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 ...
