Cascade multilevel inverter (CMI) is the most efficient option for medium-voltage, high-power applications. Higher than usual interest is being paid to CMI in comparison to the more commonplace two-level inverter because of its reduced voltage pressure on the switching electronics, higher harmonic performance, and better voltage quality. The technique of pwm technique, commonly known as PWM, has been the focus of extensive research for quite some time. Multi carrier pulse width modulation (MCPWM) technology is used to improve the harmonics performance of a cascade multilayer inverter. In this paper, we examine the theoretical foundations of spread spectrum PWM strategies and use a computational simulation to contrast the various implementations. CMI’s unique features allow it to be used in many situations. In this research, we focus on the most significant uses of CMI.
