Mosfet powerful voltage regulator | IRFZ44 mosfet

Works great with a 12v pc cooler fan! Thanks!

Out put kitna amper deta hai

Nice video, keep it up, thanks :)

What is the Maximum current value?

Please someone from the comment section please tell me why my IRFZ44N MOSFET is not behaving like it should. It's full written code on MOSFET is ( IRFZ44N p519d b9p0 ) when I am applying voltage from the source to the drain, then my MOSFET is in ON state and when I will apply negative or positive voltage to the Gate, then it just fully closes the circuit from the source to the drain, here the condition is that, normally my MOSFET is in ON state and when I will apply +ve or -ve voltage on the gate, it will just fully close the source to drain circuit. Please someone help me with this. I have buyed that MOSFET from a local electronic shop. Please if someone is expert in this, then please help me with the condition. 🙏🏻🙏🏻

Without a true load everything is so beautiful...

guys i recommend add 220 ohms resisistor :) thanks bro it's working

Can u only get a voltage limit of what you supply it with ?

Sir pls say what are logical mosfets and mention that few names

I hope the pot (resistor)wouldnt get smoked puff poof

It ia not working for me...i dont know why i placed 5v as input and trying to control the brightness of a led diode but the led glows very dim at full pot rotation towards the drain side...i checked the voltage it was 2v at max pot rotate...
Any fix please tell...

⁰p00p⁹ is

Is main input volt kittne diye hen? 220? 110? Ya 12 volt?

⁉️I salvage all my electronics and found one of these on a Mixstar DMG Auto Dental Impression mixer…. I don’t have a 20V power supply but close. Will a 19.5V computer charger work? I’ve been trying to make some sort of DC speed controller for a while now. What kind of potentiometer are you using? 4K? 5k? 10k? Thanks. I’m new to electronics. Btw.

220v

Thank you so much. Works well with a heat sink. 👍

Serve em 220 volte

Nice

Regultor ini bisa untuk tegangan simetrik atau ga ?

Maximum wattage please??

شكرا لك أخي الفيديو مفيد ولكن
العنوان من 3v - 50v
ولكنه غير حقيقي و في احدى الاسئلة تقول يعتمد على الاخراج لماذا لاتكون صادق انا احتاج 50v هل بالإمكان الحصول عليها أم لا

sir 12 v par 9.13 v aa rahy hai 44N par mujhy 12 v chahye bro or mujhy sapeed bi low chahye

Em qual placa de reçiclage consigo esse transistor?

Parabéns

adjustable=yes
regulated=no
why people always say that mosfet can act as regulator? if you want to get regulated output you must have regulated input to the gate pin.

You can't drive mosfet like that when load is applied perhaps one 1.5A the mosfet is very very hot

Wow,good and great idea.

Здравствуйте. Можно ли эту схему подключить после диодного моста?

Kitna Ampere load le sakte he

This deceptively simple circuit is extremely elegant for many reasons. The mosfet is being inserted in series with the positive lead. Then the pot. serves as a voltage divider
to pick off the desired gate voltage. So the mosfet is only turned on enough to create the required voltage drop to obtain whatever output voltage is desired. Since a mosfet
requires virtually almost zero gate current, a very high resistance pot. can be used. Also, if you want to use a higher input voltage, just use a mosfet that can stand more voltage.
I wanted to go from 48 volts down to around 14 volts to operate a 7809 regulator. I had an IRF 830 mosfet kicking around in the junkpile. It can do 500 volts at 4.5 amps.
I set up my experiment using a 1 megohm pot. Works perfectly! Once you find out the values of the divider, then you can substitute in fixed resistors instead of the pot.
In my case I ended up with 470k from +48v to the mosfet gate, and from there the other leg of the divider is 270k to minus side of 48 volt supply. 1/4 watt resistors are fine
because the power dissipated is only a few microwatts. Those values yield an output voltage of 14.2 volts. That output sags very little under load too.
This circuit works great for knocking down 48 volts to 14 volts to serve as the input for the 7809 regulator. 7809 regulator can only stand 35 volts max on its input.
This circuit is very useful because it is so simple and yet so elegant. Mosfets need nearly zero gate current. Also at first glance this circuit looks as if it may need
some amount of output load resistance to make the gate positive with respect to the source. But to my utter surprise, it does not need that. The open source lead
has the 14 volts on it with no load resistance. That was a very pleasant surprise which still doesn't make too much sense, but seeing is believing.
This circuit is quite stable under load. Much more stable than I would have thought. Thanks for posting this! It makes possible taking 48 volts and getting 9 volts regulated
using only 4 parts! The 14 volts from the mosfet is the unregulated input to the 7809 9 volt regulator. Then that regulator holds 9 volts rock steady up to a 1 amp. load.
At that full 9 volt current, the mosfet voltage sags only down to 11.8 volts or so. Quite amazing.

3 volt is its own consumtion, input shows 19.7and output shows max 16.7. why

Amazing

The way you connected the potentiometer the mosfet is not in use.
you can still regulate the voltage if you remove the mosfet .
This circuit is useless.

How to beat the high temperature

thanx

Q pke potensio 10 k kobong klo pke 50 k gmana pencerah an ys

Bro,if you show the circuit diagram, we will be more benefited

nice

all your load is going through your 10K pot thin tracks, which is not going to last long as soon as you will hook up any sufficient load to it. Not a good idea.

Is this actually controlling voltage or is it chopping it up and the multimeter is averageing?

Brother will that potentiometer resist 17v without burning 🙂

Potentiometer burned after some time

I havent tried it yet but it seems to be Super
Thanks a lot

Pwede po yang gawing regulator sa motorcycle?

Don't burn your mosfets like this, the drain and the gate will short if you put higher loads because of low on-state resistance in the mosfet. Buck converters are the best for high power loads and it's also very cheap

Heating problem?

Will this drive 24 volts 20 amps, thanks
