The reliable and consistent operations of modular multilevel converters (MMCs) under fault conditions are crucial for high-voltage and high-power applications. To strengthen the performances of MMCs under submodule (SM) faults, a fault- tolerant stra

Due to the large number of submodules (SMs), and modular multilevel converters (MMCs) in high-voltage applications, they are usually regulated by the nearest level modulation (NLM). Moreover, the large number of SMs causes a challenge for the fault d

Dead time is necessary for the coupled power switches to prevent shoot-through, especially in the modular multilevel converters (MMCs) with a large number of power switches. This paper proposes a dead-time effect suppression strategy for MMCs with ne

Abstract In the case of grid voltage quality problems, the traditional phase‐locked loop (PLL) is hard to detect the accurate grid frequency and phase during the transient response, which will be detrimental to the transient synchronous stability o
