In this video number {1070}, Why PFC is used in SMPS? Power Factor Correction, I explained pfc in smps switch mode power upply circuit. it is volatge booster section, which boosts the rectified dc voltage. it supports the pwm controller to regulate output voltage. if the line volatge drops, this volatge booster maintains on dc rail.

Assalamo alycom wa ruLLAHy wa brakatuh dear brother, I need help urgently. I have invt solar transformer, it's GD100-011G-4-PV . I accidentally reversed the incoming poles from the solar plates, where by what look like two resistors on top of each other blew up. My problem is that I can't tell their ratings. I searched the internet but with no avail. Can you be of help ? Thanks in advance

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.

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 4 ай бұрын

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

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

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 ?

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😊

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?

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

@@HaseebElectronics I am impressed by your heart to comment of your good self. Nevertheless, this response from you, full of many bla bla, speaks volumes of your shallow knowledge on the subject. No explanation is to the point. Please search for the part name that has been used in the circuit and study well. These are non-polar capacitors. When used in series in AC supply, these produce reactive resistance. This is dependent on its value in mfd and hz of AC. I don't expect that you may digest any more knowledge on it. Happy ignorant expert.
