Non linear analog circuits and its equalization techniques



INTRODUCTION

The confluence of Moore s law and the maturation of the art of analog integrated circuit (IC) design has created a flurry of recent research and development work on digitally intelligent analog circuits. Exploiting high-density on-chip digital processing, the approach represents a trendy alternative to conventional hard-labored analog design methodology, in which the inescapable trade-off between linea ....etc

Pulse Based Dead Time Compensator for PWM Voltage Inverters



I. Introduction
The state of the art in motor control provides an adjustable
voltage and frequency to the terminals of the motor
through a pulse width modulated (PWM) voltage source inverter
drive. As the power devices change switching states,
a dead time exists. Although the dead time is short, it
causes deviations from the desired fundamental output voltage.
While each deviation does not appreciably affect the
fundamental voltage, the ac ....etc

ADAPTIVE AND NON-LINEAR EXCITATION CONTROL OF SYNCHRONOUS GENERATOR S STABILITY THROUGH NEURAL NETWORK

ABSTRACT
Adaptive and non linear Excitation control of synchronous generator s stability through Neural Network Control equipment of synchronous generators such as automatic voltage regulators, speed governors and power system stabilizers have been developed to maintain stability and to improve damping of the power systems. When an operating condition changes greatly, however, such controllers may become less effective bec ....etc

A New Simplified Space Vector PWM Method for Three-Level Inverters


I. INTRODUCTION
RECENTLY, with the dramatic improvements in high
voltage technologies, high voltage insulated gate bipolar
transistor (HVIGBT) and gate commutated thyristor (GCT) are
expanding the area of their application. For the high performance
ac drive systems at increased power level, high quality
inverter output with low harmonic loss and torque pulsation
is necessary. In case of the conventional two-level inverter
con ....etc

Abstract
A general pulsewidth modulation (PWM) method for control of four-switch three-phase inverters is presented. The proposed vector PWM offers a simple method to select three or four vectors that effectively synthesize the desired output voltage, even in presence of voltage oscillations across the two dc-link capacitors. The method utilizes the so called space vector modulation, and includes its scalar version. Different vector combinations are compared. The effect ofWye and delta motor winding connections over the pulse width modu ....etc

Abstract:
The number of industry applications in which induction motors are fed by static frequency inverters is growing fast and, although much has already been done within this field, there is still a lot to be studied/understood regarding such applications. The advance of variable speed drives systems engineering increasingly leads to the need of specific technical guidance provision by electrical machines and drives manufacturers, In this paper we have studied and developed a simulink model with PWM inverter and find out the variou ....etc
