Abstract

Multilevel converters (MLCs) have been widely applied in fields such as high-voltage direct current (HVDC) transmission, electric vehicles, and wind power generation due to their advantages in improving power quality, reducing harmonics, and high-power applications. However, due to the influence of switching losses on system efficiency and thermal management, how to effectively suppress switching losses has always been a hot research topic. This paper reviews the research progress of switching loss suppression in multilevel converters in recent years, focusing on the following aspects: firstly, reducing switching losses by optimizing switching frequency and control strategy, such as low-frequency modulation technology and repetitive control; secondly, the proposal of new converter topology structures, such as modular multilevel converter (MMC) and hybrid multilevel converter (Hybrid MLC); thirdly, the combination of switching loss suppression methods and current circulation control techniques. Finally, this paper summarizes the challenges in current research and outlines the future research trends in switching loss optimization of multilevel converters.
