The immense growth in Multilevel inverters are a great development for industrial and renewable energy applications due to their dominance over conventional two-level inverters concerning size, rating of switches, filter requirement, and efficiency. According to the current topology, the multilevel inverter employing the bidirectional converter is a DC connection that serves as the bidirectional inverter's input power. The bidirectional inverter is configured to output a voltage with several levels by altering the voltage with the bidirectional converter. Also, because there is no need for a low-frequency transformer or an LC filter at the output stage of the multi-level inverter in the present topology, the frequency does not pose any difficulties. In comparison to other traditional topologies, using an asymmetrical multilevel inverter architecture employs fewer switching components to create greater levels. This study proposes a 27-level multilevel inverter with fewer switching components. To validate the technique, the simulation results are shown.
