Filling the gap in the market dedicated to PLL structures for power systems
Internationally recognized expert Dr. Masoud Karimi-Ghartemani brings over twenty years of experience working with PLL structures to Enhanced Phase-Locked Loop Structures for Power and Energy Applications, the only book on the market specifically dedicated to PLL architectures as they apply to power engineering. As technology has grown and spread to new devices, PLL has increased in significance for power systems and the devices that connect with the power grid. This book discusses the PLL structures that are directly applicable to power systems using simple language, making it easily digestible for a wide audience of engineers, technicians, and graduate students.
Enhanced phase-locked loop (EPLL) has become the most widely utilized architecture over the past decade, and many books lack explanation of the structural differences between PLL and EPLL. This book discusses those differences and also provides detailed instructions on using EPLL for both single-phase applications and three-phase applications. The book’s major topics include:
- A basic look at PLL and its standard structure
- A full explanation of EPLL
- EPLL extensions and modifications
- Digital implementation of EPLL
- Extensions of EPLL to three-phase structures
Dr. Karimi-Ghartemani provides basic analysis that helps readers understand each of the structures presented without requiring complicated mathematical proofs. His book is filled with illustrated examples and simulations that connect theory to the real world, making Enhanced Phase-Locked Loop Structures for Power and Energy Applications an ideal reference for anyone working with inverters, rectifiers, and related technologies.
In light of major ongoing restructuring in the power system and theproliferation of new devices, Karimi-Ghartemani summarizes his experience from working with different phase-locked loop structuresfor power and energy applications. He discusses the applications of grid-tie inverters in detail due to the growing interest in thistechnology, but does not otherwise focus on any particular application. Readers are assumed to be graduate students,applications engineers, and researchers. The book could also be used as a textbook for an advanced special-topic course at the graduate level. He avoids complication ed mathematical proofs.Annotation ©2014 Ringgold, Inc., Portland, OR (protoview.com)
Many excellent books covering phase-locked loops (PLLs) have been published; however, there is practically no book that covers the specifics of PLLs as employed in power systems. The usefulness for such a book fills an immediate need. Existing books cover the type of PLLs used in electronics, communications and instrumentation. Over the past decade or so, many new PLL structures have been developed to address the new requirements in modern power systems. The enhanced phase-locked loop (EPLL) is arguably the most widely accepted structure developed to address power system requirements. It is now a mature concept and has been developed in multiple forms and to address many applications. Due to the structural differences as well as the differences in applications requirements that exist between the “PLL” and the “EPLL”, existing books do not offer sufficient material to understand and employ the EPLL. The aim of the proposed book is to fill this gap and to provide a book that clearly, and in simple language, explains the EPLL and reviews its multiple forms and variety of its applications.
