摘要

本文提出了一种新的模块化多电平变换器(MMC)调制方法，该方法思想简单，易于实现。它包括玩弄每个相位的相对行为，以获得所需的交流电压。这种方法还保证了每个子模块中的电压电容器保持恒定。此外，该转换器允许系统在不平衡条件下运行，并且如果使用全桥子模块，它本质上可以用作直流断路器(DC- cb)，而不需要额外的电力电子设备和控制。

A new control for modular multilevel converters and their use as DC circuit breaker

This paper presents a new modulation for modular multilevel converters (MMC) based on a simple idea, which is very easy to implement. It consists of playing with the relative behaviour of each phase in order to obtain the desired AC voltage. This method also assures that the voltage capacitor in each sub-module remains constant. Moreover, this converter allows the operation of the system under unbalanced conditions, and it can be used intrinsically as a DC circuit-breaker (DC-CB) without the need for additional power electronics and control if full bridge sub-modules are used.
