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 ...
