Abstract:Selective harmonic elimination (SHE) is a suitable pulse‐width modulation (PWM) technique for some applications of modular multilevel converters (MMC) with lower number of semiconductor submodules (SM). However, SHE can make it difficult to control circulating currents in the MMC. Moreover, the MMC is vulnerable to SM switch failures that reduce its output power magnitude and quality. This paper proposes a fault‐tolerant model predictive control strategy for MMCs operating with SHE (FT SHE‐MPC). The effects of… Show more
