Abstract :
The authors establish the superiority of programmed PWM (pulsewidth modulation) techniques over the conventional carrier-modulated PWMs and provide a critical evaluation of the programmed PWM schemes applied to single and three-phase inverters, thereby providing the framework and guidelines for the selection of the appropriate technique for each application area. Evaluation criteria include harmonic loss factor and total harmonic distortion factors defined at the input and output of the inverter terminals. A simple low-cost solution for obtaining the required PWM switching points is proposed. Selected results are verified experimentally.<>
