I don't understand a single thing about electronics and neither does any of the explaining tell me anything, but I find these videos incredibly soothing and relaxing. Anybody else?

I've dreamed of such videos for YEARS...Namely, someone who would take an out-of-order piece of hardware and go through the board from the input to the output. I cannot thank you enough for your awesome content. I'm learning so much from you. Hats off to you

I would like to see more repairing video about power supply from you, you are such an expert in power supply I have learnt 80 % of my power supply knowledge from your channel and website and also tried to build my own power that was amazing... 👍👍👍👍 .. always amazing videos and thanks for sharing.. 🙂🙂

Very common fault on SMPS, you could show on oscilloscope the effect of a bad capacitors. Thanks!

Great video! I feel enriched when you take me through the thought process of troubleshooting.

Good fix on the heatsinks. I've filed down the tabs on those before. Still for the price that type of power supply is one of the best deals out there.

a minute ago i was thinking about you and badam!! you just posted this video!

perfectly described. I really love the narration. both the subject and the accent. a true "engineer"

Can you check some "Super fast chargers" ? For example the Huawei's "5V/2A or 9V/2A or 4V/10A" 40W SuoerCharger or something similar?

i always wondered about the X class capacitors and the Y class capacitors and when you would use them. i know you use a Y class between the hot and cold side of a power supply. so im glad i know now.. THANK YOU DANYK!!

No one explains PSUs like you. Excellent!

You are the best professor with power supply. I love that type of video

Soon as you removed the cover, I saw that it was the capacitors.

Excellent video! I have also just same esr meter as you have. It's really handy. My humble thanks.

April 1st idea: repair some devices sent by viewers, then put them back together as good as you can, and then initially present them as actually working and you having no idea why were they sent as broken or something. You could then actually show the repairing and all :D

You, my friend, are the best!

Great fix. That one's a keeper.

Could you maybe make a video series about making homemade SMPS and explain every aspect of the design, component choice, transformer construction etc.? I think it would be super interesting and very informative. Your tesla coil videos encouraged me to actually finally build one, because before I wasn't sure if I knew and understood everything. You explained every part very thoroughly and I learnt many things for sure! So, what do you think?

Thank you for your KZfaq Channel, I have learned a lot from you.

thank you for these videos they are very entertaining

Very informative video, thank you for posting it.

Nice repair video

good notice on transistors mounting brackets.

Excellent episode. THANX

Nice video, very well explained, as usual. 🙂 But smoothing capacitors do not see high frequencies. For these its more accurate to measure on their working frequency of 100 Hz.

Love Your videos!!!

I like videos diodegonewild, Keep up the good work :-)

The main capacitors after the rectifier are serialised. I read 220uF 250V. It gives 110uF. E=1/2.C.V2 Usually there is only one having U=400V

I wish I was so lucky that my repairs would have such an easy solutions. Last time I repaired similar power supply there was a problem with switching IC and burned resistor.

Super cool, Im a Fan of you👍👍👍👍👍

Thanks! I learned something new today. ⚡️👍🏻👍🏼👍🏽👍🏾👍🏿⚡️

Thanks for good video

good job nice work succes my friend

Would it better to overflow, or have a perfect amount of Thermal Paste in order for it to work the best ?

I have a 12A one and it emits high frequency sound too, it depends on the load too.

Very nice!

Thanks for the great videos! Do you have to remove the capacitors from the PCB in order to use the ESR tester? Did you do that for accuracy?

Thank you for your suppoRRRRRRt

Unique human!

It would been fun to actually know how much capacitance was left in these caps as well, as capacitance usually drops when they go bad like this. the capacitance was likely just a few percent on top of the higher ESR and the combination made the thing fail. I saw the caps 2 seconds after the cover was released and expected to see them even before you took the cover off considering how the supply was operating

Sir can you make a video on how you design snuber networks for you Hv circuits I would really appreciate that and I am also confused about the resistor values when designing circuits like a pre amp for feeding modulated sound in sstc circuits... Any help is really apprecited Regards

Bloody Hell, good job.

Merci 👍

Nice video and the obvious Capacitor failure, nice advice on the modification of the metal holders for the transistors :-)

can you discuss about x and y safety capacitors. how does it provide what is says it does?

I was planning to build a tesla coil with a High frequency driver like you have a while ago

Nice

I like your effort to reverse the circuit board because it s not easy. Anyway, you did not represent the feedback coming from the transistor of the optocoupler. It should return some Peak currents accordingly to the output power demand from the secondary. I can hear a very high frequency when you test the psu after fixing and having the load. I suggest you to try the app phyphox. There is a cool audio FFT spectrum analyzer. You could show us that the frequency is depending to the output power demand.

Hmm not much controlling the supply, reminds me of the cheap 12v and 5v bricks used for powering hard drives. One mosfet and 2 transistors and an opto coupler. When that supply was switched on and the tone came from it, i though Crap-a-ctors lol. I did not expect the primary 400v caps to be worn out, and they were not.

Can you please take apart the new apple 20w charger? Lots talk about it online.

Did you notice the spark coming from your power strip when you tested the power supply with the light bulb for the first time (2:20)?

I have collected lot of Capacitor from old circuit board : Nippon-Chemicon, Nischicon, Rubycon . Would i throw them ? Please Suggest me .

0:50 ... electrocuution - dat soundez interestiiiing :D Just like everything he says.

Awesome

HEY DIODEGONEWILD! I found a 12V 50A power supply on Ebay for less than 40$, which is incredibly cheap for the power! But isn't 600W a little bit too high for a halfbridge power supply, or at least without active PFC? I would really love a testing video of this power supply!

Please do a video series for LCD LED tv's repair

I was curious if we can convert a flyback smps supply from 0-12 volt.. The minimum i got was 3.3 volt but i need 0-12 volt... Is it possible i can give external supply to main switching control ic ... Will tl431 and other circuit work with it ??? Share your views.... It would highly appreciated... Thanks.

good

2:39 is it good to power both filaments at the same time?

I have a question, hope you will reply. Where did you buy that esr meter? Do you have link?

plz make a video on current flowing LED Indicator, i want to use in my battery charger, when i connect the battery LED Glow up to show its charging, and after disconnect the battery from charging LED Must be turn off, plz help (LED Should be glow stable and should not fluctuate )

awesome

Please, do more power supplies, hardware, motherboards, and expansion cards repairs/fixing. Also, I would like to ask, how long can stay capacitors charged, and be dangerous for health, in : Power supplies for computers. In CRT monitors. Is it in days, weeks or months?

Could you maybe also explain in the next episode why sometimes ultrafast recifier diodes are used? As far as I remember, in ATX PSUs the 3.3 and 5V rails are mostly rectified using Schottky diodes, whereas the 12V rail almost always is recified using ultrafast rectifier diodes.

Grate

I have A New Power supply with a sound only when there's Very low power. But as soon as I get more power for example my LED Light Strip it no longer has Noise. One other problem is when using extreme power changes for example my LED's flashing very fast and at. Different rates of speed the Noise comes. Back maybe even louder. Last issue is that I find that after 12 hours the Noise will stop when used at low power. Then I turn on the LED's and turn back off. So it uses more power then goes back to a small amount of power the Noise is back as if I just plugged it in.

You saying the word "ridiculus" sounds like some spell from Harry Potter :D

to me You are just like Tesla. You are amazing. A++++++++++++++++++++

Hi, i have a pascal 540w atx and when i load it voltage drops to 9-10v! I don't know what's the problem and how to fix it.

Nice, Please make video on Diesel engine Generator AVR reverse engineering schematic please.

What is the problem if Output LED of SMPS is flashing on and off 1 second?

@16:00 Why don't they connect a Schottky diode to the ground, instead of across the coil in a snubber RC filters to dissipate the recoils as heat? That way, the spike pulses (recoils) can go back to the main supply caps through the ground plane, and the spike's energy recovered. Minus the Ohmic losses of course, which would be about 3% tops. That would make the power supply 97% efficient! Theoretically of course. It will be electrically noisy and will throw RF of course. But could that not be handled with the right metal enclosure to act as an RF shield? If I can do it to a pulse DC motor, why can't I do it to a transformer? Please consider this questions for your next video.

What is the risk of running such power supply without a load (if that loading resistor was not present)?

How would I go about building a 2kw 100v dc power supply? Does rectifying one of those cheap SCRs work? Or is the power at lower voltages limited? I live in a 230v area. Maybe you guys can help me out. Thanks in advance!

My ears are well trained, before he opened the housing I could hear capacitors "screaming".

Can u sir explain about your watt meter its look like normal multimeter its a special multimeter u have made or if not than please give me a link of that meter so i can buy

👍

Love your accent , from what region or country that is?

niiiice

👍👍👍👍👍

What do you think about this design since there is not a SMPS chip? Actually, i was expecting a chip on the other side of the circuit board. Do you have

no need to draw the the schematic, you can download one from here: sxem [dot] org/2-vse-stati/19-istochniki-pitaniya/114-impulsnyj-blok-pitaniya-12v-5a-3a-1a it's S-60-12, your S-50-5 is the same but the transformer, LED resistor, 431 resistors and R10+C7 part

When the video will come?

make more vids about switch mode power supplys

what drives mosfet if there is no driver ic ??

@DiodeGoneWild - Oh this is dso clear , "pregnant" capacitors on secondary are 100% faulty , my cheap 400W PC- power supply (Intertech COBA [heating brick]) failed the same way after 5 Years of only low load (because I planned for a much more power hungray grafics card that I never bought)

Na těchto průmyslových zdrojích je dobré, že mají trimmer, takže lze pohodlně vykompenzovat úbytek napětí na vedení, jinak upřednostňuji zdroje na PCB, co číňani kuchaj z vyřazených spotřebičů a střílí to na ali za pár dolarů.

The caps fail more so in SM supplies because of the high frequency. Linear supplies live forever.

But why this supply has to switch between 110V 220V even though it's just 50 Watts, flyback power supplies are good up to about 120W 130W , over that power, you need to manually switch the Voltages. Maybe it's just the design probably.

Jinak ten zdroj je out, některé elektrolyty jsou viditelně "rozkvetlé".

Hahahahhahahaa i misses this voice way back 5yrs ago..

Hi sir good day.. My ender 3 3d printer psu stops working. There is only around 6volts in the output and the light is half lit.. Can you help me fix it.. Thank you

I love to hearing that heeeeeere heeeeere❤️❤️

15:41 were does the sound come from when plugged in?

S60SC6M masfett

Zdravím, rád bych něco přispěl na teardown. Je nějaká adresa kam můžu něco poslat? Díky zdraví Jara.

Was anybody else _concerned_ by the bogus compliance sticker on the motherboard? *ROUS* instead of *RoHS* caused me a long sigh...

heeeeeere and heeeeeere hahhaha .. cool

strange noises indeed...

Your cat doesn't accept it because he hasn't been seen :)
