In high power applications nowadays multilevel voltage source inverter provides alternative to theconventional two level voltage source inverter. Using this multilevel technique, switching devices losses and stress isreduced, the output voltage amplitude is increased and improved overall harmonic profile can be achieved. Thisadvantages helps to reduce the size of passive filters. This paper focuses on cascaded h-bridge multilevel inverter usingamplitude modulation technique which minimizes number of sources and power semiconductor devices. Simulation of 13level inverter is done using MATLAB Simulink software with and without amplitude modulation technique and results arecompared. Further a 41 level inverters is also simulated using amplitude modulation technique and Fourier analysis isdone for total harmonic distortion.
