Vectorial PWM methods, implementation and results for some AC-DC converter structures

A list of vectorial pulse-width modulation (PWM) methods was derived for three-phase AC-DC converters, namely, the full-bridge, the delta inverter, and the incomplete bridge. Significant results of these techniques are reported for each converter, consisting of commutation rates, maximum attainable amplitudes, and harmonic spectra. A digital implementation scheme is also presented.<>
