To optimise the efficiency of electric drives it is necessary to consider the components; the power electronic converter, the electric machine and the gearbox, together. Integrated systems can be smaller and have better flexibility and thermal management. Integrated motor drives (IMDs) specifically offer advantages including lower cost of installation and higher power density. This integration concept has been adopted in various electrical machine drive systems as well as electric vehicles.Integrated Motor Drives presents the state of research and future trends in integrated electrical motor drive technology and helps readers fill gaps in their knowledge. Chapters cover electrical machines, power converters and control techniques, adoption of wide bandgap semiconductor switching devices, thermal management, passive devices, gearboxes, research prototypes and commercial products, as well as emerging technologies and needs.This book for electrical motor drive engineers and researchers in academia and industry, as well as advanced students and experts, is systematically written by members from leading working groups. Close collaboration between chapter authors improves cohesion and usability for advanced students.

This book addresses the latest findings on practical ultra-high voltage AC/DC (UHVAC/UHVDC) power transmission. Firstly, it reviews current constructions and future plans for major UHVDC and UHVAC projects around the world. The book subsequently illustrates the basic theories, economic analysis, and key technologies of UHV power networks in detail, and describes the design of the UHVAC substations and UHVDC converter stations and transmission lines. A wealth of clear and specific figures and formulas help readers to understand the fundamental theories underlying UHVAC and UHVDC technologies, as well as their developmental trends. This book is intended for graduate students, researchers and engineers in the fields of power systems and electrical engineering.
