As 3 guys from Russia commented (They are absolutely right) , the step down gizmo is not necessary and with 60A output the contraption will turn into a mini oven
There is a voltage drop across the MOSFET 2.4 to 5V. And the plates in the MOSFET will generate heat when subjected to heavy loading. Therefore, you should use 100% PWM converter rather than mix old technology into it. which is not a better result.
he is using voltage into the mosfet gates which is a bad way to do this, and there is no real voltage regulation from the output of the mosfets back to the regulator so the real output is unregulated and will vary with load, this whole design is bad
не делайте так. это ужастная идея. транзисторы в линейном режиме еще и без уравнивания потенциала на гейтах. обратной связи нет а значит о стабилизации можно забыть. на 60 амперах это будет печка на 2 минуты работы (после просто лопнут транзисторы)

В данном варианте тоже нет стабилизации! Импульсный преобразователь имеет, но прилепленный полевик нет! В результате, на выходе, зависимо от нагрузки напряжение будет падать или подниматься, ведь обратной связи, с выхода полевика на схему нет. Для полевика нужен огромный радиатор, поскольку он работать будет в линейном режиме. Еще если на выходе импульсного преобразователя окажется больше 20 вольт, то полевик пробьёт!!! Не говоря уже об остальном, то что первая часть схемы импульсная и на выходе скачки напряжения, что будет отражатся на работе полевого транзистора. Короче, это полное г...о! Если уж очправильноень хочется линейную схему стабилизатора собрать, то найдите в интернете "параметрический стабилизатор" это будет !
I did a test on the lm2596 and added 4 npn transistors and oar resistors, they used a heater on the load, used two 24v input batteries, I got 13 amps at the output without any heating of the lm2596, I didn't have a stronger load, it could draw up to 20 amps.
very good, is this method applicable for XL4016 step down, please confirm, and if possible, how to make it, is it the same way to make it as in this video, thank you if I can be responded to.
In your experiment, the voltage was changing with the load change, so what was the role of the step down circuit in the middle? Instead of the step down circuit, an intermediate transistor and a potentiometer could be used to control the current of the base transistors.
rip out the inductor. drive the mosfets from pin 2. rewire the mosfets for switching drain to source which is grounded with load resistor. load is taken from source to ground. this circuit will work perfect

I tried charging a battery with it and sadly it didn't My solar box charger spoilt so I m looking for cheap n simple alternative to atleast limit the PV output I need help
From video it appears that this technique has low current stability at load. When you adjust the output voltage at 13v and connect 21watts load, lamp glow a little. For full brightness you increased the voltage which not shown in video. When you connect 4 lamps, you again readjust the voltage. Scheme seems to be good but voltage regulation from no load to full load required to be improved.
by feeding a variable voltage into the gate of an N channel mosfet, you have turned an efficient dc-dc regulator into a linear one with poor regulation. because the N channel fet is on the high side, the load is going to pull down the source voltage, increasing the VGS, increasing its conductance and it will balance out somewhere, but the load regulation is going to be poor as it will be a function of load and RdsOn at various gate to source voltages. you are much better off using an LM317 with a parallel pass mosfet, but it is still a linear circuit. not only is the LM317 cheap as chips, but the LM317 will actually lend negative feedback of the output votlage where in this circuit the only crude regulation is provided by the mosfets VGS VDS IDS relationships and the input buck converter might as well have been a voltage divider as it's own feedback circuit has no idea what the output voltage is. if your mosfet had an absolutely ideal turn-on curve with respect to the threshold voltage, this circuit might work, but that just isnt the case.
Hi i like you go step by step practicaly doing things WELL done. However you forgot to mention that Power supply ok only Good Idea if you gonna use powersupply for 3 or so minuts only, as Mosfets will reach Such a HIGH temperature that will start MELTING complite thing., which makes Modification dangerus and usles in practical application.
Assalamualaikum kak, izin bertanya saya punya power supply 12V ampernya 70A . Kira2 kalau menggunakan rangkaian yang sama dengan ini apakah bisa ya kak
hocam elinize sağlık.güzel bir proje diyeceğim yok ama bir sorum olacak.60 Amper her zaman lazım olmaz yani bana ama o mosfetlerin yerine daha bol bulunan ırfz 44 yada benzerleri ile 10 Amperlik olabilirmi.Birde o çıkıştaki kondansatör ilgimi çekti.Özel bir durum içinmi yada benzeri bir kondansatör yada başka mosfet kullanırsak değeri değişirmi.O modullerden bir ara yirmi tane aldım arkadaş biri sağlam çıkmadı ama benzer modullerden sağlamı var.Bir denemem lazım.Kolay gelsin.
30+30 Amper olarak kullanmak zorunda değilsin, 30 amper geçirebilen bir mosfeti 10 amper seviyesine kadar kullanmak transistörü serin tutar, devrenin ömrünü ve sağlamlığını artırır. O Capasitör ana akımı filtreliyor. Step Down regülatör ise sadece Alan Etkili Transistörün alan bacağını regüleli bir şekilde belirlemek için çalışıyor, yani ana devrede yok. Normalde Mosfeti bedavaya tetiklersin ama b urada refgülatörle tetikleyip bir miktar enerji maliyetine katlanıyorsun. Bu regülatörlerden yıllar önce ben de almıştım, hiç bir sorun yaşamadım, belki de üretimini denetlemeyen merdiven altı üretim yapan bir üreticiden almışsındır.
I'm missing something.... I think the buck IC can't hold the voltage at the output if the load is variable because the output of the buck circuit is connected to the gate of the mosfet and can't read the voltage variation at the output of the entire circuit caused by a variation of the load.
can someone advise me how to improve the buck convertor into a higher current carrying circuit without losing automatic voltage regulation. Variable output, when set, must remain at same voltage throughout 3-12V@0-10 amps. much response is appreciated
i ripped out the inductor and used pin 2 to drive the mosfets. mosfets are also configurated in the normal switching operations, and not series through as in your circuit. and i found that the voltage remained constant on load or without. mosfets do get hot and will need better cooling. almost perfect variable voltage regulation.
The voltage measured with a meter my look constant but what is actually being applied to the load is pulsed DC - a rectangular waveform. Many things will not operate properly with such a waveform or actually be instantly destroyed. You can't filter to DC with just capacitors. The original circuit is rubbish. So is yours except for certain applications.
instead of makeing a source follower, you can use the pwm signal as if at coil's in to drive a power mosfet, then drive a bigger coil, and still use the same feedback network and.. ualáh! you got a new, heavyer and efficient SM regulator
Спасибо, всё хорошо и интересные схемы у тебя! Но просьба есть, схемы подключения от руки хотя бы начертить... Thank you, everything is fine and you have interesting schemes! But there is a request, to draw connection diagrams by hand at least...

5v 60A ~ 300W ---> OUPUT OK. BUT !!! On MOSFET max power is 2x214W .IF Input is 32V and output 300Wats Then power on 2 Mostets is not possible to be more 2x214~400wats. Respectivly input voltige is not possibel be more ~12 volts . And finaly .. this aluminium radiator not possible to get more 40wat from Mostets. I recomend Swiching Power Shematics for thos Power systems !
Also I want to point out that you do not put 2 transistors in parallel even if they are the same without putting some current sense resistors in the output or in the collectors of these transistors because by manufacturer speaking they might be the same but they can draw different current because in fact they are not the same and must be sure to draw as much equal current as possible. The resistors of course must be at the same value and a lot of watts.My final thoughts are these circuits are no efficient at all because you gain from the switching but loosing heat on the transistors....so this circuit is going to be very good for the cold nights as a stove and yes I strongly agree with these people.

by feeding a variable voltage into the gate of an N channel mosfet, you have turned an efficient dc-dc regulator into a linear one with poor regulation. because the N channel fet is on the high side, the load is going to pull down the source voltage, increasing the VGS, increasing its conductance and it will balance out somewhere, but the load regulation is going to be poor as it will be a function of load and RdsOn at various gate to source voltages.
you are much better off using an LM317 with a parallel pass mosfet, but it is still a linear circuit. not only is the LM317 cheap as chips, but the LM317 will actually lend negative feedback of the output votlage where in this circuit the only crude regulation is provided by the mosfets VGS VDS IDS relationships and the input buck converter might as well have been a voltage divider as it's own feedback circuit has no idea what the output voltage is. if your mosfet had an absolutely ideal turn-on curve with respect to the threshold voltage, this circuit might work, but that just isnt the case.

can someone advise me how to improve the buck convertor into a higher current carrying circuit without losing automatic voltage regulation. Variable output, when set, must remain at same voltage throughout 3-12V@0-10 amps. much response is appreciated
Zafer bey. D3806 da kısa devre koruma var mı
Hayır yok. Girişe bir koruma diyotu bağlayarak koruma altına alabilirsiniz.
i ripped out the inductor and used pin 2 to drive the mosfets. mosfets are also configurated in the normal switching operations, and not series through as in your circuit. and i found that the voltage remained constant on load or without. mosfets do get hot and will need better cooling. almost perfect variable voltage regulation.
The voltage measured with a meter my look constant but what is actually being applied to the load is pulsed DC - a rectangular waveform. Many things will not operate properly with such a waveform or actually be instantly destroyed. You can't filter to DC with just capacitors. The original circuit is rubbish. So is yours except for certain applications.
Но он там не последовательно соединяет а паралельно
Güneş panelinden pil gurubunu şarj etmek için kullanabilirmiyim..
Evet
2 volt u 12 volt 50 amper bir booster nasıl yapılır veya ürün var mı?
instead of makeing a source follower, you can use the pwm signal as if at coil's in to drive a power mosfet, then drive a bigger coil, and still use the same feedback network and.. ualáh! you got a new, heavyer and efficient SM regulator
Эту схему можно использовать для создания полуавтомата сварочного???
Спасибо, всё хорошо и интересные схемы у тебя! Но просьба есть, схемы подключения от руки хотя бы начертить...
Thank you, everything is fine and you have interesting schemes! But there is a request, to draw connection diagrams by hand at least...
Это фэйк
@@_alay4157 нет, я собрал и знаешь, работает! Ну не 60 ампер, хотя зависит от транзистора который найдёшь. И у этого парня схемы все рабочие. Он не фейкамёт 🙂😉👍
@@misha_mikheev ну ладно, просто выглядело как-то не правдоподобно и не правильно
@@_alay4157 потому что просто... 🙂
во-во, ненавижу такие тупорылые видосы, когда ничего не об'ясняя, чот паяют, не пойми чего-куда-зачем... 🙄 схему не дают... и да, LM2596 - устаревший регулятор, т.к. он на биполярных тр-рах - греется сильно, а эта схема вааще в линейном режиме работает, греть радиатор на сотне Ватт - не наша ипостась, полная дурь плюшевая! 😲
esto también sirve carga bateria de moto?
Zafer usta emeğine sağlık mosfetlerin muadili olarak başka hangi mosfetleri kullanabiliriz
bütün N kanal mosfetleri kullanabilirsiniz
30 v verip düşük voltaj nasıl aldınız verdiniz voltaj neyse onun altında alamazsınız biliyorum
This regulator gives a bad regulation with much losses - bad construction. simply terrific
Çıkışta 3v 60 amper almam mümkün mü?
4 💡es 8 ampere
Please make with step up booster xl6009 with transistor3055
If you put 3 transistors, you get 90 amperes. Correctly? Is it possible to add current regulation to this circuit?
Нет для регулировки тока нужна обратная связь, т.е нужны операционные усилители
fcomo aumentar fonte chaveada aumentr para 14,5 v de 30a 12v?
5v 60A ~ 300W ---> OUPUT OK. BUT !!! On MOSFET max power is 2x214W .IF Input is 32V and output 300Wats Then power on 2 Mostets is not possible to be more 2x214~400wats. Respectivly input voltige is not possibel be more ~12 volts . And finaly .. this aluminium radiator not possible to get more 40wat from Mostets. I recomend Swiching Power Shematics for thos Power systems !
amigo posso usar no lugar do IRFP250 o IRFZ44N ?
hi , how i make short circuit protection for this module?
Sir 21W x4 44W only?
12V 3A = 36W is original
Do you test with 300/400W bulb?
12V x 30A = 360W
Also I want to point out that you do not put 2 transistors in parallel even if they are the same without putting some current sense resistors in the output or in the collectors of these transistors because by manufacturer speaking they might be the same but they can draw different current because in fact they are not the same and must be sure to draw as much equal current as possible. The resistors of course must be at the same value and a lot of watts.My final thoughts are these circuits are no efficient at all because you gain from the switching but loosing heat on the transistors....so this circuit is going to be very good for the cold nights as a stove and yes I strongly agree with these people.
