Abstract


The evaluation of Switched-Capacitor-Based Multilevel Inverters (SCMLIs) involves the use of a 'cost function' (CF) that incorporates key parameters such as devices count, total standing voltage (TSV), and source requirements.  In this study, a nine-level inverter is designed with the goal of achieving a minimal CF value and a reduced switch count while enhancing its boosting capabilities. This inverter achieves voltage amplification by efficiently regulating the series-parallel conversion of power supply and capacitors.  Unlike similar SC-based configurations, the proposed topology eliminates the need for a back-end H-bridge, effectively reducing voltage stress on switches and ensuring compatibility with the source voltage. A thorough comparative analysis of existing topologies is undertaken to illustrate the superior performance of the suggested structure in addressing essential aspects.  The proposed topology is investigated using level-shifted pulse width modulation strategy.  Additionally, it incorporates switched capacitor design and estimation of power losses in devices. Thermal modelling utilizing PLECS is employed to assess power losses and efficiency. The performance of configuration that is proposed is initially analyzed through MATLAB/Simulink simulations, accommodating diverse parameter modifications. Then, hardware-in-loop (HIL) experiments are conducted to validate the practicality of the research and the functionality of the proposed topology
