A New Reduced Number of Components-Based Voltage Boosting Multilevel Inverter

Abstract—

The first significant contribution made by this article is a novel configuration for MLI that has the potential to enhance voltage. Second, this article’s MLI cuts down on the number of components, such as capacitors, switches, diodes, and DC sources. In addition to this, it describes symmetric and asymmetric configurations of DC sources, and the voltage boosting multilevel inverter (VBMLI) will generate 9-level and 17-level output voltages, respectively. The maximum number of levels may be generated by the VBMLI algorithm using either of two extended topologies that each include the necessary mathematical formulas for distinct parameters. To verify the functionality of the proposed 17-level VBMLI, experimental- and simulation-based findings are provided here.
