Multilevel Inverters

Multilevel Inverters: Conventional and Emerging Topologies and Their Control is written with two primary objectives: (a) explanation of fundamentals of multilevel inverters (MLIs) with reference to the general philosophy of power electronics; and (b) enabling the reader to systematically analyze a given topology with the possibility of contributing towards the ongoing evolution of topologies. The authors also present an updated status of current research in the field of MLIs with an emphasis on the evolution of newer topologies. In addition, the work includes a universal control scheme, with which any given topology can be modulated. Extensive qualitative and quantitative evaluations of emer...

Mitigation of Negative Impedance Instabilities in DC Distribution Systems

  • Publisher: Springer

This book focuses on the mitigation of the destabilizing effects introduced by constant power loads (CPLs) in various non-isolated DC/DC converters and island DC microgrids using a robust non-linear sliding mode control (SMC) approach. This book validates theoretical concepts using real-time simulation studies and hardware implementations. Novel sliding mode controllers are proposed to mitigate negative impedance instabilities in DC/DC boost, buck, buck-boost, bidirectional buck-boost converters, and islanded DC microgrids. In each case, the condition for the large-signal stability of the converter feeding a CPL is established. An SMC-based nonlinear control scheme for an islanded DC microgrid feeding CPL dominated load is proposed so as to mitigate the destabilizing effect of CPL and to ensure system stability under various operating conditions. A limit on CPL power is also established to ensure system stability. For all proposed solutions, simulation studies and hardware implementations are provided to validate the effectiveness of the proposed sliding mode controllers.

Control of Power Inverters in Renewable Energy and Smart Grid Integration

Integrating renewable energy and other distributed energysources into smart grids, often via power inverters, is arguablythe largest “new frontier” for smart grid advancements.Inverters should be controlled properly so that their integrationdoes not jeopardize the stability and performance of power systemsand a solid technical backbone is formed to facilitate otherfunctions and services of smart grids. This unique reference offers systematic treatment of importantcontrol problems in power inverters, and different generalconverter theories. Starting at a basic level, it presentsconventional power conversion methodologies and then‘non-conventional’ methods, with a highly accessiblesumm...

Thyristor-Based FACTS Controllers for Electrical Transmission Systems

An important new resource for the international utility market Over the past two decades, static reactive power compensators have evolved into a mature technology and become an integral part of modern electrical power systems. They are one of the key devices in flexible AC transmission systems (FACTS). Coordination of static compensators with other controllable FACTS devices promises not only tremendously enhanced power system controllability, but also the extension of power transfer capability of existing transmission corridors to near their thermal capacities, thus delaying or even curtailing the need to invest in new transmission facilities. Offering both an in-depth presentation of theoretical concepts and practical applications pertaining to these power compensators, Thyristor-Based FACTS Controllers for Electrical Transmission Systems fills the need for an appropriate text on this emerging technology. Replete with examples and case studies on control design and performance, the book provides an important resource for both students and engineers working in the field.

  • Publisher: Springer

This book explores basic and applied aspects of microorganisms, which have a unique ability to cope with abiotic stresses such as drought, salinity and changing climate, as well as biodegrader microorganisms and their functional roles. Further, readers will find detailed information on all aspects that are required to make a microbe “agriculturally beneficial.” The book’s primary focus is on microbes that are essentially “hidden miniature packages of nature” that influence agro-ecosystems. Inviting papers by prominent national and international scientists working in the field of agricultural microbiology, it addresses the biogdegrader group of microbial inoculants. Each chapter cov...

Diagnostic Hysteroscopy

The diagnostic investigation of menstrual dysfunction and sterility is a routine part of gynaecological practice. Hysteroscopy can expand the spectrum of diagnostic possibilities. The 2nd revised edition of this handbook aims to familiarise the gynaecologist with diagnostical hysteroscopy. About 100 colour plates facilitate the acquisition of this technique as well as the correct assessment of findings. The book is conceived for newcomers to hysteroscopy and should contribute to the further establishment of this method. 2nd revised edition 90case studiesof gynaecological practice
