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 ....etc

BACKGROUND STUDY
PV System and Principle of operation
A photovoltaic cell converts energy from the sunlight into electricity. The radiation from the sun is made up of tiny particles of energy called photons. As these photons impact on the cell, some of them are absorbed into the cell. The energy from the photons on impact causes electrons to be free . The movement of the free electrons is what generates electricity.
A PV system is made up of a combination of many cells. Since a PV module is made up of cells comb ....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 red ....etc

INTRODUCTION

Boost converter is one of the most popular choices for high-quality rectification. The converter is supplied from a full-wave rectified line voltage and operated so that the input current follows the input voltage. The input current shaping can be achieved using a number of techniques. When the converter is operated at fixed frequency and fixed duty ratio in the discontinuous conduction mode (DCM), the low- frequency component of the input current is approxi ....etc

Thyristor RAM ('T-RAM) is a new type of DRAM computer memory invented and developed by T-RAM Semiconductor, which departs from the usual designs of memory cells, combining the strengths of the DRAM and SRAM: high speed and high volume. This technology exploits the electrical property known as negative differential resistance and is called thin capacitively-coupled thyristor used to create memory cells capable of very high packing densities. This memory is highly scalable and already has a storage density that is several times higher than found ....etc
