An all-in-one guide to high-voltage, multi-terminal converters, this work brings together state-of-the-art and cutting-edge techniques in high-voltage converter design and construction. All existing high-voltage converters are comprehensively reviewed, including conventional two-level converters and multi-level converters, such as the modular multi-level converter "MMC". Different kinds of multi-terminal high-voltage converters are presented in detail, including the topology, operation principle, control scheme and simulation verification. Finally, some common challenges of the proposed multi-terminal high-voltage converters, such as the dc-side short-circuit fault handling and capacitor voltage balancing, are reviewed and different industrial applications of the proposed multi-terminal high-voltage converters are provided. . Systematically proposes high-voltage converter design methodology for use in multi-terminal direct current "MTDC" grids, novel power electronics converters, and the development of HVDC. Presents the latest research on multi-terminal high-voltage converters and its application in MTDC transmission systems and other industrially important applications. Offers an overview of existing technology and future trends of high-voltage converters, with analysis of different types of high-voltage converters and corresponding control techniques "including DC-AC, AC-DC, DC-DC, and AC-AC converters" Featuring a series of novel multi-terminal high-voltage converters proposed and patented by the authors, Multi-terminal High-voltage Converter is written for researchers, engineers, and advanced students specializing in power electronics, power system engineering and electrical engineering.
