In this video we are building a 12V flyback power supply. I have drawn its block diagram, and we solder it block by block. I tell you about the selection of components for the power supply, and I show you how to wind a transformer for it. In the second part we will finish our power supply, describe its operation and draw a clearer diagram, and test it.
