Da best explanation of TL494. Simple and clear. You make hard stuff became easy stuff to explain. Broke TO220, to new part. You are awesome, man.

The long awaited and searched video, thanks

Thank you for another excellent video, always the best circuits!

I love the ingenuity, I did something similar with smt ics.

What a great video, very impressive, I have no words to describe

Great video. Recently, there are many options of good PWM controller. One of them is RT9259 which applies totem pole output state. Totem pole output can prevent voltage-pumping by complex load. Cheers from Indonesia

Great Video! This is a Buck Converter build for those of you that were looking for a Boost converter. I was looking for a Boost converter. Lol

Well.... no look at the RDSon of them when she is messuring them 0,7 Ohm! if she put there 15Amps there will be power loss almost 80 W on each tranzistor. They would burn instantly

I need circuit diagram

Love the Frankentransistor

Nice circuit board with great efficiency 👍👍👍👍

The interference ( 15:29 ) is actuality coming from the power supply itself. This is a Switch Mode Power Supply (SMPS) , they produce a lot of noise.

Really nice work, dude! Great little board! 😃

Thank you for your videos, it’s very interesting. I learn a lot with you. I encourage you to keep doing interesting videos like this !

Wow this is crazy , good job

Very good video. You explain circuit function very clearly and the visuals outlining the parts of the circuit you are describing the function and operation of is very helpful. Found that modification to the surface mount transistor very interesting too. Thank you and keep up the good work! :)

Hello boss. Pls replay.. i need that circuit. I created with the given circuit but not got sucess .my output is there but no voltage change when changing the pot. What problem pls

Superb converter

maybe I can use this schematic to turn it into an AM modulator! instead of the voltage regulating potentiometer, I do the modulation in there. the control schematic for stabilization will also be canceled!(does not have to be made!) Friendly greetings from The Netherlands! Rob.

Thanks

Very nice. thanks you too much

I have never seen somebody Hacking a MOSFET before.

nice product.. please make some device to up the current of solar panels 30wp more.!!

1.98 volt minimum,, not 0,,but i see the great explanation👍 ,,very well

Nice!!!

I built it & it works ,BUT , as he mentions it's not a bench powersupply ,it's a charger .because it is very noisy . At 3 amps output i get about 2.5 volts of ripple .

I really appreciate this supply for hobbyist, but in older days I have seen it working from 0-24v. I want you to please mention changes to make it work from 0v level rather than 2v

Thanks for your tutorials,I bought both transformer calculator programs,can you make a video for flyback converter and how to use the application,thanks .

you are a different woman and a different person and so you are so impressive.

You had me at hacking the P channel lol

Articolo molto interessante, da imitare; peccato non ci siano indicazioni per la costruzione dell'induttanza, ottimo se funziona.

thanks pro

Great stuff as usual. I just want to know how to attach an lcd display to show output values and input values auch as current and voltage.

First like from tamilnadu 😀👍

no need pairs of BD transistors ,in this configuration TL494 can comand directly MOS FET 's.

The current sensing resistor (Rx) is outside of voltage control loop! The output voltage will droop with the voltage drop on this resistor (0.375V). Output voltage will not be stabilized.

Verry good video. But could you show what transformer i schould use if i want from 230v to 28v and how much imputcurrent is required?

И тут Касьян)

nice

Thank you for the excellent Circuit. Need some help on output Transistor, can you suggest any other transistors equivalent in place of IRF4905 they are not available in our market. My transformer DC output is 37V- 6Amps after filter. I want to use this as bench power supply for my mini workstation. I am a hobbyest.

По английски стабилизатор будет regulator, не stabilizer. Вообще, над переводом еще стоило бы поработать.

can you make mppt solar charging controller!

The input voltage range is up to 30v this means that if the ic switch to the ground (pin 8,11) between G-D the tension is higher then the maximum 20v this kill the MOSFET

Correct remark.

The supply is unstable. when you show the scope waveform at 2:32 the pulses are dithering with a 10 Amp load. If you reduce the load to just a few amps it may get worse.. You cannot use the DVM to check for stability. The output could be oscillating from 0 to 10V and the DVM will show 5V. The scope is the only way and the pulses must be completely steady. In any case I give this a Thumbs UP!

Hola. Felicidades por el video.una pregunta. Se puede poner un toroide más grande que tenga 80uh igual en vez de poner dos?

good

hello.i made this circuit and seems to work but the mosfets gets too hot even with 200ma load although in the video says you dont need heat sink for about 3 amps load.i wonder what will happen with 3amps load or more.also i see comments that you must change some components with others?which is the corrent placement after all?

Muy buenos ......

Can you try to build diffrencial power with common components.?

How can we use N channel mosfet?

Would it be possible to use an electric load to control a max 24V and 30A at the output? And how many P channel mosfets would you need?

this schematic work only with >12V input ? i need to start from 8V. Is not work with 8V ? because IRF ? but with IRL ?

It is possible to use n chanel mosfet using charge-pump capacitor

You use 2 resistor 0.1 ohm 5w it mean current shunt is 0.05 ohm is that correct ? Can use any P chanel mosfet with high output amps ?

At 1:52, what about the TL494 pin no:3 (feedback)?

Hello, Thanks so much for the video. I'm wondering how could I modify the schematic to get 0-60VDC, 0-50A adjustable output? Can you help me with that?

hello thank you first .... but i do have one qustion what should i modify to let it work on 37v input and 25A current ?

this converter keeps output constant although variable input ??? la salida se mantiene constante aunque la entrada varie ???

Nice video🙂👍, i want to ask. Can i use toroid value above 80uH? Like 100 uH?

I need special power supply 22 Volt AC and 0.5 Amperes...I can't find particular transformer for my needs...

Hi, great video as always, I installed the flyback app, it works very well but I don't know exactly where to find the value of Ud. It is the maximum diode reverse voltage or the forward voltage drop?

@f.a3202

forward voltage drop

If I put transistors on P-chanel IRFP9140 100V VDS, power supply TL494 on a 33V Zener diode and a 2W 270 Ohm resistor, 220 Ohm resistors, 270 Ohm tam, capacitors on 80V, gate resistors 10 Ohm, will the converter work and will it not burn up? When you power it from Vmax 60V or 55V 6A panels and connect it to 12V charging? Also consider whether to exceed 20V VGS. Schottky diode 20A 80V. Inductor 95uH.Why, after making the above-mentioned modifications, i.e. changing the transistors to the mentioned IRFP9140, inserting a 270 Ohm resistor and a 33V 1.3W Zener diode on the TL494 power supply, replacing the 220 Ohm resistors from the diagram - I gave 270 Ohm, gate resistors instead of 4.7 Ohm, I put 10 Ohm instead I put a resistor at the 680 Ohm output at 820 Ohm. After exceeding the supply voltage of 38V at the input, an undesirable 25V appears at the output despite the regulation? What is wrong?So I have 35V and I connect it to the converter input, I set 14.5V at the output. I increase the voltage at the output and exceed 38V - suddenly the output appears 25V or more, potentiometer regulation then no longer works. What's the problem? I think that the choke changed something from 95uH to about 150uH. He should help.

Me gustaria saver el diametro del cable de la bobina y como se hace el shunt
