A prototype of a fully electronic on-load semiconductor tap changer for power transformer has been
designed and built. With the emergence of high power semiconductor devices, problems associated with the mechanical on-load tap changer have been properly rectified. In this work, the prototype was constructed with triacs as the switching devices and microcontroller as the triggering circuit. The results obtained from this work show that the prototype has a faster time response of approximately 0.44s to react to any load chang ....etc

Abstract:

In this paper, analysis of CDMA network with Optical Amplifiers has been done. As the optical amplifier provides gain as well as has nonlinear characterstics, gain is expected due to signal amplification as well as operation of SOAs as limiter due to gain saturation. In this paper results have been computed for with different SOA placements in a typical star topology employing CDMA. The results show that in a star topology network employing CDMA, placement of SOAs before CDMA decoder does provide benefit due to g ....etc

A transistor is a semiconductor device used to amplify



A transistor is a semiconductor device used to amplify and switch electronic signals. It is made of a solid piece of semiconductor material, with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be much more than th ....etc

Over the years semiconductor devices have set a new trend in the field of electronics and created waves in the existing technology of memory storage. Flash memory which has been in use for long now, is now being replaced by new advents in technology of memory such as Ferro Electric Memory, Magneto resistive Type Memory and Ovonic Unified Memory. This paper contrasts the working of flash kind of memory used in Dynamic “ RAMS with that of the other types mentioned above. In brief, advantages over the flash kind of memory are evaluated a ....etc

Organic material that has semiconductor properties. Semiconductivity is exhibited by single molecules, short chain (oligomers) and organic polymers. Semiconducting small molecules (aromatic hydrocarbons) include the polycyclic aromatic compounds pentacene, anthracene,and The environment of surface electrons at 'solid-to-liquid' interfaces is somewhat extreme, subjected to intense local electric fields or harsh chemical pressures that high-density ionic charge or polarization of mobile molecules create. In this proceedings, we argue functions of ....etc
