Abstract: The object of this paper is to compare the five level three lags multilevel inverter with three level three lags multilevel inverter to control induction motor & reduce the Total harmonic distortion. The conventional two level inverter is not producing the high ac output voltage & also increases the higher torque pulsation, ripple factor, higher total harmonic distortion. The high AC output voltage, less torque pulsation, less ripple factor ,less total harmonic distortion is achieve with the help of multilevel inverter, so it is likely to raise the level of inverter. Filter is also play a vital role in reduction of Total harmonic distortion. Second order low pass filter & Lc filter are used in this project. Sinusoidal Pulse Width Modulation. Control scheme is proposed for 5 & 3 level 3 lags multilevel inverter. The simulation results shows that as level increases the efficiency of the system is also increases.
