This is perhaps the most detailed explanation pfc part of smps on youtube. This series is greatly helpful because the power supply being explained is from a ps4, an immensely famous device. I will have to revisit this series often because it has become a point of reference in my learning endevour. A big thank you to Haseeb who is continually pouring out precious gems in technical education.

I always enjoy watching your teachings. You are able to enlarge my layman understanding of SMPS electronics every time.

Love this series. Trying to apply the knowledge you have given to the adp-300cr power supply. Thank you

I love this PS4 videos, thank you

Thanks for the demonstration 💝💝💝

جزاك الله خيرا اخي ، شرح ممتاز

Well explained tutorial 👌

so much knowledge.. amazing.. thank you, master.. so glad I found your videos.. now I will be able to fix my customers SMPS hopefully on time.. :)

Nice video 👍👍👍👍

Super, it is like music. Thanks

amazing analysis.

Thanks for sharing good knowledge my brother thanks

This my second time I am watching your amazing vid, we really need to know the process of electronics cards and what is the purpose of every component on the board what is it's functionality, after that we can fix stuff, many many thanks for your big offers I really broad of your channel

fully watched awesome superb informative sharing big thumbs 70 thanks best regards for your adorable work

Wonderful video dear friend, have a happy weekend!!!

Lk 5 Assalamualaikum bhai Very well explained 👍😇

👍 *_# 87 and hearty greetings to you and your channel, dear Haseeb Electronics! Thank you for this interesting upload, I am glad that I have watched it. Best wishes to you from your LW who remains one of your channel's loyal fans._* 🙋🎄 🎅

I understood PFC Thank you sir 🙏🏻🙏🏻🙏🏻🙏🏻

Very nice

Brilliant! Your my favorite Haseeb! 😊

Saty Blessed & Wish You Good Luck My Dear Brother Big Thumbs Up # 36

Приветик спасибо за обзор интересно было посмотреть.

Thank you my Friend 👍🙏🏻

SOOO GOOD

Good morning 🙏 bhai Great upload 👌 👍

This vid was really rear so much info, I like to investigate more complex SMP and I want to ask about schematic how can I get SMP schematic since I have an Emerson SMP with 24vdc and 40A, asking for your help brother Haseeb. Many thanks and this channel is the best one

Good like this information

very good. thank you.

Our exceptional Haseeb 👍

Lk 89 wonderful ❤❤👍😊

Salam M Haseeb, nice to see you back ! can you put a load on the output to see how good it regulates. I have an Xbox 16A but the voltage drop is high (2v for 5A bulb lamp) Thank and Salam Aleikum.

Salam brother. Great tutorial, thank you A same psu came in the other day with that coil you mentioned in the PFC circuit fractured, The console seems turning on just fine but it gives that strong burning plastic smell. Is there a possibility to replace that coil with another from pc PSUs ?

Makmal hony tk dakh raha , nice work dear friend

Hi iam working on a sharp TU-T2HR32DVR has no stand by light 12v is present at the input and there is 3.3v at I.C. Of number EM78P311N pin 28 VDD microprocessor. I have dis connect the HDD but still the fault still there I Dried to get the schematic diagram no success any ideas please !!!

Hi Haseeb, really THANK YOU for your nice & clear explanations on The switching power supply! I would like to read your general opinion on the PFC circuitry can be found nowadays inside switching power supplies, expecially the bigger ones. In repairing, I find them, several times almost completely blown-out. I've found this circuitry usually right in before the mains bridge and usually works with it's own controller circuitry & power switching device. To quickly remove the SMPS fault, even while accepting some degradation of the appliance itself, would it be a good idea to functionally remove this circuitry? Several times I find a lot complex PFC circuitry, that are so damaged thati it wouyld be almost impossible eve identify the components have been used! For example, right now I'm repairing an Air conditioner SMPS, in which the PFC power IGBT completely blown out together it's controller, which marking is unfortunately completely unreadable . In other occasions, I removed this circuit, and it seems to work, (of course not take into account EU normatives). I would like to know, your opinion on this. Ciao from Italy! Mario Di Stefano

Hi, haseeb, my ps4 ADP-200ER power supply capacitor is blown, i want to replace the capacitor, can you plz tell me which capacitor to put. please help me with capacitor reading. thank you.

What components should I look up to if the 12v keeps dropping to almost 0 Volts after switching the Power Supply? Great Video !

What is the value of the big colorful resistor ?

Fault finding methods pfc primary side 320v main cap ok but no vcc to pfc ic running vcc auxiliary winding

good afternoon, could you tell me the value of resistors r53 and r54? thank you in advance thank you

Hello brother thanks for your video, New subscriber. I want to connect a GPS tracker ( DC 9V - 95V ) to this power supply can yo please tell me where to use? Thanks for your informative teachings

Hi. Great video, very informative. I have the same ps4 psu, but the pfc is not staring when i engage the 5 v with the standby. the big cap stays at 322 v and , obviously, i don’t have the 12 v output. There is no voltage at pin 6 or 7 (where it should be 15 v) of the ic. What component provides the 15v to the ic.? What should I check next?

Good, you have the same of adp-240ar

thanks for sharing knowledge on power supply, but how to increase current not voltage of output???

You said in the next video you will discuss high power section. But next video is final video that is standby section. My psu has standby 4.75v but on shorting 5v and acdc_stby, 12v is not getting on. 🥺

hello thank you for all his information, if I lose the 400v when I turn on the ps4 the problem can come from where please? (no 12v) the standby is ok

Hi Mr Haseeb. If current sense resistor is out, would it cause the whole psu to not work?

pfc smps when test with series lamp why we on off the lamp

And it is a reactor....

12 volte missing, only standby 5 volte, how can doing?

Sir ❤❤❤❤❤ hide ma chiya tha

You are repeating the same thing over and over and over and over and over and over, there are no information or real explanation , just repeating and observing the out come. do you thing you know how to explain ??????????????
