Experimental Implementation of new N-level Single-phase Multilevel Inverter

Abstract

Sinusoidal nature of inverter output voltage reduces the harmonic content thus enables the effective and efficient power conversion in various industrial drive applications. Multilevel inverter conquers the overall market over conventional inverters by an additional feature of non-filter requirement. Researchers are looking forward to minimize the overall components of the multilevel inverters. A new and novel inverter is projected in this paper with the least possible number of components mainly focuses to reduce the power switches thus to minimize the complexity, cost and space of the complete system. Proposed inverter is generalized in structure and can be used for same or different magnitudes of available DC sources. A 7-level as well as 13-level inverter is designed for the proposed topology and the real-time results verifies the simulation results thereby validates the feasibility of the inverter. Moreover, the proposed work is tallied with some newly invented topologies with reduced components.
