Multi-Vector SVM: A New Approach to Space Vector Modulation Control for Six-Phase Induction Machines
Résumé
In this paper a new space vector PWM configuration for control of dual-three phase induction machines (DTPIM) is described. The machine has two three phase stator windings spatially shifted by 60 electrical degrees and connected to single neutral. This model improves the system reliability when more than one phase will be opened. The dynamic model of the machine is based on the three two dimensional orthogonal subspaces. The proposed multi-vector space vector PWM is more effective in reducing harmonic currents, and comparing to traditional space vector decomposition method is simpler and reduces consuming time. The simulation results illustrate the validity and efficiency of the proposed method.
