Advantages of the modular multilevel converter (MMC) such as modularity, scalability, fault-tolerant ability, low device switching frequency, transformerless grid connection etc. have made it the most promising converter topology for medium-tohigh-voltage, high-power applications. However, in MMC-based medium-voltage drives, the excessive fundamental-frequency submodule capacitor voltage ripple at low speeds or start-up poses a major technological challenge. A lot of low-frequency ripple suppression methods have been proposed to address this problem. This study summarises the state of the art in this area and classifies these methods into three categories. The pros and cons of them are discussed. An in-depth analysis of these methods from a practical viewpoint is given. Some future research trends are also discussed.

“…In recent years, these initiatives have resulted in the installation of utility-scale wind and solar farms. The operations of such MW-scale plants require high-voltage/-power multilevel inverters (MLIs), and as a result, the usage of MLIs has proliferated [1,2]. MLIs can be categorized into three main types: neutral-point-clamped (NPC) [2,3], flying-capacitor (FC) [4,5] and cascaded H-bridge (CHB) topologies [6][7][8][9].…”

Abstract:The increasing integration of large solar PV and wind farms into the power grid has fueled, over the past two decades, growing demands for high-power, high-voltage, utility-scale inverters. Multilevel inverters have emerged as the industry's choice for megawatt-range inverters because of their reduced voltage stress, capability for generating an almost-sinusoidal voltage, built-in redundancy and other benefits. This paper presents a novel switched-source multilevel inverter (SS MLI) architecture. This new inverter shows superior capabilities when compared to existing topologies. It has reduced voltage stress on the semiconductor, uses fewer switches (i.e., reduced size/weight/cost) and exhibits increased efficiency. The proposed SS MLI is comprised of two voltage sources (V 1 , V 2 ) and six switches. It is capable of generating five-level output voltage in symmetric mode (i.e., V 1 = V 2 ) and seven-level output voltage in asymmetric mode (i.e., V 1 = V 2 ). We present simulations results (using MATLAB R /Simulink R ) for five-and seven-level output voltages, and they strongly support the validity of the proposed inverter. These positive results are further supported experimentally using a laboratory prototype.
