N2 - Dual three-phase permanent magnetic synchronous machine with single neutral point (SDTP-PMSM) has excellent performance in fault tolerance state, however, the unexpected 3rd-order harmonic components are introduced to phase current during healthy state. In this paper, two 5-vector space vector pulse width modulation (SVPWM) strategies are investigated to suppress 3rd-order harmonic currents in such machines. Considering the synthesized reference voltage, the proposed strategies achieve performance comparable to the previous 5-vector strategy while minimizing computation time. in case of the pre-synthesizing vectors. Furthermore, the 12-sector strategy offers a denser vector selection compared to the 6-sector strategy, resulting in a greater reduction of harmonic components in the current. Whilst the same time, the boundaries of the two strategies are analyzed, and discuss the possibility of vector synthesis for extending the modulation boundary is discussed. Finally, the simulation results verify the effectiveness of the two strategies.
