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...
Novel methodology of synchronized pulsewidth modulation (PWM) has been disseminated for control of symmetrical six-phase (dual three-phase) induction motor drives fed by two three-phase inverters with single DC voltage source. Control algorithms are based in this case on the 60deg-phase- shifting of control signals of two standard voltage source inverters. Four basic schemes of synchronized continuous...
