TL;DR: The development of MMC circuit topologies and their mathematical models over the years are presented and the evolution and technical challenges of the classical and model predictive control methods are discussed.

TL;DR: A survey on important electrical engineering aspects for PMSG-based megawatt-level wind energy conversion systems (WECS) and a comprehensive analysis on power converter topologies for wind turbines (WTs), grid integration of wind farms, digital control schemes, fault-ride-through compliance methods, and future trends is presented.

TL;DR: The importance of each challenge in an MPC and its impact on the system performance is discussed, and the MMC mathematical models used in the implementation of MPC are presented.

TL;DR: A dual space-vector pulse-width modulation (SVPWM) technique is proposed for an MMC, which eliminates the external controller for arm voltage balancing and uses the direction of load current instead of the arm current in SM selection process, which reduces the required number of current sensors in a three-phase system.

TL;DR: Four basic types of synchronized discontinuous PWM sequences that ensure synchronization, three-phase symmetry, and half-wave symmetry are presented that are compared with that of the conventional synchronized space vector PWM.
