Abstract
Modular multilevel converter (MMC)has been widely applied into HVDC,power quality control,electric drive and other fields due to its characteristic of modular topology of common DC bus.Topology structures of MMC were introduced,and then mathematical models of MMC were established as well as its regulation of operation control.The mechanism,quality and functions of circulation formation were analyzed.The relationship between current of bridge arm and circulating current was deduced.The model predictive control strategy of MMC was analyzed and the experimental results show that sub-module capacitor voltage is balanced and the circulating current amplitude is decreased effectively under the adopted control strategy.关键词
