Therefore, the control performance of the PMSM drive is crucial for the EPS system's overall performance. The position measurement angle error (contains measurement delay angle and periodic angle error) plays a significant role in PMSM drives, especially when the motor is rotating in the flux weakening (FW) region. In this paper, the impact of the position angle error on the performance of PMSM drives for EPS across a wide speed range is thoroughly examined. The effect of the measurement delay angle is analysed by considering the voltage and current constraint boundaries of the motor at different rotation speeds. Then, calibration and compensation of the position measurement delay angle are presented. Furthermore, the impact of the periodic angle error on current/torque ripple has been elaborated, and a sensorless control scheme is proposed to mitigate the current/torque ripple caused by such periodic error. According to the experimental results, it has been determined that the motor can operate stably over a wide speed range with an appropriate compensation of the measurement delay angle, and the current/torque ripple caused by the periodic angle error can be effectively eliminated with the proposed sensorless control scheme. As a result, it is confirmed that the analysis and discussion, as well as corresponding compensation methods, demonstrated in this paper can improve the steering feeling of the EPS.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"20 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.70156","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147696268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, jitter injection has become a common practice in system reliability test to evaluate timing robustness under realistic operating conditions. In the past research, only random jitter injection was implemented through phase interpolation techniques. To thoroughly investigate the impact of jitter on signal transmission, this study introduces an innovative jitter injection scheme based on phase adjustment and jitter decomposition principles. Specifically, this paper utilised a direct digital synthesis (DDS)-based jitter synthesis technique and a jitter transmission model in phase-locked loop (PLL) to realise a more complex jitter injection. This integration enables accurate injection of different jitter components in the amplitude spectrum from 0 to 2UI in high-speed SerDes systems. To validate the effectiveness of the proposed scheme, a high-speed serial link test platform was developed, which utilises the novel jitter injection method to characterise critical signal metrics, such as eye diagrams and distribution histogram. Experimental results demonstrate that the proposed scheme effectively replicates both random and periodic jitter present in communication links, thereby providing robust technical support for the design and optimisation of high-speed serial link systems.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"20 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.70152","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147696266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing battery charging strategies typically exhibit low voltage and high current during the initial charging phase followed by high voltage and low current during the later phase. Under these operating conditions, achieving zero voltage switching (ZVS) for all DAB switching devices is challenging, which limits the efficiency and overall performance. To address these limitations, this paper adopts a Neutral-Point-Clamped H-bridge (NPC-H) DAB topology to mitigate voltage stress on the input-side switches. For both charging and discharging scenarios, a direct current control method is proposed using the output current as the primary control variable. Additionally, a Natural Soft-switching Extended-Phase-Shift (NSEPS) strategy is introduced to optimise current stress while leveraging natural soft-switching, ensuring efficiency optimisation across the entire charging cycle. Simulation and experimental results validate the theoretical analysis demonstrating a peak efficiency of 97.52%.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"20 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2026-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.70159","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147666232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
