Voltage Balancing Control of Diode-Clamped Multilevel Inverter [PDF]
Journal of Electrical and Electronics Engineering, 2013 In this paper is developed a control scheme for mono-phase diode clamped inverter to achieve balancing voltages on inverter capacitors. First, it develops a control scheme without taking into account the need to balance voltage on two capacitors.

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.

Improved natural balancing with modified phase shifted PWM for single-leg five-level flying-capacitor converters [PDF]
, 2012 Flying capacitor converters (FCCs), as most multilevel converter topologies, require a balancing mechanism of the capacitor voltages. FCCs have the valuable property of natural voltage balancing when a special modulation technique is used.
