Excellent Content .. Thank You for sharing .. Cheers :)

Is it part of future made SMPS

Great

How does Partial pfc outdoor unit of air conditioner circuit work? (IGBTs for Partial Switching PFC )

Wow

Is it correct to say the switching of the inductor by the transistor forces current to keep flowing in phase and negates the capacitor behaviour of making current shift from phase. Is that the main principle why the correction takes place?

when turning on a device, a peek current flows thru the aperatus and the grid
like switching a light bulb a lot. can make it break it sooner then useal.

maybe.. a dc towards dc, converters is just a transformator. that two coil thing around a metal block. that works with a magnetic field.

for example makeing from 12 volt , 6 volts. kind of thing.

Why are my diaphragm air pump pulling 2x as much as the rated power? I have 4 pump running at the same time, 2x 85w+ 1x 55w + 1x 22w. So the total is supposed to be 247w or 1.12amps. But why my ammeter is constantly reading at 2.2amps? Is my power factot 0.5? How can correct this?

Nice Video, Can you make video about active harmonic filter? and total harmonic distortion

I'm going to have to watch this again a few more times. It was explained extremely well, but I still got lost about 3 minutes near the end of the video. I'm thinking I might slow down the speed 0.75 and absorb what I missed. Thank you sincerely sir. You are a very very good teacher, that's why in the end I'm confident I will understand 😊

professor
the input current of inductor will not like sine
as the inductor add harmonics to the signal.
the circuit between DC to DC and rectifier bridge is boost dc dc converter

Hello there, hope you are doing well; I have a question: As you explained when the power factor correction is made- by PFC block, the input waveform of current becomes sine-like again. But I am curious to know what happens to the output waveform of current. What does it look like?

Thank you for the wonderful educational videos

Thank you for this interesting explanation.
Just I find that the mosfet is kind of short circuiting the bridge rectified output.
Isn't it?

Your explanation is ohhhhho too good brother appreciate your hard work
Please make video on components like MOSFET transi,etc

My experience with inductors is that they're more efficient, in continuous conduction mode. It seems that the Eddy losses in the inductor core are much higher in critical conduction mode, because the lower effective switching speed allows deeper penetration of magnetic flux into the core. At higher frequencies, the skin effect reduces the conductive cross section, reducing overall core loss, despite a possible increase in hysteresis loss.

why do we multiply the error signal (which is the output of the comparator, comparing the output voltage and REF signal ) with the input voltage? The output of that multiplier is compared again with a current signal to feed the switch driver. My point is, Is it possible to compare a voltage signal with a current signal ?

Hi bro nice explaining. I have a question. I am online gamer and we found out after so many years because of weird input lags and other things that the real problem is the reactive current. And nobody know how we can reduce this reactive current in our pc´s and monitors with the internet router box. We really need help because this Reactivecurrentcompensators are toooo expensive and not good for a private house or apartment. its too big. pls help us anyone.
