Arm-Balancing Control and Experimental Validation of a Grid-Connected MMC With Pulsed DC Load

Abstract

This paper focuses on the operation of a grid-connected modular multilevel converter (MMC) supplying a pulsed dc load. The goal is to achieve minimum ac power fluctuation despite the high power fluctuation present on the dc side. The MMC has been selected for its inherent ability to decouple ac and dc current controllers. However, if no additional… (More)
