Abstract

The idea of a multiple inverter originated from the extension of inverters to many layers in order to lessen distortion from the basic sinusoidal waveform. Using multiple level inverters has the drawback of requiring the installation of extra switches, which raises the system’s bulk and cost and reduces its reliability due to the higher component count. This study proposes a twentyfive-level inverter (25-LI) with fewer switches to address the issue of the system being bigger, more expensive, less dependable, and having less distortion than a symmetrical H-bridged 25-level inverter. The MATLAB platform is used to develop the idea, and analysis is used to evaluate the results’ effectiveness.
