一种用于中压电机驱动的、具有最小化直流电容和变压器体积的新型模块化磁耦合变换器

The serious issues of massive transformer and bulky dc capacitors have not been solved for medium-voltage motor drives based on cascaded H-bridges (CHBs) and modular multilevel converters (MMCs). In order to overcome these issues, this article proposes a novel modular magnetic-coupled converter. It installs two sets of three-phase input and output H-bridges per module with their dc capacitors cros...
