The core hysteresis permeance model based on the permeance-capacitance analogy is suitable for transformer simulation due to its reasonable energy analogy and strong electromagnetic information representation. However, framework structures and solution methods vary with different hysteresis models, affecting simulation accuracy. This paper comprehensively evaluates three hysteresis permeance models. First, the modeling process via permeance-capacitance analogy is summarized. Building upon existing Preisach and Jiles-Atherton (J-A) models, a static Energetic hysteresis permeance model is established to better reflect microscopic magnetization characteristics. Then, comparative analyses are conducted regarding parameter identification difficulty, parameter quantity, and hysteresis loop accuracy for different core materials. Finally, fixed-step and variable-step algorithms are employed to evaluate solution data distribution, computational efficiency, and simulation stability over multiple cycles. The simulation discrepancies are systematically analyzed considering inherent characteristics of each hysteresis model. © 2025 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"21 7","pages":"994-1006"},"PeriodicalIF":1.1,"publicationDate":"2026-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148247776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although network reconfiguration is a promising approach to address these challenges, it requires system operators to estimate the system states owing to the lack of enough sensors to directly monitor the power-flow conditions in distribution systems. The authors have previously developed a probabilistic state estimation technique that accounts for load and PV output uncertainties; however, this technique did not consider the voltage-control equipment within the distribution system. Therefore, this paper presents a novel network-reconfiguration method that incorporates the control effect of step voltage regulators (SVRs). The proposed method optimizes the SVR output voltage using the probability distribution of the voltage profile in conjunction with the optimal network reconfiguration. Numerical simulations on a modified IEEE 33-bus system model demonstrate that the proposed method reduces distribution power loss while satisfying the voltage-violation probability. © 2025 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"21 7","pages":"1028-1038"},"PeriodicalIF":1.1,"publicationDate":"2026-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148247804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cost function includes current performance, which is transformed into a form that relates only to the phase of the voltage vector while satisfying optimal amplitude. Then, the candidate voltage space is derived based on the preset flexible constraint of the cost function. Moreover, the principles for selecting the optimal voltage vector from the space are presented to reduce the switching frequency of the inverter. With this method, controllable and consistent current performance under various operating conditions can be achieved, while the switching frequency of the inverter is effectively reduced. In addition, the proposed method avoids the use of the weighting factor.

To address the harmonics generated in VVMPC due to the prolonged effective VV action time and current prediction delay, this paper first effectively suppresses the harmonic currents in the x-y plane by pre-synthesizing the VV control set. Then, the hysteresis error in the prediction process is eliminated by utilizing the compensation of the current prediction delay. Additionally, a zero-vector insertion VV duty cycle modulation method is proposed to further suppress the harmonics caused by the over-excitation of the current response. Finally, through experimental comparison with three benchmark algorithms, the suppression effects of the MPCHCS strategy on x-y plane harmonic currents, phase current harmonics, torque pulsations, and speed fluctuations are verified, specifically, the phase current (Total Harmonic Distortion, THD) and x-y plane harmonic current content are reduced by 62.4% and 63.5%, respectively, compared with the VVMPC scheme. © 2025 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"21 7","pages":"1039-1048"},"PeriodicalIF":1.1,"publicationDate":"2026-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148247840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The design tackles the tricky computational challenges of video decoding and text extraction by embedding the Gamma Correction Method (GCM) directly into the video decoder. Furthermore, we develop an upgraded version of the GCM, known as the Optimized GCM, to enhance performance and reduce computational demands. Specialized hardware accelerators handle the computation-heavy parts of the optimized GCM. We then integrate these hardware modules as co-processors alongside the ARM Cortex-A53 processor via an AXI-stream interface. Finally, we tested the entire HW/SW system on the ZCU102 embedded kit. The proposed HW/SW co-design for the optimized GCM slashes processing time by a staggering 96% compared to a software-only implementation of the same approach. Even better, this time-saving boost doesn't sacrifice accuracy, as both methods achieve identical F-Measure values for text extraction. These findings showcase just how effective this HW/SW design is for handling the heavy computational workload of real-time text extraction from videos. They also highlight the potential of combining hardware accelerators with optimized algorithms to improve video processing systems in embedded environments. © 2025 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"21 7","pages":"1075-1084"},"PeriodicalIF":1.1,"publicationDate":"2026-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148247882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, accurately predicting core loss remains challenging due to the non-sinusoidal and multidirectional magnetic flux inherent in the PMA-AFHSRM. To address this, a multi-region layered sampling approach that accounts for rotor dislocation is adopted to analyze the magnetic field characteristics at typical core locations. Based on this, a 3D orthogonal flux decomposition-based loss model is developed, incorporating high-order harmonics, frequency-dependent eddy current corrections, and minor hysteresis loops identified by an improved rainflow counting method (IRCM). The proposed method is applied to a 20 000 r/min PMA-AFHSRM and validated through experimental measurements at various speeds, with finite element analysis (FEA) results included for comparison. The results show that the proposed method achieves a maximum deviation of less than 5% across all tested speeds, demonstrating better accuracy than the FEA. © 2025 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"21 7","pages":"1098-1108"},"PeriodicalIF":1.1,"publicationDate":"2026-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148247772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
