{1228} VCC, Current Sense & Feedback Relationship in SMPS Controller

In this video number {1228} VCC, Current Sense & Feedback Relationship in SMPS Controller. I explained what is vcc voltage, vdd voltage, current sense signal in smps pwm controller ic, what is feedback signal in UC3842 / UC3843 / UC3844 / UC3845 and UCC28742 current mode pwm controller switching ICs. i explained relationship between UVLO thresholds and working volatge, standby current and working currents.

Thanks for explaining and for all this information ❤

[@W1RMD]

Wonderful video! Thanks and have a great day.

[@carlosgomes6074]

Thank you sir, for this very informative video. I have a pioneer music centre hi-fi that is having this problem. This explanation of how the protection circuit is working will help me to locate the fault . Thank you, sir.

[@jorgeramalho8386]

Excellent presentation. Thank you and congratulations.

[@EmmanuelKalinde]

Detailed explanation. Thank you Sir

[@HaseebElectronics]

You are very welcome.

[@ruudb72]

Thanks for the nice explaination!

[@HaseebElectronics]

You're welcome!

[@francescvilches3967]

Excellent video. Willing to see the practice where we play with current sense pin.

[@rajkhumar001]

Really clear explanation sir. If your time permit, make video about MOSFET &igbt gate resistance calculation and its different type. It will be more helpful. Thank you.

[@W1RMD]

Yes, I was going to ask the same question. Why a 27 ohm at the gate, sometimes a 10 ohm, sometimes 100 ohms. Some have a pull down resistor some do not. What about push pull or H bridge? If you don't shut off the gates at the right moment, you ruin the mosfet or device. Great question!

[@rajkhumar001]

@W1RMD basically gate resistance are low value resistance. Depending upon its internal capacitance. So you get a different type of resistance.

Thank you sir hasseeb

[@karltest1314]

Thank you. Very informative

[@HaseebElectronics]

it is my pleasure

[@MarkPrince1317]

Thank you very much brother that was very informative if possible next video about pwm IC with microcontroller Thank you

[@turkialshehri9762]

amazing explinations🎉

Great video, as always. It would be nice to make video on TL494 which is classic voltage mode controller, used in so many S.M.P.Ss. Especially it's error amplifiers, soft start (dead time pin) e.t.c. I even have used it for dc motor speed control, for the motor had tachogenerator who's output voltage is proportional to the shaft speed. Motor was from satellite antena dish servo positioning drive.

[@bones1225]

Great vid.

[@8500gtNvidia]

Hello master Haseeb. Thx for you informative video. Can you explain what happens if we have a short on the schottky diode on the coil's output? Yesterday i shorted by mistake the Double schottky diode and the PWM IC exploded, the Mosfet shorted out with it a bounch of resistors and 1 diode on the PWM side. What happend there? Why the coil generated a short on the PWM and Mosfet, if the output diode shorted? Did i get the 320v on the PWM? Pls explain me, thank you again for your work!

[@MbaduMalonda-sc5dg]

hi Sir much appredciated, can you please explain on a half bridge smps how pusle transformer drives the 2 transistors , what voltage is applied on the base of bjt to switch the transistor off while the other transistor is On because i assume the pulse produces ac voltage instead of dc voltage

[@cankan9566]

Hi sir , CA 888 module does not work in some flyback transformers. What is the reason for this?Can you explain this in a video

[@ahmedabdelkader8223]

Pls can you show me how to test module SKKt 15/16 thyristor bridge

[@samircmps7260]

And aleykum selam, can you help me with something? I want the exterior door light to detect my approach and turn on when I approach the house 100 meters, how can we do this, thank you. Can anyone help with this?

[@abidsaleem5070]

Please we need this video in Urdu

[@HaseebElectronics]

sure. i am recording it today
