Computer Smps Diagram. The output dc dc stage in any smps always contains one or more switching devices that periodically commutate lc networks. This page contains a simple smps circuit which is capable of producing 12 volt dc with 1 amps current rating and this circuit contains few easily available components it may help you to design your own smps for your electronics projects.
The voltage available from a wall outlet is a poorly regulated ac ranged worldwide from 90v to 240v while most electronic circuits require a well stabilized. This tutorial is designed to help you better understand the operation of an smps. Smps offers advantages in terms of size weight cost efficiency and overall performance.
Smps circuit is operated by switching and hence the voltages vary continuously.
3 0 1 shows a block diagram example of a typical smps with an ac mains line input and a regulated dc output. In modern computer psu this voltage is typically 375 400 vdc. The output dc dc stage in any smps always contains one or more switching devices that periodically commutate lc networks. Smps offers advantages in terms of size weight cost efficiency and overall performance.
