“…It can be seen that negative and positive sequence currents in (12) are converted to DC currents and 2nd order harmonics in (13) in dqz frame respectively. By eliminating the DC values and 2nd order current harmonics in dqz frame, the current unbalance in z 1 z 2 sub-plane can be eliminated.…”

“…Although they are not related to the electromechanical energy conversion [10], it will affect the total harmonic distortion (THD) and efficiency. In order to suppress the 5th and 7th voltage harmonics, several PWM strategies [10] [13][14][15][16] were introduced to synthesize the voltage command in αβ sub-plane and maintain zero voltage in z 1 z 2 sub-plane during each PWM period. However, there are still abundant 5th and 7th current harmonics due to the inverter non-linearity [17].…”

“…Instead of the six-phase VSI, PWM strategies [11,[19][20][21], and complex matrix transformation of VSD control, two individual commercial single three-phase VSI inverters can be employed to drive each set of single three-phase windings in the dual three-phase machine individually. The twoindividual current control is a very practical method in industry applications as it duplicates the vector control for a single three-phase machine.…”

--The relationship between the two-individual current control and the vector space decomposition (VSD) control for a dual three-phase permanent magnet synchronous machine (PMSM) is investigated in this paper. It is found that the VSD control is more flexible on controlling the fundamental current in sub-plane and the fifth, seventh current harmonics in z 1 z 2 sub-plane with different PI gains, while the two-individual current control is comparable to the VSD control in having the same PI gains in the and z 1 z 2 subplanes. It is also found that the two-individual current control may have potential instability issues due to the mutual coupling between the two sets of three-phase windings. If the mutual coupling between the two sets is weak to some extent, then the two-individual current control could have the same dynamic performance as the VSD control without the stability issues. Experiments are conducted on a prototype dual three-phase PMSM to validate the theoretical analysis.Index Terms--double d-q synchronous frame current control, double-star motor, dual three-phase, instability, two-individual current control, VSD control.

A modified space vector pulse width modulation (SVPWM) strategy based on vector space decomposition and its equivalent carrier-based PWM realization are proposed in this paper, which is suitable for six-phase asymmetrical dual stator induction machines (DSIMs). A DSIM is composed of two sets of symmetrical three-phase stator windings spatially shifted by 30 electrical degrees and a squirrel-cage type rotor. The proposed SVPWM technique can reduce torque ripples and suppress the harmonic currents flowing in the stator windings. Above all, the equivalent relationship between the proposed SVPWM technique and the carrier-based PWM technique has been demonstrated, which allows for easy implementation by a digital signal processor (DSP). Simulation and experimental results, carried out separately on a simulation system and a 3.0 kW DSIM prototype test bench, are presented and discussed.
