Assessment of torque pulsation in inverterd fed three-phase induction motor drive for 180° and 150° conduction modes

This paper presents qualitative and quantitative approach to access torque pulsation in an open-loop inverter fed induction motor drive system. The inverter used to supply a three-phase induction motor operates in either 180deg or in 150deg conduction mode. A comparison in the performance of the drive system is presented for the two conduction modes. Analytical and simulation results are provided to support the findings.
