Smps Schematic Diagram. This switching power supply was built because i needed a powerfull adjustable bench power supply. For clarity the parts responsible for miscellaneous auxiliary functions such as current limit fan control and ov protection which are not essential for learning the.
12v input supply may be acquired from an atx power supply. This is a conceptual circuit diagram of the power train of a typical atx computer power supply unit. The diagram below shows a partial schematic of a 450 watt atx power supply.

In such a segment tny268pn could provide 15w output. We will add the components list soon. So the input high voltage ac supply 230v is given to the rectifier and it converted into high voltage dc 230v. Finally everything is done in three easy steps and the schematic is generated.
