Abstract :
In this paper different open loop PWM control techniques for multilevel voltage source inverters are investigated and compared. For sinusoidal PWM control, a comparison between different carrier techniques with different modulating signals is performed. This comparison includes total harmonic distortion and distortion factor of the phase and line voltages. A comparison between different modulating signals in sinusoidal PWM (pure sinusoidal, third harmonic injection, and dead band), space vector modulation, and sigma-delta modulation is performed. This comparison includes total harmonic distortion, distortion factor, fundamental, and harmonic RMS of the line voltage.
