Abstract: A discontinuous space vector pulse width modulation (DSVPWM) is presented for v/f control of the induction motor drive to reduce common mode voltage (CMV). The continuous space vector pulse width modulation (SVPWM) algorithms use two zero state voltage vectors at the beginning and end of the switching pattern. More ever SVPWM generate more CMV at zero voltage vectors where as in active zero state pulse width modulation (AZSPWM) algorithms CMV is minimized because of effective zero state voltage vectors. However SVPWM and AZSPWM algorithms use both zero voltage vectors at a time. The proposed DSVPWM based induction motor drive use only one zero voltage vector at a time reducing switching losses and harmonics in output phase voltages and currents. Experimental studies have been carried out for SVPWM, AZSPWM and DSVPWM based induction motor drive in dspace environment and results are presented.
