“…In [73], ZCMV is achieved in an asymmetrical six-phase motor with interleaved windings by PWM signal shifting arrangement. Also, Carrier phase shifting [74], [75] and model predictive PWM [76] are applied on dual three-phase motors to improve the performance. Although the use of complex topologies can, at least in principle, eliminate common-mode voltages, ZCMPWM will increase output ripple and harmonics, increase switching losses, and reduce bus voltage utilization.…”

The impact of electromagnetic interference (EMI) is an increasingly important aspect of the performance of switching inverters. The challenges of managing EMI continue to grow with the emergence of wide bandgap (WBG) devices, the trend towards ever-greater integration and higher power rating. This paper reviews suppression methods for the conductive common-mode (CM) EMI in inverter fed motor drives. In order to span EMI suppression across the full system design process, the review considers both mitigation from the sources and suppression along the conduction paths. Furthermore, the shortcomings and merits of the reviewed publications are discussed, and their attenuation frequency range and attenuation level are compared. It is demonstrated that the CM EMI at low frequency is mainly determined by the PWM strategies and can be reduced or even theoretically eliminated through zero common-mode control. On the other hand, the CM EMI at high frequency is markedly influenced by the switching transients of the power devices. Thus, various drive circuits are reviewed which improve the switching behavior. Finally, the deployment of passive and active filters to suppress or compensate for the EMI is discussed.INDEX TERMS Conductive EMI, EMI sources, inverter fed motor drives, propagation paths.

“…According to the characteristics of N*3-phase PMSM, the mathematical model and characteristic of each motor units is identical with a regular PMSM, and all the characteristics of each motor units are repetitive. In addition, the voltage-seconds characteristic of any two VSIs should be the same [14][15][16]. The control of a VSI can be analogous to that of a conventional inverter [12,34].…”

“…Compared with the conventional multi-phase PMSM, the control algorithm is easy to implement, which is similar to the traditional three-phase PMSM control algorithm. In [14,15], a two-segment three-phase PMSM system powered by two inverters with phase-shift PWM has been developed, which can fulfill the requirement of high power and mitigation of torque ripple. In [16,17], a dual three level T-type neutralpoint clamped inverter fed dual PMSM topology was proposed for the high power automotive applications, which can reduce current stress and capacitors' voltage deviation.…”

The permanent magnet synchronous motor (PMSM) has become a core component of electromechanical energy conversion in the modern industrial field. In order to expand the application of the PMSM in the field of high power traction, a robust predictive torque control (R-PTC) strategy for the Nsegment three-phase PMSM (N*3-phase PMSM) is proposed in this paper. Firstly, the output characteristics of the N*3-phase PMSM are illustrated with the finite element analysis method, and the mathematical model is established. Then, the six-segment three-phase PMSM predictive control system driven by six parallel inverters is designed to generate the required torque. Further, the influence of the parameter mismatch on the predicted torque and stator flux is taken into consideration based on the conventional predictive torque control (PTC). Finally, a novel R-PTC method with the proportional controller is developed for the N*3-phase PMSM, which can effectively improve accuracy and robustness of predictive control performance under parameters mismatch. Simulation and experimental results verify that, compared with the conventional PTC, the proposed R-PTC method can make the predicted stator flux and torque value accurately track its reference values while achieving lower stator flux and torque ripple.

“…ULTI-PHASE permanent magnet synchronous motor (Multiphase PMSM) has been widely adopted in many special applications ranging from high power traction vehicles to marine propulsion due to its outstanding advantages of the better fault-tolerant capability, high power and torque densities [1][2][3]. In order to optimize the performance of multi-phase PMSM, a novel multi three-phase PMSM (N*3-phase PMSM) with special mechanical degree winding placement is investigated in [4][5][6]. The main benefit of this N*3-phase PMSM has extremely lower cogging and higher torque quality compared with conventional multi-phase PMSM.…”

In this study, a novel predictive torque and stator flux control (PTSF) method is proposed for Nsegment three-phase PMSM (N*3-phase PMSM), which can effectively eliminate the influence of parameter mismatch on stator flux and torque. The proposed PTSF method has two loops, stator flux loop and torque loop, both implemented with robust predictive control algorithm. First, the stator flux predictive controller with parameter robustness is designed, and the sensitivity of its parameters is analyzed. In the dq stator flux space, the robust stator flux predictive control with one-step delay compensation is then proposed, which can effectively enhance robustness against parameters mismatch. Moreover, the robust torque predictive control based on unknown torque disturbance observer is developed, which can effectively strengthen the robustness against the load torque disturbance and parameter mismatch. Finally, the validity and feasibility of proposed PTSF method are verified by simulation and experiment. Excellent simulation and experimental results were achieved with respect to the stator flux tracking error, torque /flux ripple reduction, and stator current distortion over conventional predictive torque control (PTC).
