Abstract
Many industrial applications require variable speed drives. In recent days many researchers have focused on Pulse Width Modulation (PWM) based multilevel inverter drives for inverter quality improvement. Inverter performances are evaluated by calculating overall THD of output signals. In this paper a new multilevel inverter topology is described with reduced number of switches. Different Sinusoidal PWM schemes (PD, POD, APOD) has been employed to the reduced switch inverter and a comparative performance is analyzed of the inverter in terms of Total Harmonic Distortion. The reduced switch multilevel inverter has been designed and different SPWM schemes have been developed in MATLAB SIMULINK environment.
