Capacitor voltage balance control strategy based on MMC-MTDC
E3S Web of Conferences, 2022 The MMC is composed of a large number of sub-modules. The operating conditions of each sub-module are different, which will inevitably affect the capacitor voltage of each sub-module, resulting in the difference of the capacitor voltage of each sub-module.

Capacitor balancing controller voltage sorting statistics in modular multilevel converters [PDF]
2017 IEEE Southern Power Electronics Conference (SPEC), 2017 Modular multilevel converters (MMCs) are made up of many submodules (SMs) connected in series. In order to avoid semiconductor over-voltages, SM capacitors should be kept within strict voltage limits. The capacitor balancing controller (CBC) is used to sort SM capacitor voltages prior to modulation.
