Power quality improvement at both grid and motor ends is always an industrial concern for multilevel inverter (MLI) fed induction motor drives. The power quality of an induction motor drive (IMD) is vehemently influenced by the pulse width modulation (PWM) technique of the drive systems. The conventional triangle carrier based level shifted (LS) space vector PWM (LS-CSVPWM) technique provides less power quality problems than the LS sinusoidal PWM (LS-SPWM). In this paper, an advanced LS carrier based bus-clamping PWM (ALS-BCPWM) technique is proposed to mitigate the power quality problems of t...
The improvement of power quality at the supply side and the motor side for induction motor drives (IMDs) is always an industrial key interest. The traditional pulse width modulation (PWM) technique used in switching and controlling the IMDs greatly influences the grid power quality. In this paper, a new modified level shifted carrier based PWM technique is proposed for a multilevel inverter (MLI) based IMDs. A 36-pulse diode bridge rectifier is used at the input side of the inverter to suppress the total harmonic distortion (THD) of the supply current. The proposed PWM technique utilizes third...
Solar photovoltaic (PV) powered water-pumping systems are proving to be a very effective in areas where the electric grid is not available. The pulse width modulation (PWM) technique, the power quality, and the torque ripple of an induction machine employed in the solar PV fed water-pumping applications have always been a concern. This paper proposes a modified reference based PWM scheme for a neutral point clamped (NPC) inverter based induction motor drive (IMD) for the solar PV fed water-pumping system. This work mainly focuses on the improvement of power quality of induction motor, converte...
