EXCELLENT INFORMATION. Very good Presentation. Thanks A LOT.

[@adelal-ramahi1890]

Great work. Thanks for sharing your work and experience. It is highly appreciated.

[@LongTechnical]

Thank you so much

[@electronic7979]

Very good 👏

[@abdulhai2201]

Your design very nice tl494 operating frequency

[@LongTechnical]

Thank bro

Nice project Bro 👍🏻

Creative idea, thanks for sharing, like it :)

Why you put 0.2mm clearance in transformer core ? And two calculate the clearance size

[@mosfettech2141]

First time seen that , voltage is increased when connected to load 😂. Btw nice power supply 😃

Feedback

[@abuhasan4079]

self oscillating smps and gacun smps who are best for audio amplifier?

[@LongTechnical]

Both of them are Ok

[@AytacKORKMAZ604]

Thanks for your and author's effort. It is really great work. I want to ask you, all the test were completed? Especially for the feedback. When it was loaded, the output voltage was increasing. Are there any update about this? Or any other problem-ish situations. Thank you again!

[@hosseiny1973]

Full load test plz...

[@devinhalim8228]

Nice project. I can't find any STPS2L40u diode in my local electronic stores. Can I replace it with any other diode? As I noticed that in your PCB, you're using glass diode (1n4148 or 1n60?) as STPS2L40U.

[@necbd8893]

you can use u5401_u5408

[@style9723]

@@necbd8893 No you can't! It must be a diode that has a forward voltage drop of 0.3V !!!! TL494 is at risk of destruction!

the program for transformator can't open

[@MrFlexxip]

very nice

[@LongTechnical]

Thank bro

[@mehdad.askari]

What did you use instead of dsek60-06a?

[@klsonidhanla]

Very nice power supply.👌 What is the core material?

[@LongTechnical]

PC 40 bro

Wy air gape need in transformer serms it's a half bridge topology circuit. can you please explain?

[@Abcd-i8q3u]

Make a vedio on diy arc welding inverter

[@viettiepx2]

Awesome, and I guess you are Vietnamese?

[@ErrolAnglin-zz2kz]

Trying to build this PSU for some time now, I get oscillation from the IRF630 any idea .

[@divyansh5842]

It’s not a flyback smps so why there’s an air gap ??? Btw amazing video 👍🏻👍🏻😍😍

[@LongTechnical]

Forward smps bro

[@gicelectronics]

Same question in my mind

[@style9723]

@@gicelectronics This is forward topolgy that needs a gap.

[@mansjacobsson5823]

Hello! Just a question. I'm a total beginner at this, but in your parts list, you have STPS2L40U listed. And in your pcb it is marked as a trough-hole component, and I can only find it as a smd. Is that right? Otherwise, thank you for sharing😀

[@LongTechnical]

Yes Bro

[@LongTechnical]

Just same a value is OK

[@ErrolAnglin-zz2kz]

Great Job , Have you any spare PCB i can purchase from you

[@Rofiul_Islam]

Voltage was set to 12.5V, after connecting load voltage increased to 12.8V, why?

[@LongTechnical]

I try to fix it. Maybe the feekback not so good

[@style9723]

@@LongTechnical This is because the output inductor is too small, use a choke as instructed.

I have issues with my circuit ..would u help me I hv designed half bridge topology based smps .. i already implemented dead time in two gate input Bt when I check the input of primary of transformer then dead time does not present And if I reduced the duty cycle of gate .still transformer primary still gives 50% squre out with no dead time ..will u help me ..thank u very much
