{1070} Why PFC is used in SMPS? Power Factor Correction

[@amritpatel3794]

When you talking about Science, Technology & Engineering , avoid Religious greeting. Did you hear any non-muslim guy start with religious greeting for Technical Videos?

[@HaseebElectronics]

thanks a lot for your vauable suggestion. it is not any kind of preach. it is just wishing peace and blessings for my every viewer. i don;t care about any religion. because every religion is valuable for me. and i respect for everyone. no problem, if someone gets annoyed by my wishes. he can skip the video. its translation is; "Peace be upon you as well as God's mercy and blessings"

[@HaseebElectronics]

if someone not takes start with any greetings. that is his routine, i have no concern but i pray and wish peace and blessings for my viewers. it is my routine

[@amritpatel3794]

@HaseebElectronics Just do the appropriate gestures at different occasions. Pray & religious greeting at a religious place. But don't bring it to knowledge sharing platforms. It looks non-sense.

[@amritpatel3794]

@HaseebElectronics This is the reason why followers of Islam are not at the forefront of science and technology. They inject self perceived religious superiority talk on every platform. I know 1 phase & 3 phase active PFC in depth, but I will not share with religious minded people.

[@HaseebElectronics]

no problem dear. if it is annoying for anyone, he can leave my channel. because the viewer can select his preffered channel.

[@jvjv6213]

Thanks for noticed my question. Now I can understand why PFC CIRCUIT used in high watt smps . Thank you So much Haseeb bhai . Hu to Mai India me rehne wala banda pr aap se bahot kuchh shikh raha hu .

Dear Habib Bhai 🙏. You have explained nicely in details on regulation factor for low power SMPS but you have cut short detailed explanation on PFC operation for high power SMPS. Of course it is not easy to understand PFC application in High Power SMPS or inverter supply or PFC application for IPM etc for commoners without their detailed study of advanced power supply application designs. But the overall explanation was very impressive. Thank you so much 👍

[@saarike]

Absolutely Great!!!! My humble thanks. Now i understand PFC completely.

[@g4z-kb7ct]

This is a very interesting topic. It would be good to visually see PSU with PFC circuit connected to multimeters and oscilloscope at multiple points (switching IC, PFC IC etc) to see actual changes in input voltage and switching duty cycle when load and input voltage is changed while the PSU is working. If you have adjustable load and adjustable power supply maybe you can do this in a future video.

[@HaseebElectronics]

thanks a lot sure i will arrange a detailed practical session with all possible checkpoints

[@g4z-kb7ct]

@@HaseebElectronicsexcellent. thank you.

[@sunny-yj5tb]

Excellent explanation sir..... learning many concepts from your videos...one doubt.....if pfc controler is there then ,will there be necessary for output feedback to pwm controller,for output regulation ,or pfc will manage by its own.....

[@HaseebElectronics]

PFC controller maintains voltage on DC rail. PWM needs feedback to compensate output variations caused by load

[@sunny-yj5tb]

@@HaseebElectronics thankyou very much for replying sir....

[@saukhilalnishad3370]

Excellent video sir

[@W1RMD]

Great explanation! I was wonder if the flashing in the series bulb in most of your video is due to the PFC circuit ramping up the voltage in steps to slowly and more efficiently charge the bulk capacitor? Can you see the bulb flashing with your eyes or is it an effect of the camera sync. Thanks again and have a great weekend.

[@HaseebElectronics]

thansk a lot for your valuable appreciation yes the series lamp flashes and it is observed visually it is due to linear increase in smooting capacitor until the volatge value on DC rail is not maintained, the PFC controller tries to use maximum duty cycle which results to dropping the line voltage due to series lamp, which causes to turn off PFC controller thus line volatge regain, and PFC controller restrts this reboot process remains active until the volatge are maintained on DC rail

[@danialhp6743]

Hi bro Thanks for your best tutorial I have a question, in this video you said, if we decrease duty cycle, output voltage will drop or if we increase duty cycle the voltage will increase, but in another video: You said that the flyback works with the reverse duty cycle, that is, if the transistor is active, we have no output, and if it is not, we have an output. But in this video you said the opposite

[@sumuduasiri]

Thanks very much sir. Well explained 🙏🙏🙏

[@German_byte]

Many thanks for that explanation.

[@HaseebElectronics]

You are welcome!

[@bartdepauw1156]

So, PFC controller is also switching at very high frequency as each 50 Hz period starts with very low voltage ? So it also ameliorates the power factor as current is now taken whole the 50 Hz period ?

[@mohamedantri9433]

It's very informative video think you sir ❤❤❤❤🎉🎉🎉🎉🎉

[@PinoScimia-rx3pi]

[@susantaatha6468]

Very nice information. But sir some PFC circuit inductor use AC line. How it works inductor.

[@HaseebElectronics]

yes there is bridge rectifier based PFC and the other is Bridgeless PFC circuit

[@necipsahin8377]

Dear brother you are explaining the pfc as not correctly. Pfc is power factor correction. I mean it is about current and voltage angle correction to maximum output power and reduce the power loss. As for me you have to research pfc function better. Power=voltage x current x CosQ and if you want to get full power and reduce the power loss you must correct cosQ=1, for this, you must measure the angle of current and use sense resistor and voltage angle then you determine the zero point of voltage, What did you use all for these? The current is forward on capacitor and the current is backward on bobin. If you don’t balance the angle of the output, cosQ will be reduce. Here Pfc is used for this.

Selamün aleyküm kardeşim bir sorum var. Bu videodaki 12:36 civarındaki yerde tl431 ve oktokuplöre gelen bağlantı yolu aynı hat üzerinden geliyor. Bu doğru mu yoksa yanlışlıkla mı çizildi. Doğru ise oktoküplör GND ile bağlantısını nasıl sağlıyor da led yanıyor😮 tl431 in altındaki dirençin bağlı olduğu GND den mi devreyi tamamlıyor😊

[@BJcanal270]

Wiating 😊

[@piccoloijo]

Is it posible to use TL431 for output under 2.5V?

[@HaseebElectronics]

No For that purpose a zener can be used to operate optocoupler

[@salehneyestani7627]

Hi sir, I have a pfc laptop adapter, when no load connect to it, I have about 500v on big capacitor (100uf 420v) that goes up dangerously, when I switch off it, capacitor voltage don't drop. With load on output, it works normally, 340v on capacitor, and when switch off, capacitor voltage drop fast to 0. Do you have any idea what's wrong about it?

[@JoshuaAdeoye-u8f]

How do you determine that the voltage across the inductor is 80v? Or is it just an assumption?

[@g4z-kb7ct]

So basically PFC exists only because of different main voltages in different countries when high amperage output is required? If all voltage was 240V, PFC would not be needed?

[@HaseebElectronics]

Exactly yes It compensates the line variations. It assists the PWM controller to maintain output side of the SMPS
