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 ...

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.

A simple DC-Link Voltage Balancing Strategy for NPC Three-level Inverters
2023 25th European Conference on Power Electronics and Applications (EPE'23 ECCE Europe), 2023 Three-level neutral point clamped PWM inverters overcome some limitations of two-level inverters in medium voltage applications, leading to lower device ratings and greater efficiency. However, they are burdened by an intrinsic drawback of the neutral point clamped structure, which causes, under some operating conditions, a voltage imbalance of the DC ...

Active Voltage Balancing of Integrated Modular Drive with Series DC-Link Capacitors
2020 IEEE Energy Conversion Congress and Exposition (ECCE), 2020 In order to reduce the size and weight of transmission cables, high direct current (DC) bus voltage is desired for electrical machine drives used in the hybrid powertrains of more-electric aircraft (MEA). An integrated modular machine drive (IMMD) with DC-link capacitors connected in series is adopted to break down the supply voltage for each drive ...
