Abstract

In this proposed paper, a novel nine-level inverter (NLI) topology is proposed, which uses fewer components to provide nine voltage levels in the output. Ten semiconductor switches, four capacitors, and one dc voltage source are included in this NLI. Through various logical arrangements of the dc source and capacitors and the use of power semiconductor switches, the nine voltage levels are generated. In this case, only two switches can conduct simultaneously in any mode. As a result, the system's efficiency is increased and conduction losses are decreased. The low total standing voltage (TSV) of the power semiconductor switches is another crucial aspect of this design. Gate signals are produced using a suggested modulation approach to lessen the power switches' switching loss. Several Simulink simulations are run in order to validate the NLI. The suggested inverter has a much lower requirement for components and dc sources as compared to conventional topologies. In order to increase the efficiency of the power generating process in renewable energy systems, the proposed NLI structure can be implemented.
