Abstract

Modular Multilevel Converters (MMC) have been widely applied in medium- and high-voltage applications such as High Voltage Direct Current (HVDC) Transmission. Hence, the modulation method which can generate low harmonic waves with low losses is quite suit for the HVDC condition. This paper proposes a new nearest level modulation (NLM) method for the MMC, with which can decrease the harmonic components. Using this method, the level number of the MMC is almost doubled and the height of the step in the step wave is halved. The performance of the proposed method is verified by simulations with the PSCAD/EMTDC software.
