In order to avoid asynchronism of standard schemes of space-vector modulation, new method of synchronized pulsewidth modulation (PWM) has been applied for scalar control of symmetrical six-phase (dual three-phase) induction motor drives fed by two three-phase inverters. Basic schemes of synchronized continuous and discontinuous PWM, and also its combinations, disseminated for control of symmetrical dual three-phase systems, have been analyzed. Simulations give the behavior of symmetrical dual three-phase system with low switching frequency, controlled by algorithms of synchronized PWM. The spectra of the phase voltage of sixphase drives with synchronized pulsewidth modulation do not contain even harmonics and sub-harmonics during the whole control range, which is especially important for the high power/high current applications.
