integrated gate commutated thyristor igct ppt

The integrated gate-commutated thyristor (IGCT) is a power semiconductor electronic device, used for switching electric current in industrial equipment. It is related to the gate turn-off (GTO) thyristor. It was jointly developed by Mitsubishi and ABB.Like the GTO thyristor, the IGCT is a fully controllable power switch, meaning that it can be turned both on and off by its control terminal (the gate). Gate drive electronics are integrated with the thyristor device.

ABSTRACT
The Integrated Gate Commutated Thyristor (IGCT) combines the advantages of the hard driven GTO thyristor, including its dramatically improved turn- off performance, with technological breakthroughs at the device, gate-drive and application levels. Homogenous switching area of the IGCT up to the dynamic avalanche limits. Snubber circuits are no longer needed. Improved loss characteristics allow high frequency applications extending into the kHz range. A new IGCT device ....etc

Data Compression

Abstract :

It is very interesting that data can be compressed because it insinuates that information that we generally pass on to each other can be said in shorter information units (infos). Instead of saying yes a simple nod can do the same work, but by transmitting lesser data. In his 1948 paper, A Mathematical Theory of Communication, Shannon established that there is a fundamental limit to lossless data compression. This limit, called the entropy rate, is denoted by H. The exact value of H depends on the informatio ....etc

Abstract
As Internet access becomes a basic necessity, alternative ways to go on-line without a computer will be required by mobile professionals, the visually impaired, and people without access to computers. Voice/speech based interface options will become an important part of the overall solution to access the Internet content. As the need for an alternative access method to the Internet has become evident, progress continues to be made by technologists to provide such solutions.
One key area of focus has been voice-based technology, ....etc

An IGCT is a special type of thyristor similar to a GTO. They can be turned on and off by a gate signal, have lower conduction loss as compared to GTOs, and withstand higher rates of voltage rise (dv/dt), such that no snubber is required for most applications.

The structure of an IGCT is very similar to a GTO thyristor. In an IGCT, the gate turn off current is greater than the anode current. This results in a complete elimination of minority carrier injection from the lower PN junction and faster turn off times. The main difference is a redu ....etc

Ping of death:Denial of Service Attacks-An Emerging Vulnerability for the Connected Network
abstract
denying access to essential
services by legitimate users is the main aim of the increasing new types of attacks in internet. This maybe through methods like crashing servers or routers, overwhelming the network with huge traffic to degrade the traffic. a readily available software program is all that one needs to launch a denial of service attack(DoS).

Thyristor technology is inherently superior to transistor for blocking voltage values above 2.5kV, plasma distributions equal to those of diodes offering the best trade-off between the on-state and blocking voltages. Until the introduction of newer power switches, the only serious contenders for high-power transportation systems and other applications were the GTO (thyristor), with its cumbersome snubbers, and the IGBT (transistor), with its inherently high losses. Until now, adding the gate turn-off feature has re ....etc

Abstract
The electronic commerce with digital content over the open, unsecured network like the Internet provides opportunities as well as risks for content providers. So far, most content providers of media and entertainment content such as music, film, or print content have not been successful or profitable in charging consumers for their products. Nor have they been successful in creating the technology frameworks required to remunerate on the one-hand content owners and on the other hand protect against piracy. T ....etc

Artificial Intelligence is all about bringing Common Sense, Expert Knowledge, and Superhuman Reasoning to Computers. For the most part, AI does not produce stand-alone systems, but instead adds knowledge and reasoning to existing applications, databases, and environments, to make them friendlier, smarter, and more sensitive to user behavior and changes in their environments. In the domain of Artificial intelligence, various problem-solving techniques have been developed. Though working towards the common goal of making a computer 'intelligent', ....etc
