How to Make a Voltage and Current Adjustable Short Circuit Protected Adjustable Power Supply 30V/10A

[@rastanpiruz]

Kaç yıldır kanalınıza üyeyim.Farsça konuşuyorum ve Türkçe açıklamalarınızdan hiçbir şey anlamıyorum ancak 30 yıldır teorik ve pratik elektronikle çalıştığım için video çalışmalarınızı anlıyorum.Teşekkürler Biz İranlıların söylediği gibi tekrar teşekkür ederiz.

Hola Zafer , querria saber si podrias hacer algo parecido y simple como esta fuente usando el LM317hvt que puede entregar desde 1,2 vdc - 55 vdc y un comparador operacional simple lm 311 y un mosfet irf540n.

[@СмыслМеждуСтрок]

*_You can install multi-turn resistors for more precise adjustment of voltage and current._*

[@ZAFERYILDIZ52]

Absolutely right

[@jorgereccia9675]

Zafer : Felicitaciones !!!muchas gracias por este aporte, para muchos principiantes que necesitan una fuente todo terreno , facil de construir y con proteccion y limitacion y explicado con las imagenes ; querria saber si funciona igual o mejor con un mosfet a la salida .solo lamento que el youtube no tiene una IA para que pueda traducir automaticamente al español ,por si se pudiera hacer en forma hablada como lo hacia Ampletos (construya su video rockola)

[@betopx2]

The integrated circuit working with 32 volts in its power supply can burn out and work at its limit. You could place a resistor and a 12v Zener diode on pin 8 of the integrated circuit to prevent it from burning.

[@ZAFERYILDIZ52]

Yes it is possible to improve the circuit

[@vitalyne...]

The maximum power of such power supplies depends on the transistor. And almost any transistor in linear mode can withstand no more than 35-40W (on any radiator and even with strong cooling). This means the maximum power of such units is 35W, taking into account losses))) Example: input 32V - output 3V, the difference 29V is the heat loss on the transistor! Even the most powerful transistor can handle 40W in linear mode... 40W: 29V = 1.3A.. TOTAL! If you load more, the transistor will burn out almost immediately... Another example: at 12V output we have - 32-12=20V (into heat for the transistor!), which means 40:20=2A... and regardless of the input voltage and current... The only way out is to do 2..3..5..10.., and at least 100 transistors in parallel)))))

[@alitopcu9220]

If a mosfet, which can carry high current, is added instead of a transistor, a higher current can be drawn from the output, meaning the circuit can be improved. This depends on your experience.

[@vitalyne...]

In linear circuits, everything depends on the power dissipation of the transistor. A transistor, which, according to the datasheet, can pass currents up to 100A and has a power of 200W (for example), STILL in linear mode - WILL BURN if the power passed through it exceeds approximately 40W... Because in the datasheet, the parameters for the PULSE mode are indicated, and such circuits are LINEAR. And here you either need to add a lot of transistors, or switch the windings at the input (so that the input/output voltage drop difference is minimal).

[@rahulkoley6161]

@@vitalyne... Can u tell me... One thing.... I have an a atx computer power supply... I already increased its voltage to 14.5v.... If I install two 3205 mosfet parallal with the above constant current circuit... Can I able to charge a 12v car battery to 14v with 5amp constant current... Here the input output difference is only 2v....??

[@vitalyne...]

@@rahulkoley6161 According to the datasheet, the power of the 3205 is stated to be 200W. however this is for pulse operation. In linear mode, almost any transistor (medium and high power) can withstand an average of 40-45 W, and this is with a good radiator and cooling. Those. Practically, in order not to bother yourself with calculations, you can simply divide the declared power of the transistor by 4, or better yet, by 5. So for transistor 3205 we have 200:5=40W Based on this number, we make further calculations. We have 14.5V at the input, for example 12.5V at the output, the difference is 14.5-12.5=2V Therefore P=U*I, hence the current I=P/U, I= 40/2=20A Theoretically, one transistor on a good radiator and cooler will be enough for you. Keep in mind that the 40W that we “calculated” is the maximum thermal power that the transistor can withstand! In reality, it is better to play it safe and count a little less... let's say about 30-35W. Then the transistor is guaranteed to have an easier time. 2 transistors in total will handle a power of about 65-70W. Theoretically, the power dissipated in your case is 2 * 5A = 10 W and one transistor will cope, but 2 pieces are much better))) Although 10W seems like a small amount of power, the transistors will still heat up quite noticeably (alas, this is a linear mode...), so even they need a good heatsink (and better still, a cooler)

Zafer: Tebrikler!!! Bu katkınızdan dolayı çok teşekkür ederim, yeni başlayanlar için yapımı kolay, korumalı ve sınırlamalı, görsellerle anlatılmış bir çeşmeye ihtiyaç duyuyor; Çıkışta bir mosfet ile aynı mı yoksa daha iyi mi çalıştığını bilmek istiyorum. Ampletos'un yaptığı gibi sözlü olarak yapılabilmesi durumunda KZbin'un otomatik olarak İspanyolcaya çevrilebilmesi için bir yapay zekaya sahip olmamasından dolayı üzgünüm.

[@chinmoy1955]

The caption says 30V 10 ampere but this circuit cannot supply 10 amps. His demo shows a max of about 1.8 amp. If this circuit is capable of 10 amp, then please demonstrate that.

[@bobmchenry7993]

Brilliant circuit, I want to power a Raspberry Pi 4 so will fix it to 5.1volts, what is the max current output of this circuit. Thank you

[@SilvanaGaspari]

If there is 10 A at the output, the 0.15 Ohm 5 W resistor used to read the output current would dissipate 15 W and this resistor has a theoretical maximum dissipable power of 5 W. If there are 10 A at the output, the D1047 transistor should, in many output voltage conditions, dissipate more power than its theoretical maximum dissipable power which is 100 W.

[@kennedy67951]

I like your channel and your work. I think you should expand your Circuits to off grid to Earth Batteries so if no Power all this could be done without dependence on pay as you grids. Just my opinion mate.

[@ZAFERYILDIZ52]

Thanks for the comment and support yes it is true

[@kevincaravario6266]

Hi, I have a doubt! When you short-circuit it, the current regulation comes into operation and the voltage drops to 0? or what is the behavior? Thank you very much in advance for your response!!

The voltage does not drop to zero, but it draws close to 3 volts

I don't have a 10A LOAD, but you can get 10 amp outputs by cooling the transistor.
