Digital Electronics II (EET 202/3)

A series of papers on business, economics, and financial sciences, management selected from International Conference on Business, Economics, and Financial Sciences, Management are included in this volume. Management in all business and organizational activities is the act of getting people together to accomplish desired goals and objectives using available resources efficiently and effectively. Management comprises planning, organizing, staffing, leading or directing, and controlling an organization (a group of one or more people or entities) or effort for the purpose of accomplishing a goal. Resourcing encompasses the deployment and manipulation of human resources, financial resources, technological resources and natural resources. The proceedings of BEFM2011 focuses on the various aspects of advances in Business, Economics, and Financial Sciences, Management and provides a chance for academic and industry professionals to discuss recent progress in the area of Business, Economics, and Financial Sciences, Management. It is hoped that the present book will be useful to experts and professors, both specialists and graduate students in the related fields.

The purpose of this book is to describe the theory of Digital Power Electronics and its applications. The authors apply digital control theory to power electronics in a manner thoroughly different from the traditional, analog control scheme. In order to apply digital control theory to power electronics, the authors define a number of new parameters, including the energy factor, pumping energy, stored energy, time constant, and damping time constant. These parameters differ from traditional parameters such as the power factor, power transfer efficiency, ripple factor, and total harmonic distortion. These new parameters result in the definition of new mathematical modeling: A zero-order-hold (ZOH) is used to simulate all AC/DC rectifiers. A first-order-hold (FOH) is used to simulate all DC/AC inverters. A second-order-hold (SOH) is used to simulate all DC/DC converters. A first-order-hold (FOH) is used to simulate all AC/AC (AC/DC/AC) converters.

The second edition of this book incorporates the comments and suggestions of my friends and students who have critically studied the first edition. In this edition the changes and additions have been made and subject matter has been rearranged at some places. The purpose of this text is to provide a comprehensive and up-to-date study of the principles of operation of solid state devices, their basic circuits and application of these circuits to various electronic systems, so that it can serve as a standard text not only for universities and colleges but also for technical institutes. This book also aims to those who are working in industries and military and wish to bridge the gap between the old technology and present day IC-technology.
