Sneak Circuits of Power Electronic Converters Sneak Circuits of Power Electronic Converters Work on sneak circuits and related analysis methods for power converters contributes to the reliability of power electronic systems worldwide. Most books on the subject focus on electronic systems; this book is perhaps the first to examine power electronic systems. The authors describe sneak circuit phenomena in power converters, introduce SCA methods for power electronic systems, and propose how to eliminate and make use of sneak circuits. This book: highlights the advanced research works in sneak circuit analysis by a leading author in the fieldis original in its treatment of power electronics converters, going beyond the electronic system levelis suitable for both introductory and advanced levelsoffers guidelines for industry professionals involved in the design of power electronic systems, enabling early detection of potential problemsThis book is geared for researchers and graduate students in electrical engineering, as well as engineers and researchers in power electronics. Researchers in power electronics reliability will also find it to be a helpful resource.

An all-in-one guide to high-voltage, multi-terminal converters, this book brings together the state of the art and cutting-edge techniques in the various stages of designing and constructing a high-voltage converter. The book includes 9 chapters, and can be classified into three aspects. First, all existing high-voltage converters are introduced, including the conventional two-level converter, and the multi-level converters, such as the modular multi-level converter (MMC).  Second, different kinds of multi-terminal high-voltage converters are presented in detail, including the topology, operation principle, control scheme and simulation verification.  Third, some common issues of the proposed multi-terminal high-voltage converters are discussed, and different industrial applications of the proposed multi-terminal high-voltage converters are provided. Systematically proposes, for the first time, the design methodology for high-voltage converters in use of MTDC grids; also applicable to constructing novel power electronics converters, and driving the development of HVDC, which is one of the most important technology areasPresents the latest research on multi-terminal high-voltage converters and its application in MTDC transmission systems and other industrially important applicationsOffers an overview of existing technology and future trends of the high-voltage converter, with extensive discussion and analysis of different types of high-voltage converters and relevant control techniques (including DC-AC, AC-DC, DC-DC, and AC-AC converters)Provides readers with sufficient context to delve into the more specialized topics covered in the bookFeaturing a series of novel multi-terminal high-voltage converters proposed and patented by the authors, Multi-terminal High Voltage Converters is written for researchers, engineers, and advanced students specializing in power electronics, power system engineering and electrical engineering.
