Performance Analysis of Thirty-one Level Multilevel Inverter for Electric Vehicle Application

Abstract

This research provides a new architecture for reduced component count 31-level multilevel inverter (MLI). The suggested design uses four unequal DC sources and an H-bridge to provide a maximum 31-level output voltage. For applications using renewable energy, the topology designed for the 31-level can be employed. This lowers the system's total cost, number of components, and size. Higher level counts for lower total harmonic distortion (THD), however, dependability concerns are more significant than MLIs' many benefits. Total standing voltage (TSV), cost function (CF), and power loss are the various metrics that are examined for 31-level MLI. Experiments with different combinational loads and dynamic load fluctuations with sudden load disturbances are performed to assess the inverter's performance. The cost-effectiveness of the suggested MLI is demonstrated while comparing its TSV with the cost function against other topologies that have been recently published.
