直流侧周期性功率需求下的模块化多电平变换器

The operation of modular multilevel converters (MMCs) with a periodic dc-side voltage is considered whose fundamental frequency component is linked to the grid frequency. Such a voltage component arises for instance by operating a pulsed power load, which is analyzed in this article as an example for this problem class. This application entails harmonic voltage components, which in conjunction wit...
