_a"This book focuses on fault detection, protection, and tolerant control of modular multilevel converters (MMCs) under two kinds of faults: internal faults (IGBT and capacitor faults), external faults (AC-side grid faults and DC-side grid faults). It begins with a description of MMCs' configuration, operation principle, modulation scheme, mathematical model, and component design. It then introduces output control, centralized capacitor voltage-balancing control, individual capacitor voltage-balancing control of MMCs. The book proceeds to explore fault detection of the MMC under IGBT faults before moving on to discuss the capacitor monitoring and control of MMCs under capacitor faults. Later chapters describe fault tolerant control of MMCs when the faulty SM is bypassed, control of MMCs under ac grid faults, and protection of MMCs under DC line short-circuit faults"-- _cProvided by publisher. |
