چکیده
In this paper presents a symmetrical five level cascaded inverter topology for Induction motor drive. It can continuously works at lower power stage. For this symmetrical circuit, when the number of level is increased, the voltage and power will also get increased. For reducing harmonics the Sinusoidal PWM method is used. The multilevel inverter gives the output to drive the three phase Induction motor .Its overall system performance is developed by employing multilevel inverter. It increases the act of the entire system in terms of harmonics and tension in the bearings of a motor. The torque ,phase voltage and speed characteristics are observed. The THD for different modulation index is estimated. The power factor is increased. The simulation of the circuit is attained by using MATLAB/simulink.
