Full-bridge modular multilevel converter (FB-MMC) with extended control range [PDF]
AFRICON 2015, 2015 This paper presents an attractive control scheme that decouples cell capacitor voltage regulation of the FB-MMC from the dc link voltage regulation. This is achieved by manipulating both ac and dc components of modulation functions. The dc component of modulation function is used to regulate the cell capacitor voltages independent of the dc link ...
