- Simple voltage controller DIY, make adjustable voltage regulator using MOSFET. ( how to make adjustable voltage regulator using MOSFET )
This circuit can provide 100V, and 50A DC as maximum INPUT. It is adjustable from 0V to 100V DC. This is a very good Circuit and you can apply a solar charge controller. But use a large heat sink. good luck to you.
Components used in this project:-
1. Irfz44 mosfet x4
2. 47K potentiometer
3. 10A diode
4. 470-ohm Resistor
5. 10K

Hi bro, this is probably one of the cleanest projects around, good job! May i know what is the max current on input? I am looking for something to use with an old server psu @12v 2500w approx 200amps. your suggestion would greatly be appreciated.
سلام استاد
استاد ایا ورودی توان DC ما باید ۲۵۰۰ وات باشه
وایا با۶۰ ولت ۵۰ امپرو میکشه اگر نه ولتاژ وامپرش چقدر متشکرم.
a quick display of a drawing would help
Dc 24 watt se chala sakte hai kya? Aur ye long time ke liye chalega ya nahi.
I'm halfway through the video and I'd like to say this is wonderfully soldered nice and neatly done good job
And to mention I have built something similar a voltage regulator using an LM317T instead of the 4 pieces that you use. And it worked only 1 lm317t
Thank you very much!
Congratulations - by mounting your MOSFETs on top of the ring mounts, and not using any heatsink compound, you've reduced the power-handling abilities of the MOSFETs by about 60 to 70%. And if you use a power supply of more than about 20 volts, it will be possible to destroy the MOSFETs if you turn the pot all the way up. If you attempt to use this setup for higher currents, you will probably overheat the transistors if you try to put out high currents at low voltages with a high input voltage. Your heatsink is entirely inadequate for the voltages and currents which you claim will work.
thank your advice.
Are those eye ring terms for external positive battery inputs??? Seems very likely & reasonably sound schematic, 'cept the over heating / not adequate for high current issues??? Can you elaborate on a high current build for say 12v-24vdc input TO 48v-120vdc high current 50a output
@@readytorvdude1224 You cannot possibly get more voltage out than you put in. And if you somehow have 24 Vdc in and 120Vdc/50 A out, you'll need 250 amps in.
I cannot "elaborate" on a fantasy. Even something like 24 volts in/12 volts out @50 amps cannot work with those puny wires.
@@wirebrushproductions1001 thanks for replying.
I'm trying to harness the alternator B+ amperage out (2ga awg) into DC/DC boost converters; (12v/150A output thru the boost modules (2 in parallel) to convert into 24v or 36v(30A 1500W max) outputs into a MPPT solar charge controller at PV INPUT. Is this practical??? Wouldn't the lower voltage at PV INPUT ALLOW FOR HIGHER AMP INPUT THERE?
@@readytorvdude1224 "Is this practical?"
No. Not only no, but Hell no. The wiring shown is completely inadequate to handle the currents you are trying for.
But hey, don't listen to some stranger on the internet who hasn't made a video. The parts are cheap. Build one channel and give it a try. Watch it burn up with your own eyes.
Did you know that transistors actually run on magic? It's a trade secret that at the center of each package is a pocket of Magic Smoke, which actually makes the transistor work. The proof of this is the fact that if you let the Magic Smoke out, the part will stop working. Build your own copy of this circuit and prove it for yourself.
I'm watching from Russia.
Well done author! Respect!
Made simply and reliably!
But, there should always be a scheme! Preferably posted separately or in the video itself, at least for 4-5 seconds.
Then it will be considered a full-time job, and this is already professional and high-quality!
And you will want to watch something else on this channel!

Смотрю из России.
Автор молодец! Респект!
Сделано просто и надёжно!
Но, всегда должна быть схема! Желательно отдельно выложенная или в самом ролике, хотя бы на 4-5 секунд.
Тогда это будет считаться полной работой, а это уже профессионально и качественно!
И захочется ещё что-то смотреть на этом канале!
thank you and welcome.
Debes hacer eso mismo, pero estabilizado, entonces es que queda bueno.
This is not a power supply, this is a radiator 🔥
This is Voltage Regulator 😅
Radiator and stupidity of the year.
just remove the diode, and no more voltage regulator.
🗿
@@RecehDIY you are right the diode prevent mosfet from re-back hi voltage
what was the reason for using the mounting hardware behind the screws if they are all being screwed down to the same heatsink?
my heat sink is aluminum. but not going current. this material problem.
Why the metal parts of the mosfets not touching the heatsink and no heat compound applied?.
So why did you use a heatsink after all?🤔
But......thanks for the upload.

What is the maximum output amphere(A) ,will it used for spot welding

This is NOT a voltage REGULATOR but just a variable resistor devider. On top of that IRF44 is a SWITCHING transistor NOT really Suited for analog applications.
음... 출력전류는 좋을지몰라도 부하의 변동에 출력전압이 안정적이지 못할듯하네요.
모터 소리로 봐서도 전압변동이 느껴지네요.
그래 네가 맞아
@@homemade_101감사합니다. 영상 잘 보고 있습니다.

Doesn’t the diode prevent the Rgs pull-down resistor from functioning?
The Rgs resistor is meant to connect Gate to Ground, but in this case the diode is blocking the ‘gate capacitor’ drain.
Theoretically, the potentiometer is acting as Rgs anyway (depending on its position) but it’s not a reliable pull-down resistor due to its variable nature. I assume that’s why the other resistor was added, however the diode appears to make it redundant?
Yes, It is no need. but it has used an motor back emf blocker.
Why do you use insulated screws? you are using conductive ring terminal
nathing
just exactly work well as you are showing but why don't you make it with easy PWM ?
Just experiment bro.
Necesito hacer un regulador de voltaje de 50 voltios y 3 amperes se podria con este tipo de circuito?

same to you. good luck
I really enjoyed this video
thank you bro
I've already tried this using even more bigger heatsink but it get damn hot when testing a Car Headlamp. But for 775 DC motor, it's ok. So, it's not 50amps.
Try this one : ua-cam.com/video/CK0MXyzSEPo/v-deo.htmlsi=gGxJLo9Md1MJHbgz
could it be the motor turning off on with the commutaion which means the mosfets gates are getting turned off and on fast thus will be cooler. While the straight out resistance load of the bulbs will mean the mos gates are on boarder line off / on which is what generates the heat. Good if you can introduce a pulsed circuit with input caps to store the incoming power when pulsing mosfet is off {to use that solar power moment the mosfet is switched on} and have that above circuit using only one mosfet to control gate threshold trigger voltage of pulsed mosfet. But what do I know, Im here because I blow mosfets and need a decent regulator. Like the joker says "If you want anything done properly - youve got to do it yourself"
Mosfets get hot really fast if gate not on properly - so much so - im surprised some {V8 type lawn mower yank hasnt put a heap of mosfets together to make a smart ass hot plate for cooking eggs - i wonder if its more efficient then an element}
I think just 2 mosfets can also controll this motor...
yes
thanks for your teach
Welcome bro 😇
Bro iss circuit se 12.6 volt lithium battery change kar sakte hai constant voltage and constant current ke sath
yes but not auto cut off
@@homemade_101 ok thanks you
What is the point of using srew plastic isolator when you put under cable conector? So in this point is useless.
yes, it is not needed now.
Kindly I ask you can use thermal paste under the mosfate and use inductor at output if yes what is the value best regards
are you need use inductor ?? why ?
good job looks very clean. how did you strip that blue wire like that? 0:51 or did you use heat shrink wrap???
yes.
@homemade_101 what ?dont just say yes. your answer is not clear. it doesnt look like its shrink wrapped it looks like a silicon wire. did u use wire stripper.
@@wunderbar-q6y No idea what he did but cutting a length of wire, removing insulation from the end and making subsequent cuts in the insulation (not the wire itself) and separating by hand to fit what you need is the easiest way.
@agentorange3774 yeah that seems to be the solution
Zabardast informatry video.. thanks
Enjoy
IRF z44 is heated on 4 ampair current and load 4v volt
🤔
أستخدم 3206
Very good❤
WELCOME
Is the center pin of the mosfet grounded to the heat sink ?
yes i
3:22 is that diode there for some regulation or just reverse polarity protection?
yes.
You can just play with it without a load, look at the beauty!
If I did this, then between the potentiometer and the gates of the transistors I would put a TL431. The output voltage in this case would be ideally stabilized.
😕
The mounting procedure is wrong, please revise it according to the good habit.
Is anything showing on the 3digit led? I can't see anything on it. What was it's purpose?
50HZ not seen camera
Bohat acha gift Dil sy dia ha inho ne

Would I fry this circuit if I used my 58V lawn mower battery? (I want 18V output.).
Looked further at video, answers my question as YES.
@@weatherwash763 yes
hi! why 50A max if each mosfet load 49A? x4, total 196A. what I need to more current? thanks
This is connect parallel. So out 50A normally
why using 4 o them when we can us only one?
Hi, it can replace rheostat 300W to adjust 0-32v?

My transformer is 12 or 24 volts AC. Can I use that? Thank you
yes but after dc
CS150N03 and IRFZ44n which is better ??
I have 3 piece CS150N03 which I collect from UPS circuit .
Now I want to make this voltage regulator using this CS150N03 .
how about it ??
Try. I think it is good
I made it.
It works but there is a issue.
show wrong voltage . voltmeter show 4 volt but when we connect 4 volt led then it will no works.but if I give 6+ voltage then it will works . so is is impossible to get accurate measurement .

thank you lot's
Welcome bro..
please, I want to buy a soldering iron from Ali express, what brand or what is the best soldering iron I can buy, thank you
Good
Me gustaría que estas pruebas las hicieran con una carga real, como el motor de ventilación de una calefacción de coche, o una serie de lámparas de incandescencia de coche, y con el correspondiente voltímetro y amperímetro a la entrada de alimentación y a la salida del regulador de potencia . También pienso que para esa potencia el disipador es claramente insuficiente para una intensidad tan importante.
عالی بود
welcome
I just see the wiring only, but it cannot drive in 100V, because IRFZ44 only 55V in datasheet...I'm confused
yes bro
What is the function of the diode, I do not understand its use
Short Circuit protection.

Please ans.
What is the point of the insulating washers of the bottom of each semiconductor is connected through the heat sink AND the ring terminals? Why not just use a regular screw and save the insulators for a project where they are needed?
Yes, you can do as you say. No problem. It is not necessary.
Why insulator - parts are directly wired.
