Abstract
In order to provide a reduction of harmonic current for Dual Three-Phase Permanent Magnet Synchronous Motor (DTP-PMSM), this paper proposes a Space Vector Pulse Width Modulation (SVPWM) technique based on vector space decomposition method (VSD). By this technique, the analysis and control of the machine are accomplished in three two-dimensional orthogonal subspaces. Among the 12 voltage vectors having maximum magnitude, the Successive Four-Vectors method (S4V) is chosen instead of the Adjacent Two-Vectors method (A2V). Thereby, the principle of reference voltage vector selection and the method of time calculation are discussed. The validity and the efficiency of the selected method are confirmed by simulation results.
