Current research lacks a unified system model to describe the operation mechanism and power characteristics under arc faults. This paper proposes an equivalent model of PV-boost power generation system based on series/parallel arc constraints. Firstly, by coupling the arc equivalent model in the PV model, the output characteristics of the PV system in normal and fault states are obtained. Then, by adding the arc link in the power conversion and control model of the PV-boost system, the operation mechanism and power transfer characteristics of the system under two types of arc faults are revealed. Finally, based on the multimodal PV output voltage-current characteristics under arc faults and the voltage-current characteristics at the input end of the boost under maximum power point tracking control, a specific fault identification and classification method for series/parallel arcs is designed, which is easy to implement in engineering and based on the degree of hazard. The feasibility of this scheme is verified.","PeriodicalId":100339,"journal":{"name":"CPSS Transactions on Power Electronics and Applications","volume":"11 1","pages":"53-66"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11431139","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147620954","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}

Electromagnetic compatibility (EMC) is one of the critical performance indicators for CLLC circuits. To investigate the conducted common-mode (CM) EMI characteristics of the CLLC converter, a CM EMI equivalent circuit model was established based on the noise transmission mechanism, and an equivalent model of the CLLC converter was derived, clarifying the noise source characteristics and the key CM noise transmission path impedances. The noise source characteristics under different operating conditions were analyzed to reveal the CM noise behavior in each condition. Based on this analysis, a symmetry-based design method for optimizing the CM EMI performance of the CLLC converter was proposed, and the impacts of resonant inductor and capacitor symmetry were examined. The correctness of the CM characteristic analysis for the CLLC converter is verified through simulations and experimental tests. By constructing a symmetric resonant cavity structure, the CM noise is attenuated by 20–30 dB, which further validates the feasibility of the symmetric structure-based optimization design method.","PeriodicalId":100339,"journal":{"name":"CPSS Transactions on Power Electronics and Applications","volume":"11 1","pages":"91-100"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11351961","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147620961","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}

However, effectively translating the progress made in such research into educational content presents a formidable challenge for both researchers and educators alike. An example of Google Little Box Challenge by university team is introduced at first. Then, this article endeavors to showcase an attempt at integrating the latest research advancements in the domains of power electronics and motor drives into education, with the innovative series-end winding motor drives (SWMD) serving as a prime illustration. Recent breakthroughs in topology, control algorithms, and reliability have been swiftly adopted by students in the development of high-performance drives for applications such as drones, electric vehicles, and magnetic bearings. These efforts have culminated in remarkable achievements and significant milestones in various competitions. This study proposes a methodology for bridging the gap between recent research progress and education, particularly tailored to meet the needs of students possessing strong capabilities and intrinsic motivation. The case study centered around the novel SWMD not only elucidates the educational approach but also demonstrates its tangible outcomes as manifested through diverse student contest implementations.","PeriodicalId":100339,"journal":{"name":"CPSS Transactions on Power Electronics and Applications","volume":"10 4","pages":"360-369"},"PeriodicalIF":0.0,"publicationDate":"2025-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11273112","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145963451","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}

However, the design of these controllers strongly depends on the available knowledge of the controlled plant, which often leads to the lack of robustness owing to model-dependent nature. To take account of the defect, this work aims to provide a control framework that combines intelligent data-driven-based control protocol with the deep rein-forcement learning technique for electrical drives. Specifically, the two key features of this developed control framework that, first, a data-driven control architecture along with deep rein-forcement learning technique that embedding the features of the agents' inputs is developed to enhance the performance, second, the environment for the current agent is reformulated so as to avoid mutual interference between the two agents (controllers) in training for both speed and current in a dual-loop system. Finally, we demonstrate our solution and highlight its superiority on a case study, and the results presented are promising and motivate further research in this field.","PeriodicalId":100339,"journal":{"name":"CPSS Transactions on Power Electronics and Applications","volume":"10 4","pages":"370-378"},"PeriodicalIF":0.0,"publicationDate":"2025-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11273113","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145963450","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 fault-tolerant methods which require topology reconstruction have the disadvantages of additional cost and unreliability. It is of great significance to study the no-reconstruction fault-tolerant (NFT) method, which only changes the control algorithm. In this paper, a novel NFT method is proposed for induction motor (IM) drive, which consists of the two-mode control algorithm and the algorithm transition strategy. In the healthy mode, conventional model predictive flux control (MPFC) is adopted; in the tolerant mode, a novel MPFC algorithm is proposed to eliminate the effect of the fault power switch by setting the reference fault phase current as zero. The two modes alternate in each current cycle. An algorithm transition strategy is proposed for the smooth transition of two modes, which has the ability to revert to healthy operation even if misdiagnoses occur. The proposed NFT method can significantly reduce the speed oscillation after the fault occurs, and experiment results verify its effectiveness.","PeriodicalId":100339,"journal":{"name":"CPSS Transactions on Power Electronics and Applications","volume":"10 4","pages":"423-431"},"PeriodicalIF":0.0,"publicationDate":"2025-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11273108","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145963452","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}
