Abstract

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