DC-Voltage-Ratio Control Strategy for Multilevel Cascaded Converters Fed With a Single DC Source
(Institute of Electrical and Electronics Engineers, 2009)
Recently, a multilevel cascaded converter fed with a single DC source has been presented. An analysis of the steady-state working limits of this type of converter is presented in this paper. Limits of the maximum output ...

Multilevel Multiphase Feedforward Space-Vector Modulation Technique
(Institute of Electrical and Electronics Engineers (IEEE), 2010)
Multiphase converters have been applied to an increasing number of industrial applications in recent years. On the other hand, multilevel converters have become a mature technology mainly in medium- and high-power applications. ...

Unidimensional modulation technique for cascaded multilevel converters
(Institute of Electrical and Electronics Engineers (IEEE), 2009)
This paper presents a simple and low computational cost modulation technique for multilevel cascaded H-bridge converters. The technique is based on geometrical considerations considering an unidimensional control region ...

Feed-forward Space Vector Modulation for Single-Phase Multilevel Cascade Converters with any DC voltage ratio
(Institute of Electrical and Electronics Engineers (IEEE), 2009)
Modulation techniques for multilevel converters can create distorted output voltages and currents if the DC link voltages are unbalanced. This situation can be avoided if the instantaneous DC voltage error is not taken ...
