Static VAR compensators (SVC), power rectifiers, and thyristor converters are examples of power electronics components that significantly contribute to harmonics in a range of applications. The use of power electronic converters, especially DC/AC PWM inverters, has been expanding in the industry due to the advantages they provide, including reduced energy consumption, improved system efficiency, higher-quality products, simplicity of maintenance, and more. One of the most basic and well-known topologies for multilevel inverters is cascaded H-Bridge (CHB) MLI. A KY boost converter with seven-level inverters is suggested in this study. A Matlab simulation is used to evaluate the suggested work. According to the simulation findings, the output voltage climbed from 121V to 155V, the motor speed increased from 940 rpm to 1050 rpm, the motor torque increased from 0.92 N/m to 1.80 N/m, and the output current THD decreased from 31.2% to 19.01% when a KY boost converter with a seven-level inverter was used. According to the simulation results, the conventional boost converter with a five-level inverter system performs worse than the suggested KY boost converter with seven-level inverters.
