However, as the number of available topologies increases and engineering demands vary, these methods are increasingly unable to provide optimal recommendations. To address this limitation, the present study presents an automatic optimization topology recommendation method (AO-TRM) for DC-DC converters that can accommodate a broad range of engineering requirements. The proposed method begins by identifying precise engineering requirements and then progresses through three key stages: topology generation, analysis, and recommendation. Two engineering applications are used as case studies to validate the effectiveness and capabilities of the proposed AO-TRM. From a pool of 1 186 topologies, the proposed method successfully identified and recommended optimal topologies based on specific requirements. Finally, experimental results are presented, demonstrating the capability, efficiency, and cost-effectiveness of the proposed method.","PeriodicalId":36428,"journal":{"name":"Chinese Journal of Electrical Engineering","volume":"11 2","pages":"235-250"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11077896","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144597747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study systematically reviews high-impact literature from the past five years, analyzing interdisciplinary progress and key challenges in European HES research. The findings reveal significant regional disparities: photovoltaic systems dominate in Southern Europe, thermal energy storage optimization is prioritized in the North, while Eastern Europe retains its reliance on traditional energy. Policy regulations, economic incentives, and sociocultural factors drive the deployment of HESs beyond the pilot stage. System optimization is increasingly utilizing hybrid energy storage and artificial intelligence-driven controls to enhance economic viability and self-sufficiency. Although HESs contribute to emission reductions and improved air quality, persistent energy equity gaps require targeted policy interventions. Current research limitations include scarce long-term empirical data, limited cross-scale modeling, and inadequate policy synergy assessments. Future studies should prioritize multienergy system integration, digital twin applications, differentiated incentive frameworks, and multidimensional fairness assessments. By synthesizing insights from energy engineering, economics, and environmental sciences, a theoretical framework for the synergistic evolution of the HES technology, policy, and society is proposed. This framework offers a knowledge map for scholars and evidence-based guidance for policymakers and supports the HES transition toward integrated sociotechnical energy systems, providing insights relevant to global energy democratization.","PeriodicalId":36428,"journal":{"name":"Chinese Journal of Electrical Engineering","volume":"11 2","pages":"38-62"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11077901","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unavoidable misalignments can result in changes in system parameters, thus affecting charging performance. A novel diagonally crossed solenoid magnetic coupler (DCSMC) is developed as a solution. The DCSMC integrated into a wireless power transfer (WPT) system with a hybrid topology enables superior misalignment tolerance in the X, Y, Z and XY diagonal directions while maintaining load-independent voltage output characteristics. A simplified parameter design method is developed to optimize the misalignment tolerance performance of a hybrid WPT system in multiple directions. Finally, a hardware prototype of a WPT system is constructed with an operating frequency of 200 kHz and a power of 200 W. The experimental results show that the hybrid WPT system, operating under loads from 40 Ω to 80 Ω, can tolerate misalignments of ±90 mm (40.9%) in both the <tex>$X$</tex> and Y axes, maintaining as small as a 5% fluctuation in output voltage.

However, their power supply has become a significant factor limiting their overall performance. A power delivery module, known as a voltage regulator module (VRM), is required to provide high voltage, low current, and a fast transient response to meet microprocessor demands. An interleaved parallel-buck converter is suitable for VRM applications. Selecting an appropriate control strategy for the interleaved converter can help achieve high precision and fast response, thereby optimizing performance. First, the operating principles of interleaved parallel converters are analyzed. The relationship between the number of phases and conversion efficiency is also examined. Subsequently, commonly employed control techniques for interleaved converters are reviewed, discussing their respective advantages and limitations, along with an analysis of their suitability for phase-shedding strategies. A phase-shedding technique for interleaved converters is then introduced. Finally, the shortcomings of current control approaches for interleaved buck converters are outlined, and potential future research directions are suggested.

However, LSPMSMs are associated with synchronization difficulties when starting in cases of high inertia, heavy loads, or supply-voltage sags. Models with lumped parameters and parameter identification are used to study the starting processes. A novel approach for identifying the parameters of an LSPMSM is presented based on reduced experimental data that only include the recording of oscillograms of instantaneous currents and voltages when starting the LSPMSM from an idle state. The parameters of the lumped model are determined using the Nelder-Mead method while minimizing the root-mean-square error between the experimental and calculated waveforms. Multiple starts under different initial conditions are considered owing to uncertain initial conditions, and the initial conditions are excluded from the parameter space of the objective function. The proposed method is used to identify the parameters of a commercially available 0.55 kW, 1 500 r/min LSPMSM sample. The results obtained by modeling the starting processes of the LSPMSM using the identified parameters are similar to the experimental results.","PeriodicalId":36428,"journal":{"name":"Chinese Journal of Electrical Engineering","volume":"11 1","pages":"206-217"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10955300","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143792920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the uncontrollable characteristics of DRUs, a grid-forming (GFM) strategy for wind-turbine converters is necessary to support offshore AC voltage and frequency. However, the active power-synchronization control in traditional GFM converters is unsuitable for DRU-based GFM converters. Thus, the stability issue for DRU-based HVDC systems involving DRU-based GFM and grid-following (GFL) converters has not yet been addressed. To solve these issues, this study begins with the characteristics of a DRU-based HVDC system and presents a control scheme for DRU-based GFM converters for power synchronization. Subsequently, the dq-frame impedance model of the DRU-based GFM converter is proposed for the stability analysis of the entire HVDC system.

These advantages include significant fuel savings, reduced noise emissions, and extended engine lifespan. However, VSGs have a major drawback: their high manufacturing cost owing to the expensive permanent-magnet generators (PMGs) commonly used in these generators, as well as the large size of the power electronics section, which has the same power rating as the generator itself. A solution to reduce the initial investment cost by introducing a two-regime generator (TRG) is proposed. The first mode operates at a constant speed for loads exceeding 50%, without the need for a converter. The second mode operates at variable speeds for loads below 50% using a converter that reduces its power by 50%, thus decreasing the investment cost. Additionally, the cost can be further reduced by replacing the PMG with a brushless synchronous generator. The controller employed in this study is a two-loop proportional-integral-derivative controller that exhibits favorable dynamics and compensates for dead times and parameter variations. TRG have shown a significant reduction in cost compared to VSG while retaining the advantages of the latter.","PeriodicalId":36428,"journal":{"name":"Chinese Journal of Electrical Engineering","volume":"11 1","pages":"194-205"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10955297","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143792908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
