Abstract :
This paper presents results of dissemination of specific schemes of synchronized pulsewidth modulation (PWM) for adjustment of four neutral-point-clamped (NPC) inverters of dual three-phase system. Specifically, this drive includes openend windings induction motor with two sets of windings spatially shifted by 30 el. degrees. Schemes and techniques of synchronized PWM allow continuous phase voltage symmetry for any operating conditions. Spectra of the phase voltage of multi-converter drive system with synchronized PWM do not contain even harmonics and sub-harmonics during the whole control diapason.
