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
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.

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.
I enjoyed the video. Like the video above Maybe output 15A~20A Is there something that can automatically step up and down? If there is any, please send me a video.

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
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
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.
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.
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.
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.

Anahtarlamalı regülatörü lineere çevrimek tam bir verimsizlik abidesi. O modüllerin olayı zaten anahtarlamalı olması bu nedenle yüksek verimlilik sunması. Entegrenin Switch çıkışına 100 amperlik bir mosfet ekleyerek, bobini de daha kalın telli 100 amper kaldırabilen bir bobinle değiştirerek 60A alınabilir. Verimlilik de çok düşmemiş olur. Yaptığınız şeyde 12V girişten 5V 60A çıkış aldığında 420W boşa giden bir enerji olur ki bu da hiç yabana atılacak bir enerji değil. Bir 9W'lık bir led ampülün aralıksız 2 gün çalıştığında harcadığı enerjiye eşdeğer. 3W 5W falan olsa hadi, neyse.

I am writing to you today to provide some feedback on the electrical circuit testing you have showcased on your website. I have found your website's content generally informative and appreciate your willingness to share your knowledge and expertise with others. Feedback: I noticed that you tested the circuit using only four bulbs, which represent a power consumption of 84 watts (12 volts × 7 amps). In your circuit description, you mentioned that it can handle up to 60 amps. I would like to suggest conducting additional tests on the circuit using larger loads to observe how it performs under full-load conditions. Furthermore, your testing did not demonstrate how the circuit behaves when the input voltage is changed. Would it be possible to test the circuit using different input voltages (higher or lower than 12 volts) and monitor the effect on the output voltage? Benefits: These additional tests would provide valuable insights into the circuit's capabilities and limitations, which could be highly beneficial for potential users. By comprehensively testing the circuit, you will be able to present a more accurate picture of how it functions under various scenarios, assisting users in making informed decisions about its suitability for their needs. Thank you for your time and consideration. I appreciate your efforts in sharing your knowledge and expertise with others.

Muy interesante: Pero . utilizas un circuito conmutado para tener una tension estable a la salida. No pusiste el instrumento sobre la carga. basicamente es una resistencia variable en serie con la carga. deberias haber utilizado la tension de salida sobre la bobina par excitar los transistores y algun sistema de realimentacion para la tension. la eficencia del circuito en la conversion es muy mala a bajas tensiones debido a que no aprovechas los beneficios de la conmutacion de potencia.
.. en realidad el mosfet requiere tan infima corriente en el GATE, que no hay variacion de tension medible en DRAIN, contrario a lo que pasa con transistores bipolares. Un lazo de realimentacion, en una fuente conmutada de ese diseño, no se justifica, a no ser que se pretendan regulaciones de laboratorio, para lo cual existen fuentes de alimentacion dedicadas a tal proposito.

Yaptığınız şeyde 12V girişten 5V 60A çıkış aldığında 420W boşa giden bir enerji olur ki bu da hiç yabana atılacak bir enerji değil. Bir 9W'lık bir led ampülün aralıksız 2 gün çalıştığında harcadığı enerjiye eşdeğer. 3W 5W falan olsa hadi, neyse.

18 volt sarzli matkap bataryasından güç alarak, araç aküsü zayıflamış olan araca mars basmak için Bi devreye ihtiyacım var.
Yani 18 volt 12 ye düşecek ama yüksek amperide zarar görmeden araç aküsü e parelel bağlı çalışabilmesi. Zafer beyin bu devresi ise yararmi sizce
You can do it even without the step down module, its liner voltage regulation and it's not efficient way to step down voltage
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 !
Chạy áp nhỏ nóng phỏng tay. Áp lớn thì không nóng
How many volts is the input current?
استاد اگر میشه طریقه ساخت شارژر باطری موتور سیکلت وساخت ترانزیستور یا cdiموتور سیکلت را یاد بدید🌼🌹🙏سپاس از کانال خوبتون🌷🙏
Missed conversion or making soldering?
Can use this circuit with other step down module?
Nice work. i got quection, i want to make power bank for external camera flash (6v) and i make one using DC-DC Buck Converter but problem is when i trigger the flasher batterys getting hot then burn the Buck converter. is this gonna work for it or any suggestion please.
I am writing to you today to provide some feedback on the electrical circuit testing you have showcased on your website. I have found your website's content generally informative and appreciate your willingness to share your knowledge and expertise with others.
Feedback:
I noticed that you tested the circuit using only four bulbs, which represent a power consumption of 84 watts (12 volts × 7 amps). In your circuit description, you mentioned that it can handle up to 60 amps.
I would like to suggest conducting additional tests on the circuit using larger loads to observe how it performs under full-load conditions.
Furthermore, your testing did not demonstrate how the circuit behaves when the input voltage is changed. Would it be possible to test the circuit using different input voltages (higher or lower than 12 volts) and monitor the effect on the output voltage?
Benefits:
These additional tests would provide valuable insights into the circuit's capabilities and limitations, which could be highly beneficial for potential users.
By comprehensively testing the circuit, you will be able to present a more accurate picture of how it functions under various scenarios, assisting users in making informed decisions about its suitability for their needs.
Thank you for your time and consideration. I appreciate your efforts in sharing your knowledge and expertise with others.
bu devre şuan bu şekli ile tutarlı bir gerilim regülatörü olmaktan çıkmıştır (mosfet yerine npn transistör olsaydı gerilim sabit kalırdı) verim çok düşük bu devrede genede ihtiyaca göre işe yarar
Where do you buy the component it that
Good bro
BOOST XL6009 ?
👉❤👈
How many volt you give input
hi how can use another mosfet or transistor?
selam 800w golden motor ve 54v battery takili bisiklete ama yolda giderken battery kendince kapaniyor sence ne olabilir
5 am se 40am hoga kya ?
Buck canvator
Very good DC-DC step down converter
thx my frend
could you connect the load to see 60 amp?
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
Can this work on xl4005 Stepdown module? Cuz i don't have Lm2596
Can I use irfp064?
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! 😲
selamlar..zafer bey bu amper yükseltmeyi akım ayarı olan karttada uygulayabilirmiyim..HW-732..konvertörü kullanacagım şididen teşekkür ederim
Hocam 12v 5 w güç kaynağını 5 v 8 amper verecek şekilde nasıl ayarlayabiliriz. Step down regülatörü işime yarar mı amperi yükseltir mi?
Amper yükselmez
May we use this as charging regulator in vehicle
Muy interesante: Pero . utilizas un circuito conmutado para tener una tension estable a la salida. No pusiste el instrumento sobre la carga. basicamente es una resistencia variable en serie con la carga. deberias haber utilizado la tension de salida sobre la bobina par excitar los transistores y algun sistema de realimentacion para la tension. la eficencia del circuito en la conversion es muy mala a bajas tensiones debido a que no aprovechas los beneficios de la conmutacion de potencia.
.. en realidad el mosfet requiere tan infima corriente en el GATE, que no hay variacion de tension medible en DRAIN, contrario a lo que pasa con transistores bipolares. Un lazo de realimentacion, en una fuente conmutada de ese diseño, no se justifica, a no ser que se pretendan regulaciones de laboratorio, para lo cual existen fuentes de alimentacion dedicadas a tal proposito.
step up modülü böyle modifiye edip araba aküsü şarj edilebilir :)
how to up to 60A if YOU use step down LM2596S with maximun output 3A ????
Please make with step up booster xl6009 with transistor3055
In this case ,you changed from switching to linear
i have 3.7v 2A battery , will this circuit boost to 12v 4A ? plz reply 🙏
step up converter
modülü akım ayarlı bir model kullanarak aynı yerlerden çıkış vererek akım ayarlısını da kurabilirmiyiz teşekkürler
No lugar dos MOSFETS, daria para usar dois 2N3055, cada um com um resistor de 5w de 0,5 ohms?
Es geht doch eh sogar mit einem einfachen einzelnen LM Transistor. Das Step - Down - China Modell (Fehlbezeichnung für Spannungsteiler ) st eher nicht ganz im Kopf richtig ?
Why you do not show the the diagram of the circuit?
esto también sirve carga bateria de moto?
Regüla çıkış yük binice voltaj sabit kaliyormu.
It's good to be connected to a solar panel to charge acid/lead batteries
is it?
Bu devre güneş enerjisi şarj modülü olarak kullanılabilir mi?
отличная идея, если работает
output AC or DC?
very very nice work ..!
(does the output short circuit protection works ?)
thank you

Sir what is input voltage and amper
hi brother i want to regulate dc supply 16 volt and 250ampere please guide me
Thanks! Your video content is the safest and most useful
2:54 te Source olarak gösterilen bacak, devrede Drain olarak kullanılmış.
Bu devrenin girişini 50watlık bir solar panelle veya rüzgar türbinlerine bağlarsak çıkışından çok iyi bir verim voltajını alırız ve devrenin çıkış voltajı solar şarj cihazına bağlarsak jel aküleri bile şarj etmek mümkündür paylaştığın için teşekkürler
Aynen kardeşim
