Abstract:

Analysis of different modulation techniques for reverse voltage nine level inverter is discussed in this paper. Reverse voltage topology requires fewer components compared to existing inverter Topologies and requires fewer carrier signals and gate drives. Therefore, the overall cost and complexity are greatly reduced particularly for higher output voltage levels. Multi carrier Sine Pulse Width Modulation (SPWM) techniques are widely used for different multilevel inverter topologies. The chosen multilevel inverter is simulated for various multicarrier based Pulse Width Modulation (PWM) techniques and selective harmonic elimination method. The multicarrier SPWM techniques include In Phase Disposition (PD) PWM, Alternative Phase Opposition and Disposition (APOD) PWM and Variable Frequency (VF) PWM. It is observed that sinusoidal reference with Alternative Opposition and Disposition (APOD) provides output with relatively low distortion.
