Cascaded H-bridge Multilevel Inverters -A Reexamination

2007 IEEE Vehicle Power and Propulsion Conference, 2007
Multilevel converters have gained popularity in high-power applications due to their low switch voltage stress and modularity. Cascaded H-bridge converters are a promising breed of multilevel converters which generally require several independent dc sources. Recently, existence of a redundant switching state has been utilized to replace the independent
