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

Here is a simple power resumption alarm circuit that can be fixed inside the switch box itself. It gives beeps when the power resumes after a power failure. This circuit is ideal to monitor battery chargers, since the long duration power failure may sometimes remain unnoticed. The circuit is too simple and derives power supply using a capacitor.

Capacitor CX, Resistors R1,R2 and Fullwave Rectifier comprising D1through D4 forms the power supply section to drop 230 volt AC to low volt AC. Capacitor C1 filters the ripples from AC so that around ....etc

ABSTRACT

The Rapid growth of technology has made our life easier. This advancement in technology also increased the traffic hazards. Hence the ratio of road accidents which take place frequently increases causing immense loss of life due to poor emergency facilities. Main causes behind these road accidents include: lack of training institutes, unskilled drivers, poor road conditions, use of cell phone during driving, over loading and poor governmental plans in this regard. Our research provides a solution for accident detection and prevention ....etc

Am rema,want to know about an efficient common mode hybrid filter used in SMPS for my seminar work.

Abstract obtained from IEE is After the study of electromagnetic interference (EMI)
mechanisms in switching mode power system (SMPS) and the soft
switch, this paper proposes a novel hybrid filter (HEF) to suppress
commend mode EMI in SMPS. The HEF consists of a passive filter
and an active filter. Matching network, which can reduce
impedance mismatching effects, is introduced in passive part. A
feed-forward active filter is adopted ....etc

Abstract
A major disadvantage of applying sliding mode control to dc/dc converters is that the steady-state switching frequency is affected by line and load variations. This is undesirable as it complicates the design of the input and output filters. To reduce switching frequency deviation in the events of line and load variations, an adaptive feedforward control scheme that varies the hysteresis band according to the change of line input voltage and an adaptive feedback control scheme that varies the control parameter (i.e., sliding coeffic ....etc
