This project presents the simulation of “transformer based cascaded multilevel inverter with reduced number of
switches” with R-load and. It has the advantages of reduced number of switches and dc sources compared to conventional
configurations and consequently higher efficiency. The simulation is accomplished for one stage (3-level), two stage (5-level, 7-
level, 9-level), three stage (7-level, 11-level, 15-level, 19-level, 27-level) and four stage (29-level, 31-level, 33-level, 35-level). And
their performance is analysed in terms of THD (Total Harmonic Distortion) for output voltages and currents. The FFT (Fast
Fourier Transform) analysis is used in order to evaluate the harmonic distortion. The simulation is carried out by using
MATLAB/SIMULINK software.
