With the increase of permanent magnet motor speed, frequencies of low-frequency and high-amplitude electromagnetic force are closer to the low-order motor modes, resulting in more serious vibration and noise, which further restricts the increase of permanent magnet synchronous motor speed. In this paper, vibration and noise optimization of a high-speed permanent magnet motor for air compressors is analyzed from the point of structural modes. Stiffness of the motor body is improved by using stiffeners to change natural frequencies of main vibration modes. So that natural frequencies of main modes are far away from electromagnetic force frequencies, and the vibration and noise of the high-speed permanent magnet motor is reduced. Results show that natural frequencies of the main vibration modes can be changed effectively by adding annular stiffeners, and the best vibration and noise reduction effect can be obtained by optimizing radial thickness of the stiffeners.

Dual active bridge (DAB) and multiple active bridge (MAB) converters tracks attention of industrial and transportation applications such as aircrafts, high-speed trains and electric vehicles. The key energy interface components in DAB and MAB is the high-freuqency 2-winding or multi-winding transformers. This paper proposes multi-winding transformer equivalent circuit models used for DAB and MAB converters, including T-$pi$-shaped model and $pi$-shaped model. T-$pi$-shaped model may be used to analyze copper loss, iron loss and iron core saturation. $pi$-shaped model could be used to achieve average power transfer equations accurately together with ZVS discussions. These models was derived by math calculation and verification by simulations and experiments with different modulation conditions.

The deadbeat predictive controller theoretically features a two-sample step response with the existence of one-sampling-period digital delay. Nevertheless, high sensitivity to high frequency perturbation is an important practical issue that restricts its application in reality. This paper proposes a novel deadbeat predictive flux linkage control method with disturbance suppression scheme for permanent magnet synchronous motor drives. The flux linkage prediction and voltage command calculation blocks are revised with additional state feedback and parallel integral path. Simulation results show that the proposed control scheme show immunity to different types of disturbance. Meanwhile, the steady-state error is eliminated even with mismatch of flux linkage parameter.

Coordinated charging activities of electric vehicles (EVs) in charging stations with distributed photovoltaic (PV) resources plays an important role in promoting PV consumption, saving electricity costs and improving profits for charging stations. However, the uncertainties caused by PV power output and EV arrivals impose grand challenges to achieve the desired optimal control performance. This paper presents a novel real-time EV-PV coordination strategy using distributed reinforcement learning (RL) agents, for providing real-time controls based on high-precision short-term prediction of PV outputs and EV arrivals, which can effectively avoid large deviations between actual and optimal conditions. The proposed RL-based control strategy can balance short-term and long-term benefits and achieve global optimization for charging stations. The feasibility and effectiveness of the proposed algorithm are verified by comprehensive case studies with realistic EV charging station data.

The fault diagnosis function of the battery management system (BMS) is crucial for battery pack safety and reliable operation. This paper proposes a new series-parallel connected battery pack voltage measurement design scheme, which can save voltage sensors number from n to 0.75n for n cells in series. The multi-fault diagnosis strategy is proposed by analyzing the law of battery pack current and voltage signals. Three kinds of fault, including connection fault, sensor fault, and micro external short circuits (mESC) fault, were simulated to verify the effectiveness of the diagnosis strategy. This paper provides an important reference for the research on fault diagnosis of series-parallel battery packs by applying measurement information in practice.

For wireless power transfer (WPT) system, reliable data exchange between the transmitting side and the receiving side is generally required to improve the overall performance of the system. In this paper, a dual-resonant full-duplex communication method with resistance-based duplexer is presented. The two resonant frequencies of the reconfigurable double-sided LCC topology are, respectively, selected to exchange data in the forward and the backward data channel. The performance of the data transfer channel operated under the two frequencies, including the data receiving voltage and the response time of loops, are investigated, and the design considerations and principles to ensure similar transfer characteristics for different carrier frequencies are provided. The performance of the resistance-based duplexer is explored, and the corresponding parameter design is given. Furthermore, the interference between the power and data transfer channel is analyzed and the methodology to suppress the crosstalk is also provided. With the well-designed parameters, 1 kW power with a rate of 83.3 kbps full-duplex communication is obtained and the effectiveness of the proposed method is validated.

Vernier machines (VM) are widely used in direct drive field for its simple structure and high torque density at low operation speed. In order to increase torque quality furtherly and reduce the cogging torque and torque ripple, pole-shaping has been an alternative approach applied in VM. However, pole shaping brings manufacturing difficulty, which limits the development of pole-shaping in machine design. A new VM with compensatory PM array (CPMVM) is proposed, which can provide high quality torque production. The compensatory PM array consists of several PMs with different thickness, which is used to optimize the airgap flux density for high quality torque. Compared to the conventional pole-shaping, the proposed machine can achieve high sinusoidal airgap flux density distribution without increasing equivalent airgap length in magnetic circuit. The proposed CPMVM and the conventional VM are designed sharing the identical key design parameters and optimized by multi-objective evolutionary algorithm. The back electromagnetic force and torque production of the designed machines are analyzed using finite element analysis (FEA). The FEA-predicted results indicate that the proposed CPMVMs exhibit good inhibitory capacity for torque ripple and have high PM utilization.

This paper proposes a dynamic fault-tolerant control strategy of DC-side for three-phase to single-phase cascaded converter. The three-phase to single-phase cascaded converter is the key equipment in advanced traction power supply system and the fault-tolerant control strategy can enhance the reliability of this system. First, through the in-depth analysis of the three-phase to single-phase cascaded converter, when the cascaded converter fails at the module level, the fault module is located by fault detection and bypassed. And then the dynamic fault-tolerant control strategy is put into operation to achieve continuous and stable operation of the system, which improves the overall reliability of the system. Finally, simulation results are given to verify the feasibility of the proposed dynamic fault-tolerant control strategy.

This paper introduces an innovative concept for implementing constant current (CC) and constant voltage (CV) battery charging using the proposed three-coil-based single stage inductive power transfer (IPT) converter with voltage-sigma architecture. In proposed converter, an adjustable dc voltage and a constant dc voltage are provided by two receiver coils, i.e., the intermediate receiver coil (IRC) and the back-end receiver coil (BRC). Such two dc voltages are stacked together on the battery port. The total output voltage is controlled by the adjustable dc voltage using semi-active rectifier (SAR) in IRC. Therefore, BRC can always operate the optimized operation point to ensure high efficiency. Since the adjustable dc voltage is much lower than the constant dc voltage, low power-rating switches can be used in SAR, which is benefit for reduction of switching loss. Primary inverter can achieve zero phase angle (ZPA) operation, fixed switching frequency and zero voltage switching (ZVS) without wireless communication links. Finally, a simulation of 3kW IPT system is built to verify the feasibility of proposed method.

In this paper, an integral-type position and speed estimator is developed for sensorless control of PMSM to enhance the filter ability in estimating the rotor speed. Based on the variable gradient method, a Lyapunov function is developed to show that the proposed integral-type estimator is stability. Compared with the SRF-PLL based estimator, the proposed integral-type estimator has better filter capability in estimating the rotor speed. Simulation tests also verify the superior performance of the proposed integral-type estimator, in terms of accurate speed estimation.
