A paper detailed investigation of the operating dynamics of a multilevel inverter is presented in this research using MATLAB simulation. The inverter architecture consists of eight switching units that combine unidirectional and bidirectional components. Two distinct designs are analysed to assess their performance characteristics: symmetrical and asymmetrical. Simulation yields the highest output voltages for the symmetrical configuration and Voltage for the asymmetrical design. Hence, the research employs Multiple Carrier Pulse Width Modulation (MCPWM) techniques to achieve this high voltage levels. The findings demonstrate the efficiency of the proposed multilayer inverter architecture and the strategic application of MCPWM to minimize harmonic distortions and provide high-voltage outputs.
