The purpose of this paper is to develop a novel axial-modular flux switching permanent magnet (AM-FSPM) machine with a sinusoidal flux-linkage waveform and high output torque. Firstly, the operation principle is introduced by field modulation theory. Based on the magnetic circuit analysis, the even harmonic cancellation effect in the flux linkages of the AM-FSPM machine is investigated. Then, the high output torque capability of the AM-FSPM machine is proved by the power sizing equation. In addition, the harmonics distributions in the AM-FSPM machine are revealed by the air-gap flux density mathematical models of two modular parts. Finally, the electromagnetic characteristics of the AM-FSPM machine are investigated by 3D-FEA.

Two dual 3-phase modular permanent magnet (PM) machines with non-overlapping and overlapping windings are analyzed and compared in this paper. One has 42 slots/32 poles (42S/32P) and the other one possesses 96S/32P combination, while two sets of windings have 0 degree phase shift for both machines. The structure specialties of two machines are described together with some constraints. Since two sets of windings are fed by independent inverters, operations with both sets of windings and only one set of winding are analyzed and compared, especially in terms of torque performance. It is found that the 42S/32P modular machine shows better torque performance than the 96S/32P machine in both operation conditions. The differences in both average torque and peak-to-peak torque ripple become larger with the increase of current, which is mainly due to the difference in saturation levels of two machines under high electric loading condition.

The fast-growing charging load of electric vehicles (EVs) has created significant impact on the secure and economic operation of electric power grid. To effectively quantify future operational risks and optimize control actions of the grid, this paper presents a novel method of short-term forecasting of EV charging load using artificial intelligence algorithms. First, a Prophet model is trained to select key features affecting EV forecasting performance; then, a Bidirectional Long Short-Term Memory (BiLSTM) model is trained to provide high-accuracy forecasting model of EV charging load. The proposed method is tested on actual charging load data obtained from a large EV station in Southern China, and compared with state-of-the-art machine learning algorithms including the traditional Prophet, LSTM, ANN, CNN-LSTM, transformer and N-BEATS. The proposed method of Prophet-BiLSTM model demonstrates higher prediction accuracy.

This paper investigates the effect of the vibration exposure cycles on the lifetime during the thermal qualification tests of winding insulation. The study aims at evaluating the lifetime reduction and the consequent impact on the wire thermal class caused by mechanical stresses. Two groups of samples, i.e., motorettes, resembling the insulation system arrangement of an electrical machine for aerospace actuator application are built and tested. The first group is purely thermally aged, while the mechanical stress is also considered through extra vibrations cycles when the second group is aged (i.e., samples thermally aged and mechanically stressed). The recorded lifetime data are processed via the Weibull approach and the lifetime is determined for both sample groups. In addition, the dissipation factor is measured as a diagnostic marker after each aging cycle, and the results further demonstrate the dominant effect of thermal stress on the insulation lifetime.

The high-frequency common-mode voltage (CMV) generated by switching actions of semiconductor devices may cause premature failure of insulation system and metallic bearings in the motor drive systems. To suppress the common-mode voltage, a filter utilizing motor windings and passive components is proposed in this paper. The simulation of the motor with the proposed integrated filter employing field-oriented control is presented and the results indicate that this filter significantly reduces the peak-to-peak value, RMS value and the high order harmonic components of CMV. Moreover, the negative effects associated with this integrated filter in the motor, including energy losses caused by passive elements and increased output torque ripple of the system has been investigated in the paper.

An improved high-frequency pulsed sinusoidal voltage signal injection (HFPS-VSI) sensorless vector control strategy applied to interior permanent magnet synchronous motor (IPMSM) is proposed in this paper. The Luenberger observer is utilized to extract the fundamental current without any low pass filter (LPF). Hence, it can enhance the system bandwidth. Moreover, the novel primary current extraction method has no magnitude error and phase delay, presenting strong parameter robustness at the fundamental frequency. In the feedback gain matrix design, the left-shifting design method of the observer pole is adopted in this paper, which makes the Luenberger observer keep a strong anti-interference in the full-speed region. The effectiveness of the novel HFPS-VSI algorithm is verified on a two-level IPMSM platform by simulation and experimental tests compared to the conventional HFPS-VSI sensorless control strategy. These results reveal that the novel HFPS-VSI algorithm has a better steady-state and dynamic performance than the traditional HFPS-VSI method.

With the increasing demand for speed and power of finite volume high-speed permanent magnet motor system, the design of motor is generally faced with the challenges of high harmonic content of air gap magnetic field and current, changing load conditions and high working temperature. In this paper, combined with the operating conditions of high-speed permanent magnet motor, it is of great significance to study stator iron consumption. Taking the ultra-high-speed permanent magnet (UHS-PM) motor for a 22kW/90000rpm hydrogen fuel cell air compressor as an example, the electromagnetic scheme is designed, and a two-dimensional finite-element analysis model is established. By dividing the stator core area of the motor. The variation law of magnetic density is analyzed, and the effects of current harmonics and rotational magnetization are studied. A UHS-PM motor for hydrogen fuel cell air compressor is developed and verified by experiments. The simulation analysis shows that the current time harmonic has a great influence on iron core eddy current loss and small effect on the iron core hysteresis loss, in a certain range, with the increase of carrier and modulation ratio, the current distortion rate decreases with the reduction of iron loss. Compared with the sine wave power supply, the simulated loss of the inverter power supply simulation is closer to the experimental data of the prototype, which further verifies the accuracy of the simulation analysis method.

Dual active bridge (DAB) dc-dc converter has been obviously attracting more research interests in recent years. Considering the reliability of DAB is very significant, in this paper, we propose a fault diagnosis and location method for insulated gate bipolar transistor (IGBT) open-circuit fault. By analysing the operating modes and waveforms of DAB converter when IGBT occurs open-circuit fault, the inductance current and midpoint voltage of bridge arm are selected as the fault features to detect the faulty IGBT. The proposed method needs only one current sensor and two voltage sensors to reduce hardware costs compared with the existing method. The whole diagnosis process is also given in detail. Finally, the DAB converter model with the proposed fault diagnosis and location method is simulated in PLECS to verify its accuracy.

In the dual-bridge series resonant converter (DBSRC) working at a high switching frequency, the dead-time effect becomes a serious issue. When the minimum current trajectory (MCT) method is applied, the inductor current cannot be minimized due to the dead-time effect, and the range of the soft switching is reduced. Considering the dead-time, this paper firstly performs a theoretical analysis of the transmission power and soft-switching characteristics based on the fundamental harmonic approximation (FHA) approach. Then, a minimum current trajectory method considering dead-time (MCT-d) is proposed to achieve minimum inductor current by compensating the dead-time. Meanwhile, the method can extend the soft-switching range as well. Finally, the experimental results validate the theoretical analysis and the improvement of the converter efficiency.

In this paper, to provide a convenient and low-cost charging solution for dual-motor EVs, a dual-motor traction system is employed to build an integrated on-board battery charger. In the proposed system, a five-phase flux-switching permanent-magnet (FSPM) motor and a three-phase FSPM motor are employed as the front and rear driving motor respectively in the driving mode. While in the charging mode, the five-phase FSPM motor and its inverter are applied to construct a boost-based ac/dc converter, which converts the grid power into dc, as well as the three-phase FSPM motor and its inverter are used as a buck converter to adjust the dc voltage to satisfy the battery charging requirement. The effectiveness of the proposed integrated charger is verified by simulation.
