Unidimensional modulation technique for cascaded multilevel converters. IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS, 56 (8), 2981-2986.0278-0046https://hdl.handle.net/11441/85869This 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 to determine the switching sequence and the corresponding switching times. In addition, a simple strategy to control the dc voltage ratio between the H-bridges of the multilevel cascaded converter is presented. Examples for the two-cell topology are shown but the proposed technique can be applied to develop modulation methods for a higher number of H-bridges. Experimental results are presented to validate the proposed technique.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/ModulationH-bridge convertersMultilevel cascadedinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1109/TIE.2009.20165106529313
