Opis

Recent advances in the area of power electronics have resulted in a great variety of new topologies and control strategies for active filters and UPS systems. This book addresses these new trends in detail. The authors present an in-depth discussion of similarities and differences between active filters, UPS systems, and unified power quality conditioners, with an emphasis on low-cost, reduced-parts configurations not included in any other publication. The book also includes an easy-to-understand description of active filters including basic conventional and modern topologies, including many new topologies, and a comprehensive presentation of uninterruptible power supplies.

Recenzje

"It is an attractive reference book for research and development engineers who are interested in modern wind energy systems design and control. Also, it can be useful for [an] advanced senior-level course … ."
