This is simple isolated power supply video. This video shows step by step how to design isolated power supply. The simple isolated power supply adalah flyback topology. This topology is chosen because it s safety, has a little noise and the unit production. This video focus on the flyback topology. In flyback topology, the transformer s used in two purpose,they are for energy store and oscillation. Here is the video:
This video also explain the flyback topology with the optocoupler and secondary side regulator. Without optocoupler, the flyback topology still can be made using LT3573. Using LT3573, the schematic is simpler than the flyback topology with optocoupler and secondary side regulator. This video also shows the typical waveform of the flyback topology.
