Abstract
In Low Voltage (LV) and Medium Voltage (MV) networks, specific power converters, namely the modular multilevel converters (MMC), need to be in-place to aggregate the renewable energy sources and provide an interface to the distribution electric network (grid). In addition, these multilevel converters can also be used as point-to-point interface in HVDC transmission networks. This paper presents an overview of the evolution of the modular multilevel converters. It lists the control strategies used for these types of converters. It presents the merit of the selecting the Subharmonics SPWM technique as the preferred techniques base on the harmonics cancellations inherent in the control method. A complete analysis of a 9-level MMC has been conducted and simulation results have been provided to verify the effectiveness in choosing the voltage balancing control in conjunction with the SPWM technique.
