Now a day’s many industrial applications requires high power. Some other appliances may require intermediate power either more or less depending upon their operation. With these consequences, MULTI LEVEL INVERTERS are introduced in 1975.for above intermediate voltage applications. The name MULTI LEVEL began with the three-level converter.By enormous advancement in power semiconductor switches, in electric drives increasing the phase number greater than the conventional three phase especially in locomotives, naval, aerospace, and electrical vehicles industry has many advantages than three phase. In this view, here five phase VSI has developed. This paper aims at comparing the performance of conventional two level inverter Diode clamped and Capacitor clamped topologies of 5-phase multilevel inverter (3-level) using sinusoidal pulse width modulation. SPWM is highly economical, has more efficiency, controllability. These circuits are analyzed by using simulation software package such as MATLAB.

The major analysis has been based on the induction machine drive system that is for the analysis of the carrier based PWM two level source inverter. The unbalanced conditions are mainly to handle the results of simulation for the analysis that results in the two fault conditions. The system setup has been involving the voltage source inverter as well as the five phase multi-level inverter. The effects are through performing the scenarios which consider the performance effects with the load on induction machine. The simulation is based on the imbalance conditions which results on the oscillations depending on the electromagnetic torque through the attendant reduction of the torque rating. The larger slipping has been in the rotor speed.
