- Making 5KW transformer for sine inverter
I am building a sine inverter 5KW-48V, First, I need to build the transformer, Transformer must be big enough. I use 16 Kg toroidal iron core, Copper wire for 220V is 3.14mm2, Copper wire for primary is 12mm2. Because I use EGS002 module. I need a 28V for pre and 220V secondary. Once completed, the transformer weighs 20 Kg.

Nice , and I am the first to comment
Very good
How much meters copper wire you use on coils
Hi, can u show video how to rewind computer ups transformer secondary to 35-0-35v.
Where's we can buy iron core? Or maybe you can make another video DIY toroidal iron core?😁
Мощность и железо...
Ручная работа...
Спасибо за видео... 🙇❤️❤️❤️❤️❤️
A very interesting way to make a toroidal transformer. Well made by hand too
Nice work. Can't wait to see the no load current draw of it.
It will appear soon, waiting for me.
Really Amazing! Bro...Nice! Keep it up..God Bless you.
Thanks bro. Have a nice day
Really Amazing Bro....Nice! Keep it up ..God Bless you
The wire going to overheat at 5kw you should use 5 layer of thick wire to allow the current bigger space to flow stoping heating
can you talk about winding the secondary for a split phase? ie 48v primary and a Center Tap with 240vac between legs L1 L2 and 120vac between L1 or L2 and the Center Tap? Is this safe (compared to taking a step up transformer from the sinewave inverter and putting an autotransformer across the 240vac to create a split 120vac?
Awesome project
Thanks bro
I have to say you most certainly are not skimping on material mass. Nicely done. Am not sure but there must be an easier way to wind this transformer. Using a spool bobbin with wire on the outside sliding inside the triodial donut rubbing the wire against itself can cause problems with thinned de-electric insulation from my experience. Look forward to more great videos from you Sir. VF
Good idea, thank you.
Woow that's really very big awesome 🤟🤓
@@PhdHung great job!
i love your work man, i want to help with turning wire around the core.
maybe you can take a 3 cm thick broom rod, 20 cm (or more) long, turn on him the wire about 10 cm (more or less). i hope it will take less time
How did you choose 12mm2 for the primary please show us the calculation
Nice work
in North America, we have a single phase, split power system for residential service. Can you do a video on designing and winding a centre tapped 220/110v secondary? Great Videos! Thanks Doug
Is it really necessary to use such a big transformer for only 5kW-48V invertor? Nowadays those kinds of invertors are sold (including for solar solutions) with a lighter weight.
Well done keep it up :)
My 5kva transformer is 16kg core 114mm inner diameter 223mm outer and 80mm high, 40cm2 core running flux at 1.406T 1.25V/Turn at 50Hz has a 230V secondary 184T of 3mm diameter 7.07mm2 enameled copper wire 54m wire length and 67Watts at 21.7Amps 230V, Primary is 28.75V 23T of 2mm diameter x 30 strands = 94.25mm2 at 28.75V and 175A is 58.5Watts plus core losses being 20Watts. 145.5w loss at 5000watts out = 97% efficiency. Add a 2 % loss in the inductor and inverter mosfets brings down to 95% not too bad.
Nice. What did you use for the series inductor at that current ? Iv been wanting to wind my own but cant find the write material. Im around 100A running current.
Hey, pleased to see some people do the calculations required to make a sensible design. Some of the designs for inverters dont even make the basic calculation (w=vxa) for the overall design to see the requirements.
How did you calculate the primary wire size to be 12mm^2
Hi anh, a chập 2 dây 6 li lại, và dùng gì để bọc chúng lại vậy, là ống co nhiệt hay gì vậy

Thanks bro.
what is the awg size of your 220v coil? thank you
Cách tính số vòng dây để quấn như thế nào ad

can you explain the light bulb test for this transformer?

Nice work, do you know what gage wire and how any turns I would need if I wanted to get 50amps and 24volts from a single coil if my magnet which is n52 40mm × 90mm is spinning at 3500 rpm?
Hey , for the wire thickness you will need an area of more than 4mm2 , and this will be very hard to form into a coil if you used a single conductor so you should get many strands of thinner wire and use them in parallel, about the turns i don't really know but 3600 rpm will help you get the voltage you want l. Please take a look at my generator🙏
how can you know is a 5kw and not 3kw? Does it matter how "big" is this iron core, or is just what is easier for you to build? I imagine is easier to wind this wires on a big torroid then on a very small one, because on the big one there is more room to move your hands. But is that the reasoning for choosing such a big iron core, or it actually technically matters to be that big? And how exactly can you know upfront how big it should be if you want say 10kw or 7kw?
Yes, in the next video, I will show you how to calculate a transformer.
It will give a lot of power
Yes sure

Hello friend, I liked this transformer. I wanted you to be a video of how to do the calculations of a well-explained ferrite transformer that I still cannot calculate the ferrite ones or they are the same with those of kiero plates that help me in that, greetings from Honduras I love your content
Yes, I will do it.

Amazing dear brother. I thing first 5kw transformer winding on TH-cam. Where you use this transformer ??
I took it from a 10KVA voltage stabilizer
th-cam.com/video/cpAfI1JENtw/w-d-xo.html
Core area is 7x7, or 49; so? 49x49 is 2400 watts max for that core; ?
Or you double it, being a toroid? 2400x2~~5000 like you say
Thank you
Could have posted no-load current and efficiency at 50Hz too, good job tho
Now i am still waiting 1 month for your next video on 500 watt iron i core transformer with calcution

:D yes
apakah sudah jadi bung, work kah? saya juga mau bikin kalo memang berhasil dengan baik
Please make Tesla coil with mosfet please
Now i am still waiting 1 month for your next video on 500 watt iron i core transformer calculation
How do you calculate the required core size/cross-section? Would this size work for 10kw if I increased the wire size? Can you put two transformers in parallel?
Yes, in the next video, I will show you how to calculate a transformer. Can use 2 cores.
@@PhdHung saya menunggu itu kawan
you can stack toroid cores if needed
16kg's of silicon steel!
This is why we use high frequency PWM sinewave synthesis converters. A 5KW high frequency converter would use an EE65 ferrite core that is less than 5% of the weight of the steel core.
I think iron core inverter will be more durable. th-cam.com/video/tr4cyr2gqqo/w-d-xo.html
@@PhdHung I have also found that many high frequency inverters have questionable reliability, but it doesn't have to be like that. Many manufacturers use quite old fashioned voltage mode control inverter topologies that can't react to flux staircasing of the core, resulting in saturation and destruction of the power Mosfets. I've also seen inadequate snubbers using the wrong capacitor dielectric also resulting in self destruction. If these and other issues are addressed there's no reason they can't be very reliable.
@@rogeronslow1498 What about surge load handling capability like starting of induction motor. Do you think ferrite core transformer can handle it better than iron core?
@@rupeshpilania7409 The surge current capability of inverters is dependent more on the MOSFETS and output diodes selected and the high freq filter inductor peak flux density. The transformer will just experience a temporary thermal spike which it should easily be able to cope with.
Good Job and Thank You very very MUCH for SHARING!!
I only hope people get smarter by learning how to make their own electricity and stick it in the ASS of corporations ROBBING US BLIND!...
i understood that and i'm working on making MY OWN Electricity and Hydrogen Gas for anything and everything...
Good luck
Why do you use 12mm^2 copper wire for the primary and why do you wind for 28volts instead of 48volt
I think, RMS value of 28V is 40V. 10V is 0% in lead acid batteries and 10x4 =40V
Explain how you calculate winding turn primary and secondary with different size iron core
ratio stays the same

Where you find that iron core?
Few years ago I make the calculations for one to 120v, but can't find the core.
I took it from a 10KVA voltage stabilizer
Search eBay for "toroidal laminated core"
@@jackpatteeuw9244Bro It shows "no result found"
@@PhdHung when I search google for "10 kva voltage stabilizer" It shows many names. can you tell the name of which stabilizer you use?
@@PhdHung very much impressed, sir if could ask,can this same transformer be wound to handle 10kw sine inverter? What will be the calculations for the 10kw?? That,

No entiendo lo de usar materiales inflamables en algo que se calienta.
It is glass fabric. It doesn't burn
Need a big help, current I'm using invt 3KW inverter, which has a big transformer inside. According to my calculations, transformer draws huge amount of current during idle time as well. How to over come this without changing the current unit.
You should connect the transformer primary in series with an inductor.
@@PhdHung what's the calculation in order to get the right inductor for any inverter size???
hello sir this very good project.... sir please make video on how to make long range microphone to earnphone.i shall be very thanksfull to you. this is simple video first make this project
Todo para que prenda un foco de 60 watts !!
What is that core made of? Is irlt ferrite?
iron core
What is diffrence betmeen normal trasfarmer and round tranfarmer .and which is better?
toroidal core has a larger capacity, greater efficiency. And it does not jam electronic devices around it.
Good job make it's inverter video quick
Yes, I am building it
Thanks for you video
Does this design (O) work better than a traditional transformer shape [O]? If so, would it be worthwhile to round the edges of the iron to make the shape more like a doughnut (a true Toroid)?
yes, no
Itu yg gulungan awal 16 jg itu apa ya mas?? Plat atau apa??
Good job. However, I think that with 38.5 cm2 core cross section we will have max 2kw. Correct me if I am wrong!
1482w
Yes, but capacity depends on iron core weight. A lot of people make the same mistake as you.
1kg~125VA
@@vishwakarmaelectric_kankinara no i also understand as you think but after visiting market and experience told me 1 kg =300- 500 va
How u calculate Core Cross Section ? Where does 5.5 comes from?
that looks like a mistake, i think it should be (270-130)/2, or 7. but the error is in the side of caution
@:23 is that cotton or fibreglass ? or ?
fibreglass bro
Im watching
Where is the file schematic, Sir? Link please
It will appear soon, waiting for me.
Actually, you don't need sine wave for inductive loads.
Yes, but for now, making a sine wave inverter is easy.

Hi, can you tell me why you chose K= 35 ? did not choose 42, thanks
With high-quality cores, you don't need a large K-factor.

Why not use high frequency for a small tranformer after that you change the frequency in 50-60 hz
How much input does it take bro?Plz reply.
i use EGS002. with 48V system. need trafo 28V > 220VAC
Why do you choose k =35 and some toroidal use 42

How much gate voltage need for this inverter sir
you cant build if you have to ask this
I would like to make a request if you don't mind. Could you build a 12 KW PURE SINE WAVE INVERTER HIGH ACCURACY using only Precision Components? On one end having having a Precision Variac Variable Transformer adjustable from 0 to 240 Volts AC with adjustable Amperage say from 0 to 150 or higher Amps. On the other end would have PRECISION ADJUSTABLE DC VOLTAGE from 0 to 120 Volts or higher with a HIGH PRECISION ADJUSTABLE AMPERAGE from say o to 150 Amps or higher. Using only the best CAPACITORS, TRANSISTORS, DIODES, THERMISTOR, RESISTERS, and so on. Designing a very good Short Circuit protection System. Showing your design with clear Circuit Layout. Designing the Cooling System Using Low Voltage Fans with MINERAL OIL, FLUORINERT, HYDROFLUOROETHER or something like these within the HEAT DISSIPATION SYSTEM. With-in your design and build if you decide to take this challenge. Your design would have FOUR 110 - 120 VOLT / 20 AMPS AC outlets and TWO 220 - 240 VOLT AC / 30 - 40 AMPS outlets on the AC side. On the DC side you'll need up to EIGHT Low Voltage USB Ports for charging all modern devices. It would be great if you could put in your design a testing Station with Clear Readouts of DC Voltage and AMPS. Your design and build would have the ability to charge LEAD ACID, LITHIUM, and NICKEL METAL BATTERIES with Protection Circuits for Over Charge and Under Charge Detection and Reverse Hook Up and Short Circuit. Your design would need a Battery Balancing Circuit with Auto Cutoff and Alarm. Your Design would need to have Solar capabilities so the batteries could be charged using the SUN and Generator. It would be great if you could source all the components from Junk Found Around Your Area. This is a very large Job to take on. It will require a great deal of thought and Planing. I think it would be a great Educational Video and well worth your time, in my opinion. Yours maybe different. Please leave me your comment. If you don't mind telling me why you wouldn't consider taking it on. I hope you do take my suggestion and build this project. Thanks for the upload.
interesting
I took it from a 10KVA voltage stabilizer
You know you ask for a 5k$-15k$ project with an unresonable bad efficiency?
Nobody does this for a good reason these are custom build inverters (neutral point clamped inverter) no big unit one fits all.
If you use solar in 12KW range you should consider a HV solar System with around 500V Solar input without a transformer.
@@losttownstreet3409 Well it took you long enough to reply to my request. Thank you for your reply. I understand what you have said and your right about it being for a good reason. Can you do it using old Electronics found around your area and what about no transformer? Make it Solid State. This would test your knowledge, would it not? Again. Thanks for your reply
@@losttownstreet3409 high frequency (transformerless) inverters are very bad - useless for inductive loads (start currents of motors, compressors, etc). With low frq. inverter like this, you can get out tripple of its max. power for shorter period! These properties are impossible to achieve on HF inverters ... We run two buildings on 8kW LF one (48v DC) for 6th year now 24/7, without a single problem, not only home appliances, but also milling and turning machines, CNCs, compressor, various welding machines ... Before we burned two brand new HF - high frequency (factory made transformerless) inverters. Living Off-grid is fun if your inverter is the right one.
