Make Buck Boost converter 60v 10A using TL494 - step by step

[@UtsavShah_25]

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!

[@PradipKumar-xr4kv]

Seems like a good project. Some aspects which should have been cosidered. 1 Explanation should be there. 2 Current control should be there. 3 Calculations of coil and circuit shoudl have been explained.

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

[@lawalmohammed83]

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?

[@gabriele1199]

The circuit topology is a boost converter

[@ble21nd17]

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.

[@Kyokoification]

Very simple and clear guide sir..

[@elisilva3013]

Hi! Congratulations! Excelent project ! How many Herry's in the coil Turns? Great Hug from Eli PY2EGS Brazil!

[@John_Smile]

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

[@Nomine_Pater]

Yes! But it´s cheap to try the project on a protoboard.

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

[@javiersantos4883]

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

[@Stevenson15]

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

[@Stevenson15]

I did this successfully but the mosfet overheats even with a 2 amp load

[@velceaiulian6439]

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 ...

[@f.a3202]

@@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.

[@Stevenson15]

@حيات موسوي yes

[@Sekhar_Home]

Can we giv here 19volt as input pls.?

[@Inturupter]

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

[@harunk22]

Uc3843 very bad and old! Do not and hard compensation! Tl494 very good and two opamp 👍

[@harunk22]

And output control 👍 Push-pull and single output adjust 👍

[@georgemwidima3851]

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.

[@samsonmbbanda6564]

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

[@toc_star]

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

[@herbertatencio7310]

Greetings, I can not download the diagram, help me.

[@prashanth105]

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...

[@Nomine_Pater]

We are at risk not knowing it! Not all TVs have same TRANSF. values.

[@rohitpathya4284]

Tl494 is obsolete, use SG3843 insted it has gate driver circuit inbuilt.
