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 inescapab ....etc

Simple Non-Linear Magnetic Analysis for Permanent-MagnetMotors



The need


In the process of designing a new motor/generator;
Method of Finite Element Analysis is used

The disadvantage - Computing time

Alternate option – Nonlinear Magnetic Analysis on an equivalent magnetic circuit of the whole machine

Because of Magnetic Saturation in Stator teeth, the analysis becomes Nonlinear.



The procedure



The permeance values of t ....etc

Adaptive Non-linear Congestion Controller for Differentiated-Services Framework (Java)
IEEE/ACM Transactions on Networking, Vol. 13, No. 1, February 2005

Abstract:
The growing demand of computer usage requires efficient ways of managing network traffic in order to avoid or at least limit the level of congestion in cases where increases in bandwidth are not desirable or possible. In this paper we developed and analyzed a generic Integrated Dynamic Congestion Control (IDCC) scheme for controlling traffic using information on the stat ....etc

Power Factor Correction of Linear and Non-linear Loads Employing a Single Phase Active Power Filter Based on a Full-Bridge Current Source Inverter Controlled Through the Sensor of the AC Mains Current
Abstract:
In the last years the number of non-linear loads has been increasing rapidly. This non-linear load had drawn a current form the AC Mains with harmonic components, leading to low power factor, low efficiency, interference by the EMI, among others. A classic solution is the use of passive filters, which ....etc

Introduction

Ex: An ultrasonic signal at 200kHz and another one at 201kHz will generate a 1kHz tone and a 401kHz signal which is inaudible to the human ear.

If an AM signal with a non-zero carrier amplitude is passed through Air, it is self-demodulated

ABSTRACT

The holddown Spring is one of the major components of a fuel assembly for PWR. It holds the fuel assembly firmly seated down on the lower core plate and allows the FA axial movement caused from the irradiation growth of guide thimbles. Depending on the up-lift force of a fuel assembly, from 2 to 4 leaves are assembled to be a set of a spring pack and it is fixed on the frame of the top end piece by screw. The spring can deflect so greatly during operat ....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 b ....etc

In this paper, the implementation of a shunt active power filter with a small series reactor for a three-phase system is presented. The system consists of multiple non-linear loads, which are a combination of harmonic current sources and harmonic voltage sources, with significant unbalanced components.The filter consists of a three-phase current-controlled voltage source inverter (CC-VSI) with a filter inductance at the ac output and a dc-bus capacitor. The CC-VSI is operated to directly control the ac grid current to be sinuso ....etc
