In this paper, an advanced configuration for a symmetric multilevel voltage source inverter is proposed. The authority of the proposed inverter versus the conventional cascaded H-bridge inverter and those most recently introduced is verified with provided comparisons. The proposed inverter is able to generate the desired voltage levels using a lower number of circuit devices, including power semiconductor switches and related gate driver circuits of switches. As a result, the total cost is considerably reduced, and the control scheme gets simpler. Moreover, the reduced amount of on-state switches in the suggested configuration decreases voltage drops. Furthermore, power losses are diminished. The given simulation results confirm the feasibility of the proposed configuration. To approve the practicability of the proposed inverter, a prototype of the proposed topology has been implemented. Finally, simulation and experimental results are compared, and the provided comparison shows that the obtained results are in good agreement.
