U. P. Lavanaya Department of Electrical and Electronics Engineering, Aditya University, Surampalem, INDIA P. Vinod Department of Electrical Engineering, Andhra University, Visakhapatnam, INDIA In this article, a novel seven-level inverter that performs on a single DC source and is suitable for solar and wind applications is described. By integrating floating capacitors (FC) using a switched-capacitor method, the desired outcome is produced. Due to its sensorless capacitor voltage balancing capability, which minimizes control concerns when generating a tripolar staircase pattern, this arrangement has gained recognition. Sustainable performance that prevents accidental capacitor overvoltage is another benefit. To regulate the topology's operation, a phase disposition pulse-width modulation (PD-PWM) technique has been used. Additionally, fewer semiconductor devices are used in the suggested topology. To demonstrate the positive aspects of the suggested structure regarding reducing the number of switches, a thorough comparison of various recently developed 7L inverter designs is given. Under various parametric constraints, the effective implementation of the suggested structure is examined using MATLAB/Simulink. The feasibility of the study and the functionality of the proposed topology are subsequently verified using hardware-in-loop (HIL) experiments. 12 30 2025 12 30 2025 278 29 https://creativecommons.org/licenses/by/4.0/deed.en_US 10.37394/23201.2025.24.29 https://wseas.com/journals/cas/2025/a585101-024(2025).pdf A.
