Abstract: Abstract This paper presents a design of modular multilevel inverter (MMI) using multicarrier PWM (MCPWM) techniques to improve the power quality. The proposed research work explores with the solar fed single phase eleven level inverter and modeling of MCPWM. MMI is designed and developed by employing the modulation techniques for generating the higher output voltage amplitude with several output levels. MCPWM is used for generating switching pulses for the proposed 11-level inverter. The level shifting MCPWM technique is used in this work to investigate a multilevel inverter with equal DC sources. The modeling of modulation approaches is set up in MATLAB/Simulink, and the same findings are tested experimentally to establish the schemes' practicality.
