MMC的交流端口电压不是随便设计的，最主要取决于直流电压的设计（而直流电压的设计与工程输送容量和距离有关），同时也与子模块的数量、子模块额定电压等因素有关，因此MMC的交流端口额定电压并不一定与电网的某个电压等级相同，而换流变就用于将MMC的 ...

模块化多电平换流器 (modular multilevelconverter MMC)已成为柔性直流输电系统的首选换流器拓扑。 我国已建成的上海南汇柔性直流工程、南澳三端柔性直流工程、舟山五端柔性直流输电工程以及正在建设中的厦门柔性直流工程都采用MMC结构。

MMC稳态运行模式可以分为跟网型控制和构网型控制，二者的根本区别是电压相位的获取方式不同。 跟网型控制必须通过某种方式（通常为锁相环）得到电网电压相位，基于电网电压相位完成控制；构网型控制的电压相位则是控制器自身通过控制环节生成的。

2022年6月13日 · The modular multilevel converter (MMC) has become one of the most attractive converters for high-power applications such as high-voltage dc (HVDC) converters, but also fusion devices’ power supplies.

In materials science, a metal matrix composite (MMC) is a composite material with fibers or particles dispersed in a metallic matrix, such as copper, aluminum, or steel. The secondary phase is typically a ceramic (such as alumina or silicon carbide) or another metal (such as steel [1]).

Modularity, low losses, scalability as well as low filtering requirements make the Modular Multilevel Converter (MMC) a best solution besides HVDC implementatio

2016年2月1日 · In this study, a novel modular multilevel converter (MMC) topology for low-modulation applications is proposed. The proposed topology has two three-phase AC ports and is characterised by its bifurcate arms and phase-shifted connection on the AC side.

模块化多电平换流器（MMC）采用模块化设计，灵活配置，广泛应用于高压直流电压源换流器中。MMC具备不同的拓扑结构，可显著降低开关损耗，减少对滤波器的需求。其内部包含数百个子模块，通过精确控制实现高效电力转换。更多信息可访问英飞凌官微和 ...

2025年2月13日 · Female gametophyte development initiates from the megaspore mother cell (MMC), and only 1 somatic cell develops into an MMC. Here, we report that the balance between DNA methylation and demethylation ensures the maintenance of a single MMC in Arabidopsis (Arabidopsis thaliana).

2022年10月22日 · More specifically, a major emphasis is put on the modular multilevel converter (mmc s) by describing its topology, key features, pros and cons with respect to other converter technologies, as well as the reasons for its increasing popularity in the recent years.
