Introduction to Power Electronics

EBook Description: Power Electronics is the technology associated with efficient conversion, control and conditioning of electric power from its available input into the desired electrical output form. The field of the book is concerned of electrical power processing using electronic devices the key component of which is a switching power converter.

As marching into the digital era, many people in different sectors are quite keen to understand why this has happened. They hope to obtain basic principles about digital signals and associated digital systems. Instead of targeting advanced or expert level, they often hope to grasp the subject as efficient and effective as possible without undertaking impossible task under usually limited time and effort available. This book is written for those beginners who want to gain an overview of the topic, understand the basic methods and know how to deal with basic digital signals and systems.

Biological Signal Analysis

This textbook will provide the reader with an understanding of biological signals and digital signal analysis techniques such as conditioning, filtering, feature extraction, classification and statistical validation for solving practical biological signal analysis problems using MATLAB.

Digital Image Processing: Part II

This book (vol.1 and vol.2) introduces the fundamental theories of modern digital image processing including intensity transformations, filtering in the frequency and spatial domain, restoration, colour processing, morphological operations, and segmentation. It aims to help the students, scientists, and practitioners to understand the concepts through illustrations and examples

Electromagnetism

This is a companion volume to Electromagnetism for Electronic Engineers (3rd edn.) (Ventus, 2009). It contains the worked examples, together with worked solutions to the end of chapter examples, which featured in the previous edition of the book. I have discovered and corrected a number of mistakes in the previous edition.

I hope that students will find these 88 worked examples helpful in illustrating how the fundamental laws of electromagnetism can be applied to a range of problems. I have maintained the emphasis on examples which may be of practical value and on the assumptions and approximations which are needed. In many cases the purpose of the calculations is to find the circuit properties of a component so that the link between the complementary circuit and field descriptions of a problem are illustrated.

Introductory Finite Difference Methods for PDEs

This book presents finite difference methods for solving partial differential equations (PDEs) and also general concepts like stability, boundary conditions etc. Material is in order of increasing complexity (from elliptic PDEs to hyperbolic systems) with related theory included in appendices. Each chapter has written and computer exercises with web links to worked solutions, programs, A/V presentations and case studies. Emphasis is on the practical and students are encouraged to do numerical experiments. This book is intended for undergraduates who know Calculus and introductory programming.

An Introduction to Nonlinearity in Control Systems

The book is concerned with the effects of nonlinearity in feedback control systems and techniques which can be used to design feedback loops containing nonlinear elements. After a short introductory chapter on nonlinearity and its possible effects the use of phase plane methods for nonlinear second order systems is discussed. The next three chapters cover the describing function method and its applications in the determination of limit cycles, stability analysis and the prediction of unique nonlinear behaviour such as jump resonance and subharmonic generation. The following chapter shows using the Tsypkin approach how in feedback loops with a relay nonlinearity any limit cycles and their stability can be found exactly. Examples are given which cover some unique forms of limit cycles such as limit cycles with a sliding mode and multipulse limit cycles, which can be caused by resonant plant transfer functions. In recent years with the advent of microprocessor controllers there has been considerable interest in techniques for controller tuning based on limit cycle data and this is the topic covered in the next chapter. The analyses used make use of both the describing function method and the Tsypkin method presented in the previous chapters. The next topic covered is absolute stability methods for a nonlinear feedback loop with a single nonlinearity with emphasis placed on frequency domain methods to allow comparison with describing function results. The final chapter covers some methods for the design of nonlinear systems. The material is of an introductory nature but hopefully gives an overview and provides a basic understanding of various topics, many developed in recent years, and several of which have entire textbooks devoted to them.

Intro to Computer Based Control Systems

This book introduces the concepts of hardware, software, and communication aspects of computer aided measurement and control systems and discusses techno-commercial benefits of such systems for its application in process industries.

Electric Drive Systems and Operation

This book is intended primarily for the secondary-level and university-level learners of an electromechanical profile, including the bachelor and master students majored in electrical engineering and mechatronics. It will help also technicians and engineers of respective specialities.

If you have completed the basics of electricity, electronics, mechanics, and computer science, the book will guide you in appreciation of applications built on the basis of electrical motors. In addition, you will know many electromechanical products and determine their important differences.
