Interior permanent magnet synchronous motors (IPMSMs) are used for various applications and high efficiency control is required. Maximum torque per ampere (MTPA) control is a method to control IPMSMs with high efficiency. However, since the motor parameters vary with magnetic saturation, MTPA control cannot be easily realized. Here in, we propose a fully online and automatic MTPA control method. To find the MTPA point while driving the motor, it is necessary to predict the entire flux linkage surface. Therefore, the flux linkage surface is approximated by a plane from the sensor information at a specific current condition that considers the effect of magnetic cross-saturation. MTPA control is achieved using the estimated flux linkage plane and the gradient ascent method. The simulation results reveal that the torque maximized in two search periods, which was completed in 0.06 s. The proposed method is effective for a wide current range.

Lately, permanent magnet synchronous motors (PMSMs) have been widely employed in several fields such as industrial equipment, home appliances, and electric vehicles due to their high efficiency and power density. Previous studies have confirmed that PMSM motor drive system with deadbeat control has a superior response to the current reference. In this paper, a universal smart power module (USPM) controller is used to realize a high-performance motor drive system. Because this controller can achieve 50 MHz sampling of the state variables, we proposed a 10 MHz multi-sampling deadbeat control that uses fast sampling ability to follow the load disturbance fluctuation even between carriers and to enhance the robustness to parameter variations. The proposed method was verified through simulations and experiments.

For the online condition monitoring of IGBTs, a new estimation method of both the junction temperature (TJ) and the load current (IL) of IGBTs using a momentary high-Z gate driving (MHZGD) from the output voltage (VOUT) of the gate driver is proposed, which can be integrated into the gate driver ICs. TJ is estimated from VOUT difference during and after the MHZGD period, and IL is estimated from VOUT during MHZGD. In the 110 switching measurements at 11 different TJ's from 25 °C to 125 °C and 10 different IL's from 12.5 A to 80 A for each of the three IGBTs, TJ and IL estimation errors in a low test cost parameter determination method are + 4.9 °C / − 8.4 °C and + 1.1 A / − 4.3 A, respectively. In contrast, TJ and IL estimation errors in a parameter determination method with small error are + 4.9 °C / − 8.1 °C and + 1.0 A / − 1.8 A, respectively.
针对igbt的在线状态监测，提出了一种利用瞬时高z栅极驱动(MHZGD)从栅极驱动器输出电压(VOUT)估计igbt结温(TJ)和负载电流(IL)的新方法，该方法可集成到栅极驱动集成电路中。TJ由MHZGD期间和之后的VOUT差估计，IL由MHZGD期间的VOUT估计。三种igbt分别在25°C至125°C的11种不同TJ和12.5 A至80 A的10种不同IL下进行了110次开关测量，在低测试成本参数确定方法中，TJ和IL估计误差分别为+ 4.9°C /−8.4°C和+ 1.1 A /−4.3 A。相比之下，小误差参数确定方法的TJ和IL估计误差分别为+ 4.9°C /−8.1°C和+ 1.0 a /−1.8 a。

In this paper, we propose asymmetric winding structure to achieve a low torque ripple and high slot fill factor. Existing methods developed for this purpose improve the winding factors of harmonics and the slot fill factor by ensuring that the winding arrangement and number of turns for each coil are asymmetric. In contrast, an asymmetric winding structure generally lowers the symmetry of the magnetomotive force of the stator and generates electromagnetic excitation forces with lower spacial order modes, resulting in increased vibration. Therefore, in this study, we aim to improve the winding factor and the slot fill factor by changing the winding arrangement and the number of turns while considering the symmetry of the electromagnetic field. First, the working principle of techniques for improving the characteristics of the proposed winding structure are discussed. Thereafter, the results of magnetic field analysis and the verification of the said improvements to the asymmetric prototype, along with the effects, are presented.

This paper proposes an innovative integrated inductor technology for hybrid energy source systems (HESS). The proposed inductor utilizes novel variable coupling coefficient integrated inductor (VCCII) technology to integrate two inductors that are required for a dual boost converter for HESS. VCCII has an integrated structure of two inductors, and enables control the coupling coefficient between the two inductors depending on the power distribution ratio of two power sources. In a low-power operation, the coupling coefficient between the two inductors is structurally zero, which enables the VCCII technology to independently control each output of energy sources without interference. In high-power operation, the coupling coefficient of the two windings increases by utilizing the non-linear characteristics of a magnetic core. These coupling effects peak shaving of the inductor current, which contributes to loss reduction and increase the maximum power capability. A prototype result verifies a 50% increase of peak power density and a 15% increase of maximum power capability under 20 V / 100 A and 25 V / 40 A inputs and 42 V output HESS. Additionally, the result gives 1.9 point of efficiency improvement in a double boost converter circuit operating at 100-kHz switching, 810 W output.
提出了一种用于混合能源系统(HESS)的集成电感技术。该电感采用可变耦合系数集成电感(VCCII)技术，将HESS双升压变换器所需的两个电感集成在一起。VCCII采用两个电感的集成结构，可以根据两个电源的功率分配比来控制两个电感之间的耦合系数。在低功耗工作时，两个电感之间的耦合系数在结构上为零，这使得VCCII技术能够独立控制每个能量源的输出而不受干扰。在大功率运行中，利用磁芯的非线性特性，增大了两个绕组的耦合系数。这些耦合效应对电感电流的削峰，有助于降低损耗和提高最大功率能力。样机结果验证了在输入为20 V / 100 A和25 V / 40 A，输出为42 V的HESS下，峰值功率密度提高50%，最大功率能力提高15%。此外，在工作在100 khz开关，810 W输出的双升压转换器电路中，结果给出了1.9个点的效率改进。

A new multiple DC-inputs direct electric-power converter (D-EPC) was proposed. It can be applied to motor-drive systems with two direct-current (DC) power sources. The D-EPC can charge a DC power source with motoring by another DC power source. This charging is controlled by the voltage command multiplied by a power distribution ratio of more than 1.0 for the DC power source supplying power to the motor and another DC power source. If charging power is required in the condition of phase voltage saturation, the phase voltage command calculated using the power distribution ratio of more than 1.0 cannot be increased to more than the phase voltage limit. This paper proposes a new charging control for D-EPCs by controlling the switches on the free-wheel current path. The distribution ratio of this proposed control does not exceed 1.0. The simulation results showed that one DC power source can be charged with motoring by another DC power source using the proposed charging control.

This study investigates an active gate driver (AGD) for an SiC-MOSFET. The source current feedback type AGD utilizes the induced voltage of the source wire inductance as a negative feedback signal to regulate the source current di/dt. Recent improvements in the switching performance of the AGD is limited due to the feedback system bandwidth. In this paper, a high bandwidth current feedback type power operational amplifier is applied as the gate drive circuit. Switching characteristics of the conventional resistive gate driver and AGD are experimentally investigated via a double pulse test setup. The switching setup condition is 700 V / 80 A. This paper describes the development of the AGD circuit and experimental results. The over-shoot and ringing of the Vds and Is are reduced using the AGD. Moreover, the switching loss is simultaneously reduced.

Herein, we propose a control method for a single-phase active filter composed of a universal smart power module (USPM). The USPM is a modularization technology concept that comprises various power conversion systems. Depending on the application, the USPM is a full-bridge inverter with a wideband controller and filter, and the power converter is constructed using several USPMs. In this study, the target system was an active filter composed of modules connected in series or parallel to accommodate arbitrary voltage and current capacitances. The proposed method solves the communication delays between the master and slave controllers owing to the distributed control in wireless communications and the interference problem caused by multiple USPM connections. The experimental results of the steady-state response showed that despite the communication delays, the total harmonic distortion (THD) of the input current was improved by up to 63.0%, and the power factor was 0.997. Moreover, load fluctuation experiments confirmed that the system transitioned to a steady -state and operated stably by updating the command value of the slave controller for the first time after the load fluctuation. The harmonic current elimination can be realized as an active filter, and the effectiveness of the proposed method was confirmed.

There is an increasing interest in powering the subsea loads, such as subsea motor drives, from renewable energy sources, either from the shore or offshore. Due to the long distance from the motor controller to the motor, the use of sensor cables causes electromagnetic interference (EMI) and noise problems in the position information signals. Hence, the sensorless operation of subsea drives becomes important. In addition, variations in system parameters due to changes in operating conditions can result in the deterioration of the performance of drives, and may even lead to unstable operations. In this paper, a closed-loop observer-based method is proposed for estimating the speed and inductances of the equivalent system, which includes a transformer, cable, and motor inductances. The proposed estimation scheme is validated using MATLAB(2020a)/Simulink and Typhoon hardware-in-the-loop for a 500 kW, 4.2 kV interior permanent magnet synchronous motor (IPMSM).
