Smps Power Supply Circuit Diagram. In a switch mode power supply circuit diagram the input ac is first rectified and filtered to produce relevant magnitude of dc. Its construction is typical for a modern computer psu with mosfet switches and active power factor correction pfc.
The diagram below shows a partial schematic of a 450 watt atx power supply. This site is smps power electronics information guide. Secondly ee20 core flyback transformer as stepdown transformer which is made up of compact ferrite ee.
The switching frequency is around 100 khz.
How smps adapters work. How smps adapters work. The field of engineering that deals with the design and analysis of power conversion circuits and devices is called power electronics although power supply design is a true cross disciplinary task. The efficiency of linear power supply is 40 to 50.
