A Novel Asymmetrical Multilevel Inverter with Reduced Number of Switches Regulated by PD-PWM Method

Over time, MLI have shown to be invaluable in a wide range of energy applications. Researchers are working on a few projects, such as designing topologies with fewer switches, optimizing performance in particular domains, investigating novel applications, and enhancing multilevel converter control. The number of levels and topology selected are directly influenced by output harmonics, with the condition that THD% be extremely near to zero. An innovative MLI asymmetric tension source converter topology with fewer components is presented in this research. Our approach, which uses the PD-PWM technique to regulate an output at 55 levels, is based on a thorough simulation carried out in the MATLAB Simulink environment. The outcomes are compared to other topologies with the same number of levels. To enhance the output tension quality, a pass-through filter is incorporated, allowing the THD% to be reduced to 0.92%. There are several benefits to this strategy of reducing the number of interrupters while increasing performance, including easier control, lower costs, increased reliability, and higher output quality.
