Abstract”
This paper presents a simplified sinusoidal uninterruptible power supply (UPS) system. The proposed scheme includes features such as high power factor, low total harmonic distortion and good dynamic response at the ac output voltage. In addition, the scheme has the desirable characteristics of high efficiency, simple circuit and low cost compared with a traditional standalone multiple stages UPS with power factor correction. The paper also presents the circuit operation, the analysis and, experimental results of the proposed U ....etc

Seminar Report On SWITCH MODE POWER SUPPLY
ABSTRACT
The report is an overview of Switch Mode Power Supply abbreviated as SMPS. The purpose of report is to provide a general understanding of SMPS and its applications. There is a brief discussion of historical development of SMPS, followed by the common topologies of the same. The principle of operation is described which is almost same for all the topologies. Then the steady state analysis is discussed to have an insight of the operation under ideal and real conditions. The ....etc

A Digital DC Power Supply (programmable bench power supply unit), hardware version 3.0
Abstract:
A good, reliable and easy to use bench power supply unit is probably the most important and most used device in every electronic lab.
A proper electronically stabilized bench power supply unit is an important but also expensive device. Using a microcontroller based design we can build a power supply which has a lot of extra features, is easy to build and very affordable.
