How A Switching Power Supply Works

Never mess with a man who draws and writes with both hands 💪

34:13 Capacitor passes AC to ground and blocks DC keeping it at the side of input power line, not letting it to ground. This produces even DC voltage at power line. This is the best education channel on YouTube :)

Thank you, Master Sorin. I Certify/Repair Air Traffic Control Systems for FAA in the USA and learn much from you. I have great respect! People like you make the world a better place!

Best electronics teacher, lesson for everyone, specialy for smart kids, beginners in electronics. We all need your lesson in electronics. Cel mai bun profesor de electronica, Sorin tine tot asa, cu totii avem nevoie de tine, de lectiile tale unice.

Sorin with each view of this video I understand more. Thank you.

[Dr.muthanna]

Thank you Sorin you are not only a practical person you’re an academic teacher

[steveolsen]

Great explanations. I've been in electronics since the mid 1960"s and have grown up with tubes, transistors, IC's, etc., etc., etc. BUT always the basics stay the same. Devices get smaller, power demands increase, but the theory (and physics) stays the same. It's not magic (usually). Keep it up! We are never to old to learn. We just need better eyes ;-). (You didn't explain that the "B" power term comes from using a "B" battery used in the 20's with the A, B and C battery radios.)

Sorin you will have to correct it because not to confuse transistor opening with with a lock as it does here but it's understandable when you say open you mean is able to lead (Transition status) position of the switch (N.O) means normally open
  -you're doing a good job
Gentlemen, take this opportunity to learn

I was waiting for a video like this /for a teacher like Him/ for 20 years! Maybe more! Thank You, Sir!

Absolutely brilliant demonstration with the analogue meter and the capacitor to show how a capacitor works to iron out the ripple of an ac signal, smoothing it out to create a nice dc supply for the output stage of a power

[patrickmaritano]

Thank you so much Sorin for the time you spent for our knowledge !

[allangumikiriza]

Keep it up for not being selfish with all this great knowledge in electronics

[samchrome-gv]

Thank you for the expiation, very clear now, and all those capacitors are connected in parallel. because they are connected to the power positive. They work hard.

[maxgrove]

Excellent video Sorin. Makes it all clear now thanks.

[janparra]

Sorin you are the best and Thank you for simplifying for us a hard subject

[saysles]

I love your explanations. I was taught to use open when switch doesn't pass and closed when it does pass.

Now i understand why this channel was called " Electronic repair school " ❤

[JulioSantos-upgz]

Very nice explanation Sr.!
God bless you!

[janosgajda]

Thank you for the video. One thing got into my mind: Sorin is the first bio-mechanical component in a switching power supply :)

[allangumikiriza]

You are the greatest technician i ever seen
some times i do wonder how you mastered all this electronics
