Abstract
This study presents a comparative study of Sinusoidal Pulse Width Modulation (SPWM) techniques in a five level H-bridge/Neutral Point Clamped (H-NPC) inverter. Past research on H-NPC inverter used In-Phase Disposition (IPD) to realize the output voltage of the inverter. This study shows that other SPWM techniques could also be used. Simulation results of Alternative Phase Opposition Disposition (APOD), Phase Disposition (PD) and the modified In-Phase Disposition (IPD) are compared based on their harmonic contents.
