  That was the best explanation of a high frequency smps supply I’ve ever seen. Tyvm. Your a great teacher.

  Honestly, I have asked at least 50 engineers and professors, &nbsp;&quot;How does a modern charger/adapter work? Why is it so much lighter than the old ones? &nbsp;How does it cool down after fully charging the battery? &quot; Surprisingly, not a single one could answer. As if they have never learned how SMPS works. Then I had to tell them how it works. You are the first one who explained it correctly and simply, plus added a few things more than I knew. Thank you.<br>I hope you get a million subscribers. Then next time, please show the inside of a a broken (old) charger/adapter to make it even more exciting. If I could give you 5 star rating, I would have given you 7 stars.

  Finally, someone explained in detail the purpose of this connection &nbsp;and how to make pulses with transformer and transistor.

  Finally I understood why there&apos;s a diode+capacitor present accross the auxiliary coil.<br><br>The auxiliary coil does 3 things:<br><br>1) It charges the diode+capacitor tank, which can be readily emptied by the photo-transistor to turn on the T2.<br><br>2) It pushes current through capacitor into the base of T1 to turn it on completely.<br><br>3) As the T1 capacitor gets fully charged, its base current gets reduced, which again makes the T1 partially turned on. This negative change in magnetic flux induces reverse current in the auxiliary coil. That reverse current spike is pushed into the base of T2, turning it on and ultimately turning off the T1.<br>As soon as the reverse current spike disappears, the T2 gets turned off and we are again in the same position as we were in the beginning.<br><br>Thank you for this video! 🙏
