The contributions in this publication on electromagnetic fields in electrical engineering aim at joining theory and practice, thus the majority of the papers are deeply rooted in engineering problems and simultaneously present a high theoretical level. There are three chapters in this volume, all divided into seven subchapters. Papers gathered in the first chapter are mainly devoted to physics of electromagnetic materials and mathematical approaches to electromagnetic problems.

The next chapter contains papers dealing with numerical (or computer) analysis of electromagnetic devices and phenomena, whereas the last chapter reveals the world of engineering problems, showing how theoretical and methodological considerations can be transferred to real engineering problems. The editors hope that this book will help the world-wide electromagnetic community, both academic and engineering, in better understanding electromagnetism itself and its application to technical problems.

The development of power semiconductors with greater ratings and improved characteristics has meant that the power industry has become more willing to develop new converter configurations. These new configurations take advantage of the higher controllability and switching frequencies of the new devices. The next few years will decide which of the proposed technologies will dominate future power transmission systems.

Flexible Power Transmission is a comprehensive guide to the high voltage direct current (HVDC) options available, helping the reader to make informed decisions for designing future power transmission systems.

The book includes:
* a full description of the principles and components in existing converter technology, as well as alternative proposals for self-commutating conversion; A review of the state of power semiconductors suited to HVDC transmission and present proposals for multi-level HVDC transmission.
* a detailed overview of the flexible HVDC methods for improving controllability and increasing power transfer capability in electrical power systems.
* up-to-date information on thyrisistor-based HVDC technology.
* coverage of new pulse width modulation (PWM) transmission technology and multi-level voltage source conversion (VSC) and current source conversion (CSC).
