Multilevel inverters perform power conversion in multiple voltage steps to achieve better power quality, lower switching losses, greater electromagnetic compatibility, and higher voltage capability. The multilevel inverter (MLI) provides high power capacity, with low output harmonics and low switching losses. In industries, multilevel inverters are widely applicable in a large number of applications. The paper proposes a new structure of multilevel inverter with low output harmonics. In this paper the number of switching devices is less than the conventional multilevel inverter. It consists of an H-bridge inverter that produces multilevel output voltage by switching DC voltage sources in series and parallel. This topology produces a significant reduction in the number of power devices. This topology reduces the number of main power switches by 44% compared to basic MLI topologies. This advanced topology generates a large number of voltage levels with the minimum number of switches. The proposed topology also reduces total harmonic distortion (THD...
