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 ...

Model predictive control with constant switching frequency using a discrete space vector modulation with virtual state vectors
(2009)
Finite states model predictive control (FS-MPC) appears as a promising control technique to be applied to power converters in the industry. However, the FS-MPC presents some drawbacks as non constant switching frequency ...

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 ...
