This research aims to develop a photovoltaic-based MLI that utilizes a pulse width modulation strategy as its mode of operation. In this particular example of a multilayer inverter, two switches are employed to enable the switching of the fundamental frequency and the carrier frequency. The initial three sections of this article delve into the analysis and discussion of the influence that different levels of carrier signal exert on inverters. Assess the impact it has on the voltage, current, and harmonics distortion. Assess the effect it has. Additionally, the study examines the impact of load variations on the output of the PV-based multilayer inverter and analyzes the resulting harmonic count. Yet another comparison was made between a seven-level inverter and a nine-level hybrid inverter, focusing on the use of a multilevel PV-based inverter. The aim was to reduce harmonic distortion, increase the output voltage, and analyze the impact on losses. This was a comparison that involved a seven-level inverter. Calculations and results obtained from a customized version of the MATLAB program suggest that the entire range of harmonics can be addressed by integrating level change technology with multi-stage hybrid inverters. These calculations and results were accomplished.
