Efficiency is a critical indicator for evaluating motor performance. This article utilizes id as the control variable and aims to minimize the total loss of interior permanent magnet synchronous motor (IPMSM) as the optimization objective, thereby developing an IPMSM efficiency optimization control method based on particle swarm optimization. The proposed method eliminates the need to solve complex high-order analytical equations associated with loss minimization control and facilitates the simultaneous optimization of copper loss and iron loss. Experimental results show that, compared to the id = 0 control and maximum torque per ampere control, the proposed approach enhances efficiency by 1.82% and 1.18%, respectively.

This article investigates a bidirectional dc–dc converter having a very high voltage gain for grid integration of a microgrid supported by renewable power sources. The proposed converter interfaces the low-voltage solar PV and battery energy storage systems with a high-voltage system. Because of its large voltage gain both in forward and reverse operating modes, the proposed converter can be used at lower and moderate duty ratios. In comparison to previously reported topologies of a similar nature, this converter can provide better performance with fewer switches and passive components, resulting in better efficiency. The input current's ripple is observed to be lowered as a result of the parallel operation of inductors. The converter stability is investigated using state space modeling and small signal analysis. The laboratory hardware prototype confirms the suggested converter's effectiveness for bidirectional operation, and the outcomes are in line with theoretical studies.

Aiming at the problem of generating inrush current at the startup instant of three-phase voltage-type pulse width modulation (PWM) rectifiers, the principle of inrush current generation is analyzed, and a method of generating a retarded curve based on tracking differentiator (TD) is studied. The rectifier startup inrush current can be effectively suppressed by dynamically adjusting the slope of the dc bus voltage reference value. In addition, the relationship between the TD parameters and time t is investigated using the Newton iteration method. The proposed method is compared with the segmental given method, and the effectiveness and superiority of the proposed method are verified by simulation and experiment.

Research towards increasing the powertrain system efficiency in battery electric vehicles is crucial for increasing vehicle range or decreasing battery requirements and reducing total cost of ownership. The pulse and glide (PnG) method is a discontinuous torque control strategy that decreases eDrive energy consumption via a software-based approach for rare–Earth–free electric motor powertrain systems. The proposed method increases system efficiency by repeatedly accelerating the vehicle at peak efficiency operating regions of the powertrain and allowing the vehicle to coast rather than applying a constant torque command. In this article, a vehicle model is developed to determine the forces acting on the vehicle to dictate torque requirements of the system and to analyze the acceleration and speed profiles of the proposed PnG torque pulses. A baseline wound field synchronous machine (WFSM) and IGBT based inverter is utilized to evaluate the percentage reduction in system energy consumption due to the PnG control strategy. An optimal approach to select PnG duty cycle and pulse period is proposed to maximize energy savings while maintaining acceptable levels of speed variation in a fixed vehicle speed operating condition. A novel jerk limitation controller methodology is introduced to mitigate user discomfort due to the modulated torque profile. The framework is employed to determine the percentage reduction in energy consumption attainable across the speed range of the powertrain system and to generate look up tables of region based PnG duty cycle and pulse period for control implementation.

The demand for electric vehicles (EVs) is growing fast in the recent years due to the increasing energy crisis and environmental concerns. However, the operation of the EVs is limited due to the reduced drive range and lower torque generation. Dedicated motor drive for each wheel can solve these problems. Thus, a multidrive system for EV operation is becoming an important research area. In addition, integrated converter for motor drive can reduce the size and improve the operation further. These converters require wide voltage gain due to significant variations in the voltage of the EV sources. The resonant converters are well-suited for wide voltage applications with soft-switching capabilities. However, achieving significant voltage gain requires a wide frequency range. Thus, this article presents a multiport reconfigurable resonant converter that integrates LLC and LLC-C resonant networks for narrow frequency operation. Moreover, this article proposes a dynamic programming (DP) algorithm to determine the optimal torque distribution between the split motors. Based on the analysis and simulations the torque allocation ensures that the motor operates within the high-efficiency region for different driving cycles due to the DP algorithm. The results are compared with the 50% torque distribution, which shows that the proposed strategy can improve the driving range over 15% . This article includes experimental verifications of the multimotor drive operation.
