DESCRIPTION OF THE PROJECT
The circuit given here is of a very useful and accurate digital voltmeter with LED display using the ICL7107 from Intersil. The ICL7107 is a high performance, low power, 3.5 digit analog to digital converter. The IC includes internal circuitry for seven segment decoders, display drivers, reference voltage source and a clock. The power dissipation is less th ....etc

mini projet report
Voltage source inverters (VSI) have been widely used in uninterruptible power supplies, unified power flow controllers or unified power quality conditioners, and distributed generation systems (DGS). VSIs are inherently efficient, compact, and economical devices used to control power flow and provide quality supply. VSIs can be classified as voltage-controlled VSIs (VCVSIs) and current-controlled VSIs (CCVSIs), depending on their control mechanism. In this paper, a detailed comparison of VCVSIs and CCVSIs for DG ....etc

SEMINAR ON MICROPROCESSOR BASED LENGTH MEASUREMENT

INTRODUCTION
An electronic scale and length measurement apparatus including electronic length measurement transducer for providing an electrical signal indicative of the length of an object to be measured.

These signals are processed by an electronic signal processing circuit including a microprocessor, a ROM and a transducer.

CONVENTIONAL LENGTH MEASURING DEVICE
The conventional length measuring devices are that they have no memory.

A High Input Voltage Three-Phase ZVZCS DC-DC Converter with Vin /3 Voltage Stress on Primary Switches
Abstract
A high-voltage three-phase ZVZCS dc-dc converterwith low voltage stress is presented in this paper. The voltagestress on the primary switches is only one-third of the inputvoltage. By using the phase shift pulsewidth modulation (PWM)and secondary snubber, four of the six primary switches areoperating with zero-voltage switching (ZVS) and two of them areoperating with zero-current switching (ZCS), in order to reducethe switch ....etc

Measurement and simulation of the electric field of high voltage
suspension insulators

Vassiliki T. Kontargyri, Ioannis F. Gonos*,y and Ioannis A. Stathopulos



INTRODUCTION
The insulator strings, which are used for the suspension of overhead transmission lines, constitute one of the most important parts of
the transmission lines as they used to give support to electrical conductors and shield them from ground or other conductors as well
as they provide the necessary mechanical suppo ....etc
