Convert 24V 36V 48V 72V to 12V high current 

:D, I'm pretty lazy modifying eagle files. Please see the file list components

High mate, I need a answer as soon as possible what changes i need to do to make it for 36v or 35v instead of 12V ?? do i need to change the number of windings and zener diodes ?

Very good 👍👍 Dear brother, I have no words to appreciate you.

It was a nice and useful video. I watched with pleasure. thank you.

Thanks for such a great informative video , i just want to know for cost cutting if we use only one mosfet and one fast witching diode will it work properly

Hi bro is this high efficiency buck? I plan to build one with pulse trafo for my solar. Since i dont know how to use uc3845. Can i increase the efficiency by adding 150uh inductor to the output?

Great job !! Very useful project !! You are the best!!

You have shown 24v to 72v but u r testing in 55v? Is it work from 24v and in your diagram also mentioned 48v input. Please clear doubt.

Wow you are amazing I'm a big fun wonderful works keep it up. 🤖

What is the air gap(AL) value of this ferrite core? I will eagerly wait for your reply.

Can you give the link to get circuit diagram for this . Thank brother.

Great work quality. Question it I need more amperage on the output should I just use mosfet with higher amp rating or use thicker coil wire

Thanks, you circuit is one of the best...

Thanks for your reply sir,,,,a big fan of yours

Please tell me how was the efficiency of this design

Very good. Thanks Ad.

Good works output voltage stable to fix 12v if input voltage increase/dicreaase? or output voltage also increase/dicrease

They have become meke very useful projects👍

By any chance, have you created a graph of efficiency versus input voltage ? I like very much what you do, anyway

Nice, Cant wait to try it out

Hi, i have a 75v transformer, can i use it ?

Iie warmest congratulations for this very very interesting and safe project I will try to make it happen. I await the latest version with the control of the output current, who knows it could be made for 50A. Then I wanted to ask if this circuit is good for powering electronic circuits because I don't see any inductance or capacitor in output for filtering. Well come on I'm sure the next version will be TOP. Congratulations again and to the next video. 😉😉

Hi, what did you use as a 20A Fast Diode? Thank you.

How do I achieve 3-5A in this circuit ?

for 72v oor more, how many changes i have to do?

This can 24V 20A with trafo EER28?

Can you make a mppt charger for 12 volt battery charging.

Your design is prety good but did you caculate the efficiency off the circuit ?

Will it work like mppt??

ola´gostaria de informar , quase todos os arquivos que estou baixando estão corrompidos o que sera

Lanjut Om 👍

Chỉnh dc dòng nữa là ngon luôn ad ơi !

good one Now We have need a good solar charger controller circuit. All Market produce (MPPT controller) not charging properly.

When will you publish updated version, it is one of best video. One question please does variation in input voltage (like 40 instead of 55 as a fluctuation) will make variation on output or output will remain constant ?? Please answer

Please explain a 72v to 240v 50 hz 4000w squ wave inverter with stebilised supply

Grand chapeau

how to make circuit which can take both AC / DC - 20 to 253V, & convert it to 24vdc 2 amp.

Good job dude so cool and great guy

Hi im trying to build the smallest inverter with feedback on the world. But i need a very small transformer. Can you make a Video about rewinding a transformer from an phone charger? Thanks

Quanto fica uma desse amigo já montada?

Good job , add current limiting mode “ CC “ and can step down voltage to 2v.

I am confused about one connection, why have you connected battery voltage to starting of transformer secondary winding? Shouldn't it be at center point of secondary side??

Bro, which one is more high efficiency (%) using TRAFO(EER28) or Toroid cores 33mm for large currents (step down)?. thanks

Pls I need the circuit diagram for this project

Great 💝

Hi my friend... can you fix an invert-er from car alternator? from 12 v to 60v or 72v for self charging my EV car of 5 or 6 batteries.... Thank you.

simply the best

is it convert extra voltage to current (amp) if input voltage more then output voltage?

Great job sir, Is this circuit available for 60A input? I'm waiting for V2 version Thank you

Is output volt fix to 12 if input voltage up or down? Thanks

Can we get constant output if our input is variable

Super best 🙌😍

sir nice video but please make the video on design of transformer in detail.thank you.

They bro add the soft starter to avoid the sparks at input

Thank you pro

I can input 24v solar 5amp and out 12v 10amp ?

LOVE YOU SIR

Muốn điện áp đầu ra tăng lên 24v thì cần can thiệp tần số hay tăng số vòng dây của biến áp ạ?

hi,the values of resistance which you use is not same with circuit diagram.can you share the final circuit diagram.as r3 and r7can you redraw circuit again.

Good project , make a adjustable 0-36v recommended,

Hello sir it would be helpful if you say the inductance of the both coil please

Serious question: can a e-bike running 36v 10amp battery handle a 48v 10amp battery with no mods?

Very good video But 12 voltage to 72 voltage convert.....?

biến áp xung dây bao nhiêu chập bao nhiêu vòng vậy ad ơi , cả sơ và thứ cấp nhé

Can you made again this module ?, i want to buy you product.how much its cost i pay

Very informative.can you give information of transformer bax you used datasheet of that or turns ratio.

Cc cv output?

I am follow yours interesting videos about inverters. I am interest to know the a circuit diagram for my amplifier... 12vDC input from battery and output is 33-0-33 v DC WITH 20 AMP. INCLUDES OVER, under voltage protection and constant voltage and amps output. Plz give me any circuit diagram with transformer makibg. Or any assembled kit available from you... Cost please...

please make dc to dc. from 12v 5a and above until the 12v lamp breaks or turns off

Sir, can it produce 40 volt 3 amphere to 12 volt 10 amphere?? Please reply...

Congratulation. If out Will 24v How Will make ?

nice

can you send me this circuit?

Sir which paper u use for toner transfer

Giả sử dùng mấy con công suất như 100A/90V thì dùng tải có tăng lên đc ko

Most of the video is watching assembly. No current indication at the end though it looks like a 55w headlamp bulb which is only 5A, not sure if that qualifies as 'high current'? As you're stepping down the voltage I'm not sure why a transformer is being used, unless isolation is required otherwise a simpler buck converter would have been more appropriate, surely?

can you make a video about eagle pcb designing

This is a great job, but you did not show the number of turns for the second side winding, because the first side was 6+6, and the other side is which turns. Thanks

Pls do a tutorial on how to coil transformer for inverter to any wattage

Nice

Tại minh koa xem va làm theo mấy clip trước cua bạn ma n hay bị nóg một bên fet z bạn có thể giúp minh được k

Hi. How to get 5A 10A .. smaller size. Space?

Where to buy from pakistan

is there an option to buy this transformer?

This video does not explain the principle, so I will try to explain one: This is NOT a buck converter, there is no inductor here. This is using Push-Pull Half Bridge topology using IC SG3525 that is widely available. This IC responsibles for generating Inverting and Non-inverting alternating PWM output for those two MOSFETs on heatsink. The two MOSFETs responsible for delivering the "push & pull" current for in the transformer. The transformer is using turn ratio of 0.375. Using transformer at "full duty cycle" the output voltage is input voltage times 0.375. For example, if the input is 72V then the output will be around ~26V (this is if both the MOSFETs have ~50% duty cycle). The output is then put on feedback into the inverting pin No. 2 of the IC. The duty cycle adjustment (shown in oscilloscope in this video) is only for one channel while the other channel is kept near 50% duty cycle. If the input is 72V with the "full operating" you get output of ~26V but if the duty cycle of one channel is reduced to around 23% instead of 50% of it then you get roughly 12V in output. The blue mini-trimpod that you see is for this duty cycle adjustment. By the look of the MOSFET chosen IRF512, this can only handle at maximum 8A (4A for each MOSFET). Ideally this should only be used for 5A or less continuously and with additional fan. Based on the transformer ratio 0.375 the minimum input voltage should be 1/0.375 x 12 = 32V. Input for lower than 32V will not be able to reach 12V output (it will output less). Note that there is a difference in winding of the transformer. The push-pull topology is using transformer winding that is slightly different than the typical transformer. And unfortunately it is not shown in the video. Note that there are THREE terminals on push-pull in primary side of transformer and are connected to one to the Anode and two to the Drain of each of the MOSFET. The output winding is also complex and the video does not show it properly. So I think if you are beginner or don't have experience in making push-pull transformer, you will find it is near impossible to create this converter by just looking at the video and schematic because of this transformer winding issue that this video does not give enough detail. If you are beginner I suggest you just make a simple BUCK converter first, if you need a buck converter that can go up to 100V then you just need to separate two buck converters in series: a buck that convert 60-100V to say 35V, then step it down again to 12V.

Can I use this in battery charger by solar panel

is a 12v to 14v converter possible?

Please what is the size of the transformer use it here?

Where high current test ? only 70W lamp load = ?

if input 100V then it work?
