TL;DR: In this article, a general implementation of the phase-shifted carrier (PSC) modulation with a capacitor voltage balancing method for MMC is first introduced, and the mathematical analysis of PSC modulation for the modular multilevel converter (MMC) is performed to identify the PWM harmonic characteristics of the output voltage and the circulating current.

TL;DR: In this article, a fault diagnosis and tolerant control solution, including the fault detection, fault tolerance, fault localization, and fault reconfiguration, have been proposed to ride through the insulated gate bipolar transistor open-circuit failures.

TL;DR: An improved circulating current injection method is proposed, which does not completely eliminate the capacitor voltage ripple, but maintains it bounded within reasonable values, leading to converter efficiency improvement and reduction of semiconductor current ratings.

TL;DR: In this article, a hybrid MMC topology is introduced, which significantly reduces the voltage ripple of capacitors, particularly at low motor speeds, and this topology does not introduce any motor common-mode voltage; as a result, there are no insulation and bearing current problems.

TL;DR: In this paper, a transformerless static synchronous compensator (STATCOM) system based on multilevel H-bridge converter with star configuration is presented, where a nonlinear controller based on the passivity-based control theory is used in this cascaded structure STATCOM for the first time.
