Abstract :
This paper presents results of application of novel methodology of direct synchronized pulsewidth modulation to a dual inverter-fed open-end winding induction motor drive with elimination of zero sequence currents. Control algorithms are based in this case on the 120°-shifting of control and output signals of two standard three-phase inverters. Spectra of the phase voltage of drive systems with algorithms of synchronized PWM do not contain even harmonics and sub-harmonics (combined harmonics), which is especially important for the systems with increased power rating. Simulations give the behaviour of different versions of synchronized PWM in these systems.
