The ‘Cost function’ (CF) study of Switched-Capacitor-Based Multilevel Inverters (SCMLIs) includes important characteristics such as device count, total standing voltage (TSV), and source demands. The purpose of this study is to enhance the boosting capabilities of a seven-level inverter by reducing its switch count and CF value. By effectively controlling the series-to-parallel conversion of the power source and capacitors, this inverter produces voltage amplification. This article presents a novel, one-dc source, seven-level inverter that is suitable for wind and solar power applications. Floating capacitors (FC) combined with a switched-capacitor design yields the desired outcome. This configuration was selected to minimize control problems when generating a tripolar staircase pattern because of its sensor-less capacitor voltage balancing potential. Inadvertent overvoltage of the capacitor is prevented over time, resulting in a further benefit. The phase disposition pulse-width modulation (PD-PWM) technique has been used to regulate the operation of the topology. Moreover, fewer semiconductor devices are utilized in the suggested topology. A detailed comparison of various recently-released seven-level inverter topologies is given to illustrate the advantages of the suggested layout for reducing switch count. Thermal modeling with PLECS is used to evaluate efficiency and power losses. MATLAB/Simulink and HIL implementation are used to explore the viability of implementing the suggested structure under various parametric restrictions.
