(iii) Compare the merits and demerits of SMPS vis-a-vis linear power supplies. (iv) Interpret Power supply specifications. 21.1 Introduction to regulated dc power supplies. Power supply is a broad term but this lesson is restricted to discussion of circuits that generate a fixed or controllable magnitude dc voltage from the
27 Sep 2007 This article was also featured in Maxim's Engineering Journal, vol. 61 (PDF, 440kB). Considering the multiple DC voltage levels required by many electronic devices, designers need a way to Unlike linear regulators, which can only step down an input, SMPS are attractive because a topology can be.
9 Oct 2007 The industry drive toward smaller, lighter and more efficient electronics has led to the development of the. Switch Mode Power Supply (SMPS). There are several topologies commonly used to implement SMPS. This application note, which is the first of a two-part series, explains the basics of different SMPS.
To show how one can arrive at a practical circuit from consideration of basic circuit theory. ?. To show how circuit theory can be used to explain phenomena observed in practical circuits. ?. To show how a switch mode power supply can be systematically cons-tructed, starting from the simplest converter topology.

HOW AN SMPS WORKS. Block diagram of a mains operated AC-DC SMPS with output voltage regulation. Rectifier stage. AC, half-wave and full wave rectified signals. If the SMPS has an AC input, then its first job is to convert the input to DC. This is called rectification.
Switch-Mode Power Supply Basics. The prevailing DC power supply architecture in most modern systems is the Switch-Mode Power Supply (SMPS), which is known for its ability to handle changing loads efficiently. The power signal path of a typical SMPS includes passive, active, and magnetic components. The SMPS
