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.
Thank you for another excellent video, always the best circuits!
Mind blown on re-packing the transistor!
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
@@electronicpower1826she is only the narrator for english 😃
Who made the video i think is a slavic probably russian man 🫡
@@Norbydaner looks Like it 😂
Really nice work, dude! Great little board! 😃
The long awaited and searched video, thanks
I love the ingenuity, I did something similar with smt ics.
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 !
Love your videos and channel, need more these types of videos, thanks
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
What a great video, very impressive, I have no words to describe
That app is utterly amazing 😍
thanks for contribution my friend!
Nice circuit board with great efficiency 👍👍👍👍
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! :)
Muí bueno ok
Todo bien
Very good! Another great job,Keep up !
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.
Projetos sempre excelentes
Thank you for another excellent video
I never such a good explanation about tl494 in youtube, great explanation and can you do how to design circuit with tl494
Wow this is crazy , good job
MY FAVOURITE Channel KASYAN TV.
I need circuit diagram
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
Love your videos thanks
Love the Frankentransistor
Wow that was so cool DIY transistors!!!
In put capasitor are important.and you can add a 100n capasitor at the out put to remove spayks
Very Nice circuit and explains.
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 .
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.
Very good project 👍
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.
Great video, thanks.
Excellent video and a very good presentation. God bless you dear!
Very informative...thanks for video
Great xplain, the best.
TKS
Very good video, power supply with circuits electronics
great project
Thank you
Vey very good, thank you so much.
Just like a monster!!
can you make mppt solar charging controller!
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?
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
nice product.. please make some device to up the current of solar panels 30wp more.!!
You videos is very good, your explanation is very very good
Касьянчик, ты что ли?!))) 👍👍👍
How can we use N channel mosfet?
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.
Very informative video mam....
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
I noticed that, was going to comment.
Zener diode is a must
It is possible to use n chanel mosfet using charge-pump capacitor
Attila....new subscriber lol
Correct remark.
A clear example of Chip Surgery :) good video!
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 ?
I need special power supply 22 Volt AC and 0.5 Amperes...I can't find particular transformer for my needs...
Muy interesante, muchas gracias.
Hola mi qeridos amigo te invito ami canal si te gusta suscríbete mucha gracias desde REPÚBLICA DOMINICANA
Excellent vidéo merci
Schematic 220 ohm, you use 150 ohm?
Hola. Felicidades por el video.una pregunta. Se puede poner un toroide más grande que tenga 80uh igual en vez de poner dos?
no need pairs of BD transistors ,in this configuration TL494 can comand directly MOS FET 's.
very good video
Very nice. thanks you too much
It is possible to use n chanel mosfet using charge-pump capacitor
how to calculate E core wattage in buck or boost converter
Pcb layout is missing...pls upload...
Como darle.usos a tranformadores de este tipo
Very nice voice.
this schematic work only with >12V input ? i need to start from 8V. Is not work with 8V ? because IRF ? but with IRL ?
Me gustaria saver el diametro del cable de la bobina y como se hace el shunt
Good explain
Can you try to build diffrencial power with common components.?
how can i buy this unit from you 220v AC input and 2v-30v DC out regulated and adjustable current upto 10 Amp or more?
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?
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?
forward voltage drop
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?
Articolo molto interessante, da imitare; peccato non ci siano indicazioni per la costruzione dell'induttanza, ottimo se funziona.
Thank for the knowledge.. .if you have any idea about how to build a 12-30vdc input and an output of split type psu like +/-50vdc.. .the ampplication why its split type for thw output is for amplifier..
Yes, a split rail is useful for audio amp circuits.
this converter keeps output constant although variable input ??? la salida se mantiene constante aunque la entrada varie ???
what metal current limiting resistor 0,025R
Can you make 12 -40 volt input and 59.10 volt 2 amps output
thanks 😘☺️
can u provide the arduino based lcr meter
Is there a way to make this circuit higher voltage input.? 50volts.
Through the actual production, when the input voltage above 27 v, output voltage is close to the output voltage, power tube will be destroyed. Test conditions for no-load cases, could you tell me what is the cause, thank you.
Hi, can I short-ciruit The leads at the out to adjust my desired value of curren?
Yes, No Word To Say For Your Excellance,
it is a perfect working
also i made this
and create some of changes
for protact high voltage from input
output side make a fix
voltage with register and zener and fix amp for charge the battery like a mppt and put one more protaction for cut the battery current from 10% charge amps to 1% when battery voltage rise 14.2 till 14.4 charge with like 0.4 amps
i have no any word to say about your expiriance
you always make perfect circute
with all of calculation and risk fres
god bless dear
my last feedback for you
circute a buck convert a voltage from 15 to 90 volt
with 10 amp to 50 amp
and protaction of high and low side
with lighting protaction
revers polarity protaction
and display it with i2c
input support up to 700 watt
low side outside voltage fix
14.4 and 50 amps and it 98% efficiancy
support no west energy.
in 700 watt minus 2% energy lost max 20 watt of pcb heat
and 10 to 15 watt lost of cabble resistance
finaly out 45amp need
45x14.4(out)=648 watt for dirext use home load with 750watt pure sine wave inverter
200 amps battery
charge on day sun time in 9 hour by 20amps
thankes
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
At 1:52, what about the TL494 pin no:3 (feedback)?
Hi Sir, can the circuit of P-channel change to N-channel ? should be change /add circuit ? thanks
Thanks
You had me at hacking the P channel lol
Nice!!!
First like from tamilnadu 😀👍
👌👍
for example 40v what variable
Hello! I have made this circuit according to the diagram, but I can only adjust the output voltage in the range of 2-13vdc while the input voltage is 24vdc. Please show me why?
Pls can u provide me the circuit??
In this video there is a Chinese type power supply similar to the baku 1502 but you can see an LCD display inside... What modification did you make? What circuit is inside? schematics of this Thank you
and why can not used feedback pin (3 no pin of tl494) ? explaine about DTC (pin no 4 of tl494)...
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?
I have build this circuit but this circuit diagram does not work until you replace R7 (220R) to R9 (1K) and also completely remove R8 (220R) than it works great
I made the circuit but it doesn't adjust the voltage and amperes. Can you help me
Thank you. Those changes made my circuit work.
@@victorribeiro2304 can you help me
@@ugurozsoy8001 what's wrong?
@@victorribeiro2304 I did the circuit exactly but it did not work. I cannot control the voltage and amperage.
Nice video🙂👍, i want to ask. Can i use toroid value above 80uH? Like 100 uH?
I have made this and every parts inclouding voltage and cureent setting working fine
But short circuit protection dident work
By the way i install 0.05 shunt
So why short circuit protection wont work???
Can you make with CC Constant Current - CV Constant Voltage please
This is cc cv
Hi, I have built the circuit but I am having trouble with voltage adjustment, I am trying to use a 5k trim pot and it is producing strange results and no results when the 1k resistor is added ad shown in the circuit.
Can you please help me?
