摘      要：Dual three-phase permanent-magnet synchronous machines(DTP-PMSM)connected with a single neutral point provide a loop for zero-sequence current(ZSC).This paper proposes a novel space vector pulse width modulation(SVPWM)strategy to suppress the *** vectors are selected as basic voltage vectors in one switching *** fundamental and harmonic planes and the zero-sequence plane are taken into consideration to synthesis the reference voltage *** suppress the ZSC,a non-zero zero-sequence voltage(ZSV)is generated to compensate the third harmonic *** than triangular carrier modulation,the sawtooth carrier modulation strategy is used to generate asymmetric PWM *** modulation range is investigated to explore the variation of modulation range caused by considering the zero-sequence *** the proposed method,the ZSC can be considerably *** simulated and experimental results are presented to validate the effectiveness of the proposed modulation strategy.
