However, the lack of analytical expressions describing the coupling between AGD parameters and temperature variation limits the broader application of this method, particularly in SiC modules that exhibit complicated device transient behaviors. To address this challenge, a mathematical model of the transient behavior of an SiC module is developed to investigate the relationship among AGD parameters, junction temperature, and switching performance. The analysis reveals that the impact of temperature on switching performance is directly linked to the duration of each gate resistance. Accordingly, a temperature-adaptive AGD for SiC MOSFET modules is proposed. Online junction temperature monitoring is achieved using turn-on delay detection, and the duration of each gate's driving resistance is dynamically adjusted. The proposed temperature-adaptive AGD is validated experimentally using a commercial 1.2 kV/560 A SiC MOSFET at 600 V/200 A. Experimental results across a temperature range of 20°C to 100°C demonstrate that electrical stress variation remains within 15%, while loss variation does not exceed 10%.","PeriodicalId":36428,"journal":{"name":"Chinese Journal of Electrical Engineering","volume":"11 2","pages":"216-225"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11077900","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144597942","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}

Herein, both continuous and stepped skews are considered. It is found that the effectiveness of the rotor skew depends on the load/electric loading and magnetic saturation and is generally inferior in interior PMSMs (IPMSMs) than in surface-mounted PMSMs (SPMSMs). The conventional skew angle, that is, the one on-load torque-ripple periodicity, works well in SPMSMs under light-load conditions. However, when SPMSMs are under heavy-load conditions with significant magnetic saturation or IPMSMs are under all load conditions, an optimal skew angle exists to simultaneously deliver a higher average torque and lower torque ripple than those obtained with the conventional skew angle. This is regardless of whether a continuous or stepped skew is applied. Therefore, a tradeoff between the optimal skew angle, torque production, torque ripple, and load conditions should be considered carefully when selecting skew strategies for different applications.","PeriodicalId":36428,"journal":{"name":"Chinese Journal of Electrical Engineering","volume":"11 2","pages":"188-206"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11077895","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144597926","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}

The corresponding fault diagnosis methods including model, signal processing, and artificial intelligence (AI)-based models are demonstrated separately. Moreover, state-of-the-art designs for fault-tolerant PMSMs are presented and suggested. Advanced control methods for machine failure scenarios are also discussed, which could potentially pave the way for post-fault aerospace operations.

Epoxy-based insulators, as core components, experience significant electric field distortions and consequent flashover faults. Since the 1980s, researchers have focused on utilizing dielectric functionally graded materials (FGMs) to improve the electric field distribution of insulators. The key research on FGMs for GIL/GIS insulators over the past half-century is reviewed. The development from bulk-FGMs to surface-FGMs, and eventually to multi-FGMs are outlined. Bulk-FGMs are typically used in AC systems. These materials provide a more uniform electric field distribution by creating a gradient in the relative permittivity within the insulator's bulk. Surface-FGMs are commonly employed in DC systems, and they regulate the electric field by designing a surface conductivity gradient, thus preventing internal breakdowns that result from bulk conductivity gradients. In practice, GIL/GIS insulators are exposed to complex operating conditions, including AC, DC, and transient voltages, resulting in the development of multi-FGMs. These combine both conductivity and permittivity gradients, thus providing a comprehensive solution for suppressing both dynamic and static electric field distortions. An effective reference for researchers and industry professionals to support the transition of the research on FGM insulators from laboratory studies to practical engineering applications is provided.","PeriodicalId":36428,"journal":{"name":"Chinese Journal of Electrical Engineering","volume":"11 2","pages":"150-164"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11077893","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598022","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}
