Asymptotic rejection of sinusoidal disturbances based voltage balance control in back-to-back power converters
(2014)
This paper addresses the imbalance problem of the dc-link capacitor voltages in the three-level diode-clamped back-to-back power converter. In order to cope with it, a mathematical analysis of the capacitor voltage difference ...

A controller for practical stability of capacitor voltages in a five-level diode-clamped converter
(Elsevier, 2016-09)
The balancing of the dc-link capacitor voltages represents the main technical challenge in multilevel diode-clamped converters. In particular, when the number of capacitors is greater than two, these power conversion systems ...
