Very simple and clear guide sir..

Error 404.. upload the files again please!

Hello! This is a great tutorial. I am even more impressed by the PCB quality and the copper traces have come out so well. Can you share the method by which you made the PCB? Will be of great help. Thanks!

Top, muito bom

Can this circuit be used for a lab bench power supply. Cause its amazing I would love to see it been built in smps projects.

Mantap sekali..❤❤❤

very good!!! tanks for download.

The circuit topology is a boost converter

Nice one sir

You would get more subscribers if you gave a bit more information on the coil and the input and output wire in diagram

Good job. 🖒🖒🖒

Please Sir how do you connect it to ac power supply source? At 30v will the current be 10 amps? How to increase current to 20amps?

Nice work is the output voltage on the capacitor

Great job

Muito bom

Nice 👍

Yes.👍

Good job Thanks

You are genius. Could you please make a video how to make a 12 - 14V Input Laptop Charger with fixed output of 19V and 3.5 A? Please show Input and Output terminals in the circuit drawing.

chevere!

Hello. I wish you would make a video tutorial about making trans-yodenes...then everyone could make them.

Thank you...is there any design rule as to where to use what type of Capacitor?

💯 👍

Hey can you build such a converter with the sg3525 ic. Thnx

Just use a UC3843 ic to make the boost converter .its easy and cheap.i may make one soon

chào anh thợ điện 😂

you can post the link to the pcb, I was involved in assembling a similar one using atx source transformer

I did not see in the test, the current supported. Maybe the construction only supports 2-3 A. I don't know !?

Can we giv here 19volt as input pls.?

Hello. Good time... I am disturbing from Iran... Can this circuit be used instead of the 12V battery input, using a 220AC to 18V DC transformer?... Then my next question is about the amperage of this circuit... Will this circuit help? Does it increase the flow or not....Thank you if you answer....Thank you very much

Can you please give coil specs. I don't have access to such coil of tv. Just mh and turnes and wire diameter is enough. Thanks

Mạch này ăn dòng bao nhiêu vậy bác

This project is true, the diagram is being requested and there is never a response, some who had access see it with difficulties. Too bad it looks like a good project

What is the transformer detail? And what is the minimum voltage level?

Aslamoalakum bhai he kea haal hein aap theek hein bhai ye btain me ke ager deck mein 220 pe ye supply lagani ho to us ke leay kea kar a party ha mtlb ye transformer ki jaga per use use kar a chahta hun

Hi friend, your video is wonderful, Can you please make a video of PCB engraving, the engraving is very nice. What bit did you use in achieving that please

Nice! But why pin 9 and 10 connect together?….. 9 and 10 always output for the tl494 IC… please answer me

Because in this way the single ended configuration can be obtained, with a filling factor of up to 98%. With only one output connected, you only have up to 49%. Read TL494's datasheet ...

@@velceaiulian6439 that's not the case at all. the output control is what determines where the pwm % will stop. If OUTCTRL is tied to ground you can have up to 97-98% duty cycle. But if tied to Vref the only about 45-47%. connecting E1 and E2 together won't do anything except for maybe destroying the IC

@velceaiulian6439

@@f.a3202 Because there is a "dead time" function, the signals from the output transistors never overlap, so I.C. will not be destroyed because of this. You can destroy it for any other reason, but because of the overlapping signals - NO !! I don't comment on the rest of the ones you mentioned, I have to look through the datasheet for a refresh, but the "dead time" thing is valid for any PWM controller, even the permanently single-ended ones. I have repaired and tweaked too many sources at work to be convinced that this is fundamental.

Very nice, but could have improved greatly by a voice over in the background that would have aided the understanding greatly as is evident with the background noise that the mic wasn't being used. The circuit at the end also doesn't help greatly for ex the voltage (Min&,Max) isn't mentioned. Finally in still wondering where the second put that you were twirling in the vdo...

It is easy, pin 7 and 12 of the TL494 are the input, negative and positive respectively, and the output is the positive of the 220mf capacitor with the same negative of the input

It isn't possible. The circuit as shown in the schematic is boost only. True buck-boost converters require quite complex control and and switching circuits.

It seems that the supporting files are not available as the download link leads to a 404 error dead link site

Please how much the input voltage
