In this video published by GreatScott! YouTube channel we will be having a look at the kind of power supplies you use every day – switched mode power supplies that convert our 230V AC mains voltage into for example 5V or 12V DC to power our electronics.
The topic will not only cover all about the heart of such a system, a flyback transformer, but it will also show you how it is used in a flyback circuit. At the end the video will also show you a DIY attempt of such a mains power supply that you should (please) not replicate.
