Modular multilevel converters (MMC) have become an attractive solution for high voltage direct current (HVDC) transmission applications due to its scalability, reliability and easy maintenance. Considerable work has been around the conventional 2-level half-bridge submodule. Use of multilevel submodules can result in smaller overall footprint, reduced components and lower losses. This paper presents...
The Modular Multilevel Converter (MMC) is a promising converter choice for Medium Voltage DC (MVDC) distribution systems, where SiC devices can be readily adopted taking full advantage of this semiconductor's properties. Specifically, 1.7 kV SiC MOSFETs are used to build 1kV modules operating at 100 kHz, thus eliminating the need to use multiple modules to generate a high equivalent switching frequency...
The modular multilevel converter (MMC) is a competitive candidate for VSC-HVDC systems. However, an account of various Sub-Modules bring serious difficulties for the appropriate operation principle design and performance analysis. This paper proposes the unified model of Half Bridge-MMC (HB-MMC) and MMCs with DC fault ride-through capability. Based on the operation essence of the cascaded rectifier...
