@paulcohen1555 3 года назад

As already mentioned before, the output electrolytic filter capacitor and rectifier MUST BE CHANGED for such higher voltage MOD. Also other problems may arise depending on the circuit topology and implementation. Personally I would not MOD a 5V P.S. for more than 9V.

@test-rj2vl 2 года назад

Yes, I was expecting it to pop when it went above 12V. This video also lacks explanation. Do you happen to know why zener diode and why this stabilizer was was soldered the way it was (I mean pinout relative to potentiometer + resistor).

@portabelcomp 3 года назад

Alhamdulillah.. tadi saya kira ini menggunakan transistor tapi setelah lihat datasheet ini bukan transistor tapi sejenis rangkaian gabungan transistor dioda yang kakinya di namai anoda, katoda dan referensi.. Selain itu saran dari yang coment bahwa elco output di tukar dengan yang lebih besar voltasenya, ya.. itu lebih bagus.. Keren bro

@giorgostexnikos6976 3 года назад

its dangerous to use as you go over the limit.change the output electrolytic capasitor to 25v before use.

@zoltankecse991 3 года назад

I agree.

@zoltankecse991 3 года назад

..otherwise the small value cap gonna be explode

@sarockpashotan3938 3 года назад

You can change with a 25 voles capacitor as i did!!!

@gabrielcuevas5837 3 года назад

@vhannezajhoycaparoso6385 3 года назад

If change it to 25v electrolytic capacitor, how much is the uf?

@djsavage2421 3 года назад

Let me start out by saying ты жжешь. I cheated I use a translator but I want to thank you for translating this into English it’s most helpful when you can understand something in your native tongue and duplicate it with instructions. Again thank you again for this great idea it will prove to be very useful on quite a few projects that I have that need to be controlling the voltage output.

Greetings from across the pond from a fellow Romanian tinkerer such as yourself! Nice job!

@AIexanderHartdegen 2 года назад

I need to say that is a nice idea (I made it to adjust some rare transformer to different operatus). But you need to know that the good way to process is that it's dangerous to reach twice or more the initial value. Voltage regulating here comes from a PWM wich change duty signal to provide highter voltage. First HV circuit is not made to work in that range of tight pulse. This is the reason why you must use this tip to have voltage as less as you want, but for reliability and safeness, don't reach more than twice the value... This primary circuit is not design to regulate until this point.

@KUBA64official 3 года назад

I am not sure if the output electrolythic capacitor of 5V power source is rated for 15V. I would change it.

@zuhair_alawad 3 года назад

Yeah, this is the first thing I thought about after it exceeded the six volts. That's make it a fire hazard. But overall, the idea is as good as always.

Great idea but make sure those caps are rated for at least 15 volts. And it would be better if you explained the theory of operation as well.

@davidca96 3 года назад

true, most cheap ones you find like this have 10v rated output caps if its a 5v supply, so thats definitely something to also switch out or it wont last long.

@anwarigroup 3 года назад

The output capacitor value should not be less than the output voltage, otherwise, it will explode. You need to carefully check other components effect when you change the voltage. It may be useful in some cases, but it needs knowledge and understanding of components, current, voltage and ohm law.

Very nice and informative video. I think english is not your first language and I thank you for making an english version. But having one language superimposed upon another language makes it very difficult to understand. I think it would be better to use your native language with english subtitles instead. I hope you view this as constructive criticism. The video is great and I really liked it. Thumbs up.

The circuit using TL431 is very inefficient. Original adapter can only be used up to 2A, 6.5A can't be taken out. The circuit will burn in few minutes.

@szaki95 3 года назад

It's not because of the TL431, it only gives a reference. In any system if you raise the voltage the max current will be lower, but if you know the maths then you know that 5V 2A gives the same power as 10V 1A.

@peschex0d 3 года назад

Even if this charger uses a Shottky diode, the thermal power at 6A x 0,4V would be high enough to melt the solder off the PCB ((( or burn the diode down, because there is no heatsink. Also I doubt the transformer wiring would accept such a high current.

@Michel-7.7.7 3 года назад

I would solder the metal case of the Poti to the 240v live wire, so it can't touch it by accident. In this case at least you can be sure touching it is dangerous

@semiliterati 2 года назад

I don't know man. I looked inside my trashcan. No knobs. No stickers. I couldn't find anything I could describe as "cool", or "cool looking". It was mostly just various kinds of food packing materials, just like the stuff I buy at the grocery store comes in. There was some spoiled leftovers too, but it didn't seem like the value they bring my power supply project warranted digging them out. Full disclosure, I don't have the trashcan's manual, and can't verify if I'm actually having a technical problem, or if it's just user error, but I feel like I'm using it right. My guess is it's just broken

S. What do You Think ?.

@klonikFPV 3 года назад

Great solution to resurrect old power supplies but Please ba aware that usual in Chinese Power supplies output capacitors are only bit higher than nominal voltage. If you will have constantly 15V having "stock" 6,3V capacitor your power supply will not live long time.

Use atleast 50v 600 to 1000 uf capacitor, as tl431 works within 36 v , then there is less chance to BOOM. Remember to use tl431 or zener diode otherwise there will definitely Boom in abscence of zener or tl431
