Enhanced DC-Link Capacitor Voltage Balancing Control of DC–AC Multilevel Multileg Converters
IEEE Transactions on Industrial Electronics, 2015 This paper presents a capacitor voltage balancing control applicable to any multilevel dc-ac converter formed by a single set of series-connected capacitors implementing the dc link and semiconductor devices, such as the diode-clamped topology. The control is defined for any number of dc-link voltage levels and converter legs (for single-phase and ...

Active voltage balancing of DC-link electrolytic capacitors
IET Power Electronics, 2008 DC voltage links of three-phase power converters are frequently equipped with a series connection of two electrolytic capacitors because of high voltage level. For such a configuration, usually resistors have to be arranged in parallel to each capacitor in order to balance the partial voltages. These balancing resistors, however, have to be dimensioned

DC link capacitor voltage balancing in three level neutral point clamped inverter [PDF]
2012 IEEE 13th Workshop on Control and Modeling for Power Electronics (COMPEL), 2012 Multilevel inverters are becoming increasingly popular for high and medium power applications. The diode clamped multilevel inverter (DCMLI) is an attractive high voltage multilevel inverter due to its robustness. The deviating voltage at the neutral point remains always a distracting feature in NPC inverter.
