Comparison of space vector modulation techniques based on performance indexes and hardware implementation

Space vector modulation (SVM) techniques are becoming an industry standard, especially when it comes to fully digital AC motor drives. In this paper, four different SVM techniques are evaluated based on defined performance indexes. A new performance index is defined for comparison based on switching loss; comparison based the on method of hardware implementation is also discussed. Simulation results indicate that the choice of the SVM technique to be used will depend on the optimized criteria under consideration, whether it is the torque/current ripple, the harmonic loss or the switching loss.
