hi, your work is phenomenal .....but in the document, the schematic diagram is not fully clear, there are some connection left-outs.... please provide a complete schematic....
What diameter is the copper of the yellow toroid and how much is the inductance. What diameter is the copper of the yellow toroid and how much is the inductance. 
Greetings, thank you for sharing your knowledge. I do not get the primary transformer 4t. 5.mm and secondary 6t 2.mm and 37t 4.mm but in your video it appears that you turn it over I don't understand
Hi master When we wiend a chooper in clock wise in priemry witch one is input point a startone or a endone and in secndry witchone is -v point and +v point plz explain master i m very thankfull to u plz plz plz
Sir leyar bye leyar wind in this transformer...primary feedback and secondry winding..... It mean last..leyar primary..18 turn...in secondry leyar up...
That’s wrong you provide half information of bom please help me who I made it I am new and I don’t know 🤷♂️ much about that u need to provide Avery thing
No idea how I did not find you sooner, The jlcpcb competition is introducing me to soo many new makers, Love your work.
Thank friend
This smps operating frequency ? Please reply sir

Hi Long Technical, could you share with us the hardware files and tell us what program did you use to design? Thank you in advance.
Sir you are great .very good work.
great thks. what can I use ferrite bobbin? etd29?or ee28?
Thanks for sharing this. Any specs for transformers? Are they custom?
Can you make a 40A/35A psu this size or slightly bigger? That'll be very helpful to many people
I will try in the next time
@@LongTechnical 🙂
yes thank you for the video
we can input 7V - 70v ? and output 12V 5A
Very good project 👍
Thanks
Ye jo circuit board 12 volt 5 amp. Ka hai kya ye power supply mil sakta hai
Resepected sir..... Thanks for the vedio. Which transformer shall i use according to gerber??? Pls answer
I showed in video bro. Now i don't remember
In vedio pins are bent.... Which is right transformer? I ordered your gerber file pls tell me sir.......
What diameter is the copper of the yellow toroid and how much is the inductance.
What diameter is the copper of the yellow toroid and how much is the inductance.

Any core bro, it just like a filter
Great project.... absolutely superb work. Pls let know How to get 5v from this circuit.....
bro in ur video u did not shown all the coponets as diagram schematic,is the scematic is fully ok?because i am obeying the schematic diagram,ok bro?
Just tell me how to convert it for 10a and more voltage
Do I need to change the windings only or the other circuit?
What is the maximum output voltage
Can the IRF11n50 mosfet be replaced with another, can you give me the equation? Thank's....
Instead of irf11n50 what other MOSFET can be use.
Hi
I want to build this circuit.
.....
....
If I want 10 A output current, what should I do?
Greetings, thank you for sharing your knowledge. I do not get the primary transformer 4t. 5.mm and secondary 6t 2.mm and 37t 4.mm but in your video it appears that you turn it over I don't understand
Hi example : 4T 0,5mm x 5. That mean we make the lizt wire using 5 wire with 0,5mm of diametter of each wire and then winding 4 turn
@@LongTechnical but in the video you spin it more and the example is different that was my doubt
All in download file, in my description
Nice Sir 👌👌💐💐💐🙏🙏💯 Can you make a 12volt 10amps with short circuit protection & over load plz 🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳
I will pro. Happy new year
Beautiful project. Thanks man.
Thanks friends
how much does it cost, can it be delivered in india - hyderabad.
can i buy that power supply from you?
So far from you and me. I share gerber in download file. You can do it by yiurself
Can you please make a 29.9v/4-5A switching power supply for charging 24v battery. Please!!!
I will make it in the next time
@@LongTechnical Oh! Thank you.
Sir can we change current at 1-4 Amp ?
build 12v at 50A or more. please and thank you
Can you please share the schematic with me?
Nice project.
Which video editor do you use?
Adobe premier
Can you design a power supply for me ? I will pay for it. Input DC 150v to 450v . Output 12v 4A
Hi master
When we wiend a chooper in clock wise in priemry witch one is input point a startone or a endone and in secndry witchone is -v point and +v point plz explain master i m very thankfull to u plz plz plz
We have start point on second and primary. This is flyback converter, for more detai search them on google
Saludos profesor cual son las medidas del filter toroide ac y el calibre cual recomienda gracias
i just voted for u on jlcpcb😍
Bro i made this circuit
But there is a output side blinking problem
There is no overload and no voltage on 3rd pin of uc3842
Sir leyar bye leyar wind in this transformer...primary feedback and secondry winding.....
It mean last..leyar primary..18 turn...in secondry leyar up...
I saw no NTC, that limits inrush current. Please use 47 ohms one.
Yes. Thanks
Alternative of RS307 bridge rectifier and please make every video bigger than it with all details and components used in pcb .
Detail of used component on schematic. RS307 just 3A bridge diode you can use any bridge diode ex: RS507 RS607...
What i do to make this circuit of 5amps
De cuanto es la inductancia de la bobina de entrada de 220v.
tendras uno con diseño de 5Volts 30Amper
Beautiful
Thanks
I hate when some one is not talking... I think it could be more educative if you talk please because it's not easy to understand silently
How to get components
Link not work please upload right link.
Sir, please make it 48volt power supply.
I will try
How can I get 36v????
Increase number of turn in secondary
Make vdo on 5v 10 àmp
I will try
Great
Thanks
bhai hopw to adjust current
Can not adjust current
@@LongTechnical can u make this circuit for adjudtable current
I wish I can know your p.o box so I can donate you a better multimeter
Thank you so much friend but i don't have any P.O box 😭
Please make in easy way
show mor detail
Check download files
That’s wrong you provide half information of bom please help me who I made it I am new and I don’t know 🤷♂️ much about that u need to provide Avery thing
everything show in the TOP file and this project is not for beginer.
Some parts do not have names. What are those parts? can you give me your email address? can you help me?
