Optimum design of an induction motor for operation with current source inverters

The aspects of design associated with the current source inverter (CSI) induction motor drive are reviewed and a systematic procedure for the optimum design of the drive is presented. The optimisation is carried out using the sequential unconstrained minimisation technique. The study takes into account the inherent slow commutation process, the torque pulsation and the peak voltage stress in the CSI drive. A comparative study of the optimum CSI fed motor and a cost optimal mains fed motor under CSI supplies is made using digital computer simulation. The studies show that the method presented can form the basis for standardised CSI fed drive design of different ratings, in the large-volume production of these drives.
