hồi tiếp bên trong bạn à. Của mình nó cũng dâng lên gần 260V mà.
Cái này phải mod lại, lấy mẫu điện áp phía sau phần lọc để đưa vào hồi tiếp. Hiện tại nó đang lấy mẫu phía trước cầu lọc nên nó dở hơi thế đấy hehe.
@@PhdHung em cảm ơn ạ
Sir, I'm from Indonesia, I want to ask, can I use a regular transformer like a CT transformer?
Of course. CT is a small transformer. But if frequency 50hz, use iron transformer. For high frequencies, a pulse transformer must be used. You can buy CT ZMCT103, it's very cheap.
apa itu real kawan...masalahnya sy punya yang MSW 1000 watt buat ngangkat blower 40watt saja gak kuat...
trik sangat menarik tuan apakah bisa diaplikasikan ke ups?
could I performance it at power inverter 3000 watt ?
Can this same LC filter take a load of 600 watts ?
what is iron core inductor??
Can I use pulse round inductor?
What oscilloscope are you using? Can you share a model?

Bro. can I convert 10000 watt nomal inverter into sine wave using an inductor & capacitor by this method?
WOW! It's really tube choke work?
fluorescent ballast
Sir, it uses fluorescent lamp ballast, right?
and how many watts of ballast do you use?
LOOKS LIKE 36-40WATT BY ITS SIZE
If I use 40w ballast, will the power be limited to 40w?
I want to convert my 2000w to sine wave what do I need to add to it.
شكرا صديق فيك تعطيني فيديو اوضح عن طريقه شالتوصيل شكرا جزيلا
Ballast 40 watt ?
how much of watt can handle this ballast?
Can i do the same with 1500w ?
Check waveform at no load also
What would you expect ?
thanks bro how to use more than 40 w
Ballast how many watts
you have not mention the capcity of inductor in wattage??
make a zvs driver please.
How many uf is the capacitor?
4.7uf
Quả tần số nhẩy kinh. Cục cảm anh lấy đâu vậy, thông số nó ra sao ạ
Con suoer này nó ra điện trực tiếp từ cầu H , ko lọc tụ gì cả nên nó nhiễu, con hiện sóng cũng cùi nên nó nhảy vậy đó. Cuộn cảm là chấn lưu đèn huỳnh quang ngày xưa ấy.
Some inverter fish shocker convert
Sir, after doing this efficiency increase or not?
Efficiency will decrease coz Inductance and capacitance forming LC tuned circuit will Shows reactance to the Ac which will effect our Output power in the long run.
If the inverter is 1000 watts, it will change the capacitor and inductors
What?
Không có cuộn balatte thì dừng cuộn dây nào được anh
Chắc dùng 1 cuộn dây biến áp ok đó b, nhưng mình cũng ko đo đc điện cảm của thằng chấn lưu này. Giá trị điện cảm nó lớn hơn của cái đồng hồ đo của mình.
1000w load k video banao
would be interesting to see the absolute garbage efficiency and high idle current.
Can you modify same inverter with EGS002 EG8010 module?
ok bro
@@PhdHung Good I am waiting and thanks a lot of sharing your precious work ..
Hi..
Would it work on heavy load like 3 kW or above ?
With a suitably rated inductor and hefty enough capacitor, then yes. The issue would be that the inductor would be fairly expensive unless you acquired one second hand etc.
@guyteigh3375 Would it work if one uses multiple inductors in series ?
Awesome 👏
1) will the same setup will work for APC 600va/360w ups !?
2) can we use isolation transformer instead of inductor ballast !?
I think it will work
@@PhdHung thanks !
@@PhdHung That same ballast can be used in a 2000w 12v ?? or what should I change, what power does that ballast and the capacitor ?
when i load 250w the voltage becomes low.....what can i do???
You do what is your battery ah so you use battery 100ah battery and you use more mosfet and see the voltage
