Abstract: The two level conventional converters are slowly substituted by multilevel converters because of mitigated THD and stress reduction on power semiconductor switch. The rigorous survey performed on various industrial applications using variable speed drive with 2-level and N-level inverter lies in selecting the topology and control methods. For different applications, one control method may be suitable to avail good characteristics. In this paper, the techniques SPWM and SVPWM applied on 9-level diode clamped N-level inverter operated induction machine are compared for various industrial applications. The analysis concludes: For speed control and at high and normal MI, SPWM is preferable and at low and normal mi values, SVPWM is preferred in constant V/f method of induction machine.
