Device of switching power supply unit and principle of operation. The video shows the PSU without a cover, types of power supplies, how linear (transformer) and inverter (pulse) power supply with schematics, the structure of input and output filters, the purpose of chokes, capacitors, diodes, transformers, transistors and controllers. Also this animation shows what a modern pulse transformer consists of, how the current is rectified, what is used to eliminate electromagnetic interference, why you need grounding in a UPS and the purpose of power transistors, and diodes.
