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?
@@محمدسكري-ث1ش 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
You have the same video bro 😅
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
I tried it and it worked really well, thank you.
Really ?
3:05 using electric screwdriver as manual is legend 🤣
Do you have the inductance value ?
Very nice video!
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.
Wow I am gonna try it now thank you very very much
Amazing work! Thanks for share it
Great, need to try this while there is still an inverter🥰🙏👍
😍
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
Very useful video 😃😃😃
Thanks
الف شكر صديقي فيك تعطيني فيديو اوضح عن طريقه التوصيل
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
thanks for share this useful video..
Thanks
@@PhdHung where can i found the stuff like that
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
Why not adjust the feedback for the fans operation?
Thank you
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.
What if you use 2 mylar capacitors and 1 transformer inductor. please answer

عمل عظيم 👍شكرا لك
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
awesome
🙏
Can this same LC filter take a load of 600 watts ?
No 😢
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
Where does humming sound from ballast chock or else ?
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...
Great job 👏
Perfect.
Thanks bro
Very well!
Merhaba.Bende tepe 1000 watt sürekli 650watt ups var ve modifiye sinüs.Sizin yaptığınız gibi yapsam aynı parçaları kullanarak olurmu ?Elinize sağlık video için 🙏
Interesting I got a ballast left I been stripping em for the wire lol
help me please i did as you said but i can't lower the output voltage. i have a TBE 500W inverter.
thats crazy..easy..👍
Bro. can I convert 10000 watt nomal inverter into sine wave using an inductor & capacitor by this method?
Check waveform at no load also
What would you expect ?
I've got 7kw vfd n would love to have pure sine wave or modified ! Pls let me know ..
How many uf is the capacitor?
4.7uf
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..
Ballast how many watts
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
sir, the neon ballast you are using has a neon tl how many watts?
40W bro
very good
Thanks
Thanks
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 ?
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
WOW! It's really tube choke work?
fluorescent ballast
would be interesting to see the absolute garbage efficiency and high idle current.
you have not mention the capcity of inductor in wattage??
40 watt
If the inverter is 1000 watts, it will change the capacitor and inductors
What?
Can i do the same with 1500w ?
trik sangat menarik tuan apakah bisa diaplikasikan ke ups?
شكرا صديق فيك تعطيني فيديو اوضح عن طريقه شالتوصيل شكرا جزيلا
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?
Can i use a normal inductor
Use iron core inductors
what is iron core inductor??
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 ..
GOOD
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.
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 ?
thanks bro how to use more than 40 w
what if I use 1000 watt inverter, is it still using the same component? or should I add more inductor and capacitor?
yes
@@PhdHung Hi, kindly clarify you answered for first question or second question. Thank you for your understanding.
@@kamranahmed4602 yes,still waiting the answer
Please @Homemade 102
Yes, you can. But for higher loads I would use a higher amperage coil. For 1000 watts I would use for 120v 🇺🇸 8 or higher amp coil. For 220v use 5 or higher amp coil. It all depends on output your inverter can put out. Hope this helps.
make a zvs driver please.
Great job ! power supply basics.
yes
كم هيا الصابورة 40واط ام 20واط
1000w load k video banao
Can i use an inductor and capacitor for iron core square wave ups???
i think ok
👏👏👏👍
Yang perlu diganti apa aja ya ,?
Sir kitne ka hai uska link bhejdo
Brother, what will be inductor value
~ 10mH
@@PhdHung brother, if you have time then make video for making such inductor
Place plz plz sir
if i do this the output transistors will heat up please help me
This is bad idea. Because: You forgot to show the power lost on the inductor.
Untuk brapa watt kalau mempergunakan trapo ballast neon...
Ballasts use 1mm copper wire with a resistance of 15 ohms. I think it can work at 500W. Wastes about 5% of energy.
Ok thanks👌👌👌
@@PhdHung how many henry
A light bulb.. 🤨 put a proper load on the bloody thing..
he does 6:49, given the brand of the inverter and its so claimed "300w" he's likely near the limit of the real power it can offer with the 150w load in 6:49
useful thanks. I guess the key is knowing how to adjust the feedback trimpot on different inverters
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
You can buy a AC power wave filter on Amazon.uxcell model....30 amps ..less then $30..then modify as needed .
#Awesometech , how much power after using ballast trafo ? please
Brother if i use (100 watt Tube light ballast) on 1000 watt inverter then how many watts i can get from this setup?
The connection you did cannot see clearly..
NOT 60HZ? ITS ONLY 54HZ BUT FURE SINE WAVE
Very good 👏
0.
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
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
What oscilloscope are you using? Can you share a model?
here bro th-cam.com/video/WkCN3XpgsfU/w-d-xo.html
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.
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
I want to convert my 2000w to sine wave what do I need to add to it.
Nice one boss
Thanks
if i do this the output transistors will heat up please help me
Some inverter fish shocker convert
could I performance it at power inverter 3000 watt ?
square wave convert to sine wave
Thank you so much. This is awesome
Can I use pulse round inductor?
