HELLO,
this is prashant,btech ece(2nd year). I hv 2 submit a project& the project name is clap switch. i have a problem for makin report & how i would make on pcb 2 get neat &clean diagram. i hv ckt diagram also& i hv done on bread board. in the ckt 3 transistor,2 led &capacitor, resistor used.when i go for pcb it look sm complicate. so can u plz help me 2 get simple diagram on pcb.

thnks ....etc

Hai,

I need full details regarding the SMPS.
Like SMPS working,its ckt diagram & the formulas used for designing the ckt, types of SMPS & its application etc.

Thank you ....etc

Abstract

This paper presents the design of a clap activated switch device that will serve well in different phono-controlled applications, providing inexpensive key and at the same time flee from false triggering. This involves the design of various sages consisting of the pickup transducer, low frequency, audio low power and low noise amplifier, timer, bistable and switches. It also consists of special network components to prevent false triggering and ensure desired performance objectives. A decade counter IC serves the bistabl ....etc

CLAP SWITCH


General Description
This is a circuit that can be used to turn a device on
and off by sound only, hand clapping, whistling etc.
Can be used to turn the lights on and off, in security
systems. When triggered the circuit will stay in the
on or off condition till it is triggered again.

Technical Specifications -

Characteristics
Working voltage : 230V AC
Current : 60mA
Contact Rating : 3A/ 6A as per the kit selected.
Warning
VISHA kits are s ....etc

CLAP SWITCH THEORY
Here is a circuit for electronics hobbyists that can switch on & off a light, Fan, Radio etc. by the sound of clap.The sound of clap is received by a small microphone that is shown biased by resistor R1 in the circuit. The microphone changes sound wave in to electrical wave which is further amplified by Q1. Transistor Q1 is used as common emitter circuit to amplify weak signals received by the microphone. Amplified output from the collector of transistor Q1 is then feed to the Bistable M ....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

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


Abstract obtained from IEEE 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
