“…The inductance values may be extracted from numerical derivations [7], FE simulations [8] or experimental tests [9]. Circuit-oriented method is an alternative way to investigate the induction machine [10] which can model the faults in both stator and rotor sides, such as inter-turn short circuit or broken rotor bar.

Abstract-A general modelling technique is proposed for a triple redundant 3x3-phase permanent magnet assisted synchronous reluctance machine (PMA SynRM). The magneto-motive force (MMF) of the machine is divided into three parts each associated with one 3-phase set. The MMF of each 3-phase set can be described by four variables: d-and q-axis components of the currents, the rotor angle and an MMF offset component which captures the mutual coupling between three 3-phase sets. Therefore the complete machine behavior in all operating conditions can be captured by means of 4-dimensional (4D) tables, which store the flux linkage and torque information. The 4D tables are produced by finite element (FE) analysis for one 3-phase set. As a result, the machine behavior can be predicted by interpolating the 4D tables. The model is capable of representing healthy and fault operations, including unequal current operation in three 3-phase sets, and offers great flexibility for performance assessment, post fault control and fault detection. Its effectiveness is verified by extensive FE simulation and experimental tests in different operation modes. Index Terms-Fault tolerant, fault modelling, permanent magnet assisted synchronous reluctance machine, multi-phase machine, magneto-motive force, MMF reconstruction.

“…In addition, in a conventional or symmetric six-phase machine, the three-phase winding groups are displaced by 60 • . Previous papers [16,17] investigate the SVPWM under the phase failure of this machine, and the basic characteristics are similar to those in a previous paper [14]. For the open-circuit fault of multiphase machines, current follow PWM methods are proposed in previous papers [18][19][20] to maintain the circular trajectory of the stator flux.…”

Six-Phase Space Vector PWM under Stator One-Phase Open-Circuit Fault Condition

et al. 2018

The torque pulsation and speed pulsation of a six-phase induction machine with double Y-connected windings displaced by 30 • increase after one phase of the stator winding is open-circuited. To reduce the pulsations, a method of six-phase space vector pulse width modulation (PWM) with fault-tolerance is proposed. The star point of the open-circuit winding group is connected to the centre point of the converter DC voltage. The 32 column matrices, which represent 32 stator winding voltages, are mapped to the d-q and z 1-z 2 planes using a new five-dimensional orthogonal matrix; then, 32 basic vectors are obtained. By using an optimal model, six auxiliary vectors and an equivalent null vector are constructed, the magnitudes of which are all zero in the z 1-z 2 plane. By using the auxiliary vectors and equivalent null vector, the reference vector is synthesized, the zero magnitude of which in the z 1-z 2 plane can suppress the harmonic voltages, and the circular trajectory of which in the d-q plane can make the torque smooth. The simulation and experimental results show that the torque pulsation range and speed pulsation range of the proposed method with fault-tolerance are 30% and 25% of those of the classical method without fault-tolerance, respectively. Thus, the phase-deficient operation performance of the system is improved.

“…The specific attraction of six-phase machines versus other possible alternatives typically returns to their ready adaptation with standard three-phase converter topologies. Through an enriched body of literature, six-phase machines have been studied with different aspects pertinent to their modeling, control, and applications [14]- [19]. With the dual three-phase inverter is the off-the-shelf drive topology for six-phase machines, dual three-phase MMC has been applied to drive both asymmetrical and symmetrical MV six-phase machines in [20] and [21], respectively.…”

The nine-arm modular multilevel converter (9A-MMC) has been recently proposed as a reduced MMC topology variation for six-phase drive applications, with 25% reduction in the number of employed arms and associated components, compared to a standard dual three-phase MMC, however with a limited output voltage amplitude. This paper proposes a hybrid 9A-MMC comprised of half-bridge submodules (SMs) in both the upper and lower arms, and full-bridge SMs in the middle arms. By employing the negative-voltage state of the fullbridge SMs, the hybrid 9A-MMC avoids the limitations imposed on the dc-link voltage utilization, while achieving further reduction in the component count, compared to a standard 9A-MMC with identical half-bridge SMs. The operating principles of the proposed hybrid 9A-MMC are illustrated with mathematical analysis, while its characteristics are verified through both simulation and experimentation. An assessment of the proposed topology quantifying its employed components is also provided, in comparison to other MMC-based six-phase machine drives.
