DESIGN AND IMPLEMENTATION OF DIGITAL DIMMING ELECTRONIC BALLAST -Advisor: He Jinman Graduate Student: Wang Ming Shan-CHUN YUAN CHRISTIAN UNIVERSITY



DESIGN AND IMPLEMENTATION OF DIGITAL DIMMING ELECTRONIC BALLAST
Advisor: He Jinman Graduate Student: Wang Ming Shan China 2002 CHUN YUAN CHRISTIAN UNIVERSITY .

Abstract
 This thesis aims to present the design and practice of a digital electronic ballast for fluorescent lamps. It introduces the characteristics of lamp, DC/DC converter, power factor correction circuit IC 6561, and resonant circuit IC 6574, The electronic ballast is developed by using IC 6561and IC 6574, and other circuits to meet the need for high power factor, long lamp life, high luminous efficiency, and dimming control. Also the circuit operation principle, analysis of carefully designed circuit parameters, practical consideration of self-excitation, and dimming control are explained in detail .The test of real design is carried out at last, and the result shows the proposed digital electronic ballast can fulfill the design purposes.

This paper present s the 3- phase hybrid series active filter in order to compensate for harmonics currents , voltage fluctuating and voltage unbalance in power systems . The electric power systems are based on an alternating current and voltage which are sinusoidal in nature. Computers and sensitive electronic control equipment in industrial and commercial plants demand a high quality electric power supply . With significant development of power electronics technology , the proliferation of nonlinear loads such as static power converters has deteriorated power quality in power systems . Notably , nonlinear loads resulted in harmonic distortion , become a serious problem in many industrial equipment . Therefore, utility power quality has become an important issue recently .

A Novel Design of an Adaptive PID Controller for Cardiac Pacemaker Achu Govind K. Aravind Sekhar Vinod B.- Dept. of Electronics and Communication, Mohandas College of Engineering, Kerala University, Trivandrum- Kerala, India



Abstract
 Biomedical engineering deals with the application of various concepts of engineering in the field of medicine and biology mainly for health care purposes thereby improving patients quality of life. Out of the various techniques, the primary focus is to develop a reliable and optimized technique for electro simulation of heart. The present work deals with an improvement in the design of control system for regulating the heart rate of a pacemaker in an efficient way. An Adaptive PID controller based on the Delta rule and Adaptive Correction Factor is proposed in this paper. The Adaptive PID controller is implemented using an Adaptive Loop incorporating MIT rule with the Delta rule. The PID parameters are modified by an Adaptive Correction Factor. Simulation results were performed on the developed cardiovascular system of humans and results show that the proposed adaptive PID controller produces superior control performance than conventional PID controller. Simulations were done in Matlab/Simulink.
 Keywords: Adaptive PID Controller, Adaptive Correction Factor, MIT Rule, Delta Rule, Pacemaker, Heart Rate.
