We are remaking a pulse power supply for a different voltage using a laptop power supply as an example. In the video, I forgot to say that winding two turns is not a dogma, sometimes more is needed, the main thing is that the unit starts up confidently without a load and remember that under load, the voltage on the winding we have changed will increase so that it can exceed the supply voltage of the PWM controller and the voltage of the capacitor in its supply. Therefore, we wind up the minimum number of turns for a confident start and no more. Sorry for the jerky picture, I am recording on my phone and the Internet access point was turned on on it and it was throttling and the video is not so smooth, next time I will be more careful!
