Electrical drives in general play a key role in power generation, household appliances, automotive and industrial applications. The rapidly expanding area of adjustable speed drives as used in robotics, wind turbines and hybrid vehicles is driven by innovations in machine design, power semi-conductors, digital signal processors and simulation software.

Fundamentals of Electrical Drives is for readers with a basic engineering knowledge who have a need or desire to comprehend and apply the theory and simulation methods which are applied by drive specialist throughout the world.

This book provides a unique approach to derive model-based torque controllers for all types of Lorentz force machines, i.e. DC, synchronous and induction machines. The rotating transformer model forms the basis for the generalized modeling approach of rotating field machines, which leads to the development of universal field-oriented control algorithms. Contrary to this, direct torque control algorithms, using observer-based methods, are developed for switched reluctance machines.

Tutorials are included at the end of each chapter, and the reader is encouraged to execute these tutorials in order to gain familiarity with the dynamic behavior of drive systems. This updated edition uses PLECS® simulation and vector processing tools that were specifically adopted for the purpose of these hands-on tutorials. Hence, Advanced Electrical Drives encourages “learning by doing” and the experienced drive specialist may find the simulation tools useful to design high-performance torque controllers.

Although it is a powerful reference in its own right, when used in conjunction with the companion texts Fundamentals of Electrical Drives and Applied Control of Electrical Drives, this book provides a uniquely comprehensive reference set that takes readers all the way from understanding the basics of how electrical drives work, to deep familiarity with advanced features and models, to a mastery of applying the concepts to actual hardware in practice.

·         Provides an overall understanding of all aspects of AC electrical drives, from the motor and converter to the implemented control algorithm, with minimum mathematics needed

·         Demonstrates how to implement and debug electrical drive systems using a set of dedicated hardware platforms, motor setup and software tools in VisSim™ and PLECS™

·         No expert programming skills required, allowing the reader to concentrate on drive development

·         Enables the reader to undertake real-time control of a safe (low voltage) and low cost experimental drive

This book helps students and engineers appreciate and understand the fundamental concepts of the modern electrical drives used in thousands of applications, from robotics and household appliances to wind turbines and hybrid vehicles. Updates to this second edition cover innovations in machine design, power semi-conductors, digital signal processors and simulation software. An interactive learning approach is taken in this text: theory and calculations are augmented by generic models which are transposed to a simulation platform. This ''build and play'' method visualizes the dynamic operation of a comprehensive set of modules ranging from an inductance to a novel ''ideal rotating transformer'' (IRTF). This module is at the center of the generic models used to explore the dynamic and steady state operation of grid and converter fed induction, synchronous and DC machines. The section on modulation and control emphasizes the role of power electronics and digital signal processors in drives. All figures in this text are included in the downloadable files in order to help with the preparation of customized Power Point type lecture material. Fundamentals of Electrical Drives is perfect for readers with basic engineering knowledge who have a need or desire to comprehend and apply the theory and simulation methods utilized by drive specialists throughout the world.
