Theoretical analysis and experimental validation of a novel multilevel inverter topology for renewable energy interfacing applications

Krishna Kumar Gupta and Shailendra Jain This paper presents a new topological structure for symmetrical cascaded multilevel inverters. The proposed circuit consists of cross-connected separate symmetrical DC sources which can generate number of levels equal to that of a cascaded H-bridge topology with reduced number of power switches. It ... [J. Renewable Sustainable Energy 4, 013113 (2012)] published Tue Feb 14, 2012.
