Again a masterclass to learn and enjoy the electronics.congratulations and thank you!

Excellent as always. Thanks for sharing your knowledge and experience with us.

Un grand merci pour le partage de ces précieuses informations,et un grand merci aussi pour pour la peine déployée pour répondre aux commentaires . Tutoriel très très utile et instructif, souhaitons qu'il y aura d'autres sembles et merci encore.

Outstanding! I am an amateur radio operator and back in April, we had a power outage due to a snow storm. The power went on and off several times before going out permanently. After the power came back on, A terrible noise was on all different bands and frequencies up to 20 Mhz. Recently the noise stopped. I assume the switch mode power supply at my neighbors "died". Thank goodness! The closest neighbor's house is over 200 meters from here and I checked with an am radio to determine the source of the noise. I think it was even going back into the power lines because I could still here the noise all the way down the street! I think an arching MOV would create a LOT of noise, and it's before any rfi filter in the circuit. Take care!

Excellent detail! Thanks for a great clear and concise explanation.

Exelente explicacion sobre fuentes conmutadas, felicitaciones mi amigo. Saludos desde Peru.

Thanks for the explanation. There was another capacitor that you replaced. Where is that one is in the circuit?

may u please use your oscilloscopein primary troubleshooting to see tha actual use im afraid once i buy and use the osci in the primary

Good

👍

Thanks for sharing Haaseb can you help me with this I want to read voltage with an isolated ground Mine setup is 4x 12v battery with 4x solar controllers with 1x Esp32 and 2x ADS1115

Hello sir, have you seen a board where the feedback pin is connected to gnd in 3842b? If you see it, I would appreciate it if you could explain about this design. Sincerely

Hi, I watch your videos anout smps ,I assume you have already explain power factor correction PFC ,but can't find on yours video , need explanation why is used how is it works ,how to test etc... tnx

I'm working on TCL TV. There is stable 24v and 3.3v. at the standby light led board there is 3.3v stable but led doesnt glow. Occasionally it can light but then go out when I try to power up? With stable voltages , I can't imagine what part is the problem? Any ideas to check?

6:53 i have a question, if this power supply provide a 400W for example, what will happen if i connect 400W lamps in total? Another question please, if i want to restore this psu into service after this fault is it better to replace all electrolytic caps? Thank you very much 😊

220V/100W Lamp is connected on 220V input, not on 24V output. If you connect 400W lamp on input, the chances are the supply won't work at all due to voltage drop on its input. Even if it starts, the small load on output will shut it down due to input under-voltage. Recap is always a good idea if the PSU is old or used in harsh conditions. If the PSU is relatively new no need to change all caps.

@@miroslavstevic2036 i mean, if its rated for 400W and there is short circuit, using 400W lamp will prevent the Mov from smoking? This what i meant. Thx for the reply

@@Solder_it 400W lamp will lower the short-circuit current through the damaged MOV. Only way to tell will it smoke is to actually try, otherwise it's unpredictable (depends on the MOV damage).

Can you find unknown components in chinese smps

Who is the P.S. manufacturer? Which controller IC is used? Maybe I will find a circuit diagram that is close enough to have a better view.

Could you please elaborate a bit on those 2 diodes for the auxiliary power? kzread.info/dash/bejne/iY2gu7pwYK2saNY.html I don't understand that schematic Great informative video, as always. Thank you for training us, your audience 🙂

Maybe report these devices as having a chronic issue? Also, you could break a different part of the board and make it seem like a new fault to fix!! lol ;)
