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.

Мощность и железо... Ручная работа... Спасибо за видео... 🙇❤️❤️❤️❤️❤️

Nice work. Can't wait to see the no load current draw of it.

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

A very interesting way to make a toroidal transformer. Well made by hand too

Really Amazing! Bro...Nice! Keep it up..God Bless you.

Really Amazing Bro....Nice! Keep it up ..God Bless you

How did you choose 12mm2 for the primary please show us the calculation

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?

Could have posted no-load current and efficiency at 50Hz too, good job tho

Sir copper 6 kg coil lagaya hai wo kitna kw load le payega dry transformar

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 calculate the primary wire size to be 12mm^2

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 explain the light bulb test for this transformer?

Awesome project

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.

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

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.

Hi anh, a chập 2 dây 6 li lại, và dùng gì để bọc chúng lại vậy, là ống co nhiệt hay gì vậy

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?

Nice work

what is the awg size of your 220v coil? thank you

Woow that's really very big awesome 🤟🤓

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?

Where do i get the core?

verygood

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

Cách tính số vòng dây để quấn như thế nào ad

apakah sudah jadi bung, work kah? saya juga mau bikin kalo memang berhasil dengan baik

Ghar ke liye torotoid stablizer 5 kw me use kiya jata hai agar haa to kaun sa company aacha rahata hai mujhe yeh banwana tha best suggest me

Can use welding

Amazing dear brother. I thing first 5kw transformer winding on UKposts. Where you use this transformer ??

very very very very very vevery very very very very very very very very very very very very very very very very very hard work

xuyến này phần sc nếu sài 24v thì quấn bao nhiu vòng v,

What is the core area for 5kw toroidal transformer

What is the name of the white cloth you use

Well done keep it up :)

Why do you use 12mm^2 copper wire for the primary and why do you wind for 28volts instead of 48volt

nice video and creative

Top em

Nice!

What type of cloth tape did you use ?

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?

What iron do you use to make transformer cores?

why not use a switching power supply

How many watts input?

How many turns for 12v to 220v sir

I need 5 kw with battery charger and utility current option. Let me know if available

Where you find that iron core? Few years ago I make the calculations for one to 120v, but can't find the core.

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.

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

HALLO; ist der eisenkern auch selbst aufgewickelt? bitte davon auch mal ein video machen........viel erfolg und grüße.

What is that core made of? Is irlt ferrite?

It will give a lot of power

Subscribed !

What is diffrence betmeen normal trasfarmer and round tranfarmer .and which is better?

Thank you

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.

Bom dia , quanto custa um toroide de 3000 w pra 127 v

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

How much gate voltage need for this inverter sir

Explain how you calculate winding turn primary and secondary with different size iron core

Ok felicitari

Hi, can you tell me why you chose K= 35 ? did not choose 42, thanks

Itu yg gulungan awal 16 jg itu apa ya mas?? Plat atau apa??

How u calculate Core Cross Section ? Where does 5.5 comes from?

good

@:23 is that cotton or fibreglass ? or ?

Hello bro can i use 42 as coefficient?

How much input does it take bro?Plz reply.

Dây điện đỏ với xanh đó ra tiệm điện gọi như thế nào để mua nhỉ

No entiendo lo de usar materiales inflamables en algo que se calienta.

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...

Why do you choose k =35 and some toroidal use 42

It’s a Massive transformers

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)?

How many Hertz, or Khz?

Now i am still waiting 1 month for your next video on 500 watt iron i core transformer

Now i am still waiting 1 month for your next video on 500 watt iron i core transformer with calcution

Where to buy this item.

Good job. However, I think that with 38.5 cm2 core cross section we will have max 2kw. Correct me if I am wrong!

Come on now. You didn't show where and how you made your taps to the coil. You need to go back and show how your taps were made.

Please make Tesla coil with mosfet please

Dear sir, I would like to make the 5600w transformers, input 24v , 50hz, output 230v , 50Hz, How to choose the primary winding and secondary winding , turns & cage size wire?

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.

Hi sir i neet this one how much?

NIce , And I am the first to comment !!

Now i am still waiting 1 month for your next video on 500 watt iron i core transformer calculation

NIce , and I am the first to comment !!

Good job make it's inverter video quick

how do i get core ,please tel me

Thanks for you video

Why not use high frequency for a small tranformer after that you change the frequency in 50-60 hz
