1. 11. Closed-loop control and data- recording of a modular-multilevel converter (MMC)

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Longgang Su; [2022]
   Keywords : Modular multilevel converters MMCs ; filed programmable gate array FPGA ; direct memory access DMA ; energy closed-loop control; data recording; ethernet.; Modulära multilevel-omvandlare MMC ; filed programmeable gate array FPGA ; direkt minnesåtkomst DMA ; energistyrning med sluten slinga; datainspelning; ethernet.;

   Abstract : Modular multilevel converters (MMCs) are the preferred converter solution in flexible ac transmission systems (FACTS) and high-voltage direct current (HVDC) applications. This is due to the high quality of the voltage and current signals, lower overall losses, and fewer problems with switching-related EMI. READ MORE
