The multilevel operation of the proposed 9L-BPFC rectifier lessens harmonic content in the supply current and reduces voltage stress on the power devices. In addition, it can supply single/multiple dc loads at the same time. The series–parallel switching of the capacitors autobalances its voltages for possible load configurations. Hence, it reduces the need for complicated control to balance capacitor voltages and resolve the issue of rectifier instability during dynamic conditions. Moreover, it supports open-circuit fault tolerant operation for middle switches and maintains the same output power under fault conditions as in healthy mode. The operating principle, modulation strategy, device ratings, and capacitor sizing of the proposed rectifier are presented in this article. Finally, the performance of the proposed 9L buck PFC (9L-BPFC) rectifier is examined and verified using experimental results.

Based on this design method, the power equation of the RFDR-PMSM with the modular stator is derived, which reveals the theoretical relationship between the main sizes and the power. In order to simplify the winding process of the modular stator, a fractional-slot concentrated winding is selected for RFDR-PMSM with the modular stator. Then, a 24-slots and 20-poles RFDR-PMSM with a modular stator is designed using the proposed design methodology. Through finite element analysis (FEA), it is found that the design RFDR-PMSM with the modular stator has higher power density and efficiency compared with the traditional RFDR-PMSM with a stator yoke. Moreover, a modular stator structure with a pin connection is proposed to solve the problem that the stator loses effective support after removing the stator yoke. Finally, a prototype of the RFDR-PMSM with the modular stator is manufactured. The back electromotive force (EMF), current-torque curve, and the efficiency map up to 10 kW of the RFDR-PMSM with the modular stator are tested, and the correctness of the finite element model and theoretical design is verified by comparing the experimental results with the FEA results.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"5 4","pages":"1409-1419"},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142438450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To suppress the overcompensation and obtain the faster convergence, neural network timing control and bias correction are also adopted simultaneously.

The widely used SOC estimation method in the industry is the extended Kalman filter (EKF). To explore and analyze the potential use of SOC estimation in a cloud platform, this article develops and conducts a comparative analysis of four SOC estimation methods: EKF, feedforward neural network, gated recurrent unit, and long short-term memory. These models are deployed in two cloud computing infrastructures, and their accuracy and computing time are thoroughly examined in this study. This study concludes that the EKF method is the fastest and most accurate among all considered methods.

This article introduces a fault detection and diagnosis methodology for bearing condition monitoring processes, utilizing the Mahalanobis squared distance (MSD). In the initial phase, a health index, namely MSD, is proposed to accurately indicate the health condition of the spherical bearing in an induction motor based on vibration signals. The MSD serves as a preclassification stage, effectively addressing the issue of data overlap and facilitating the identification of distinct data classes, particularly in cases where nonlinear and non-Gaussian data are prevalent. In the subsequent phase, a deep learning (DL)-based approach utilizing transfer learning is employed for the classification of the labeled dataset by MSD. Three established models, namely AlexNet, VGG19, and ResNet50, pretrained on the ImageNet dataset, are considered. These models are further fine-tuned using scalogram images generated through the application of continuous wavelet transform on the vibration signals obtained from spherical roller bearings. This integrated approach for fault detection and diagnosis is presented and validated using the intelligent maintenance systems bearing dataset. The results obtained demonstrate the reliability and efficacy of the proposed approach in accurately detecting and diagnosing bearing faults. Furthermore, the experimental findings indicate that the proposed approach surpasses existing state-of-the-art methods documented in the relevant literature.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"5 3","pages":"1226-1233"},"PeriodicalIF":0.0,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141583571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PV emulators are essential for power converter testing in PV systems, particularly for grid-tied PV systems, which are among the most paramount inverter-based resources. Certain factors, such as real-time output and simple implementation with high accuracy, should be considered when designing a PV emulator. Conventional PV emulators utilize traditional PV mathematical models and controllers, like the Newton-Raphson (NR) method and PI controllers, respectively. This matter makes a PV emulator unable to reproduce the curve in different conditions because the PI controller is unable to tolerate changing operating points while drastically preserving robust performance with those alterations. Also, NR requires considerable iterations, leading to an intense computational burden. Accordingly, this article proposes a more effective and simple control methodology to optimize the performance of converter-based PV emulators. In this regard, the PV model is based on the single-diode model with five unknown parameters while considering a simple buck converter. This article utilizes the Lambert \u0000<italic>W</i>\u0000 method to solve the exponential equation of the PV model, thus changing an “\u0000<italic>implicit</i>\u0000” function into an “\u0000<italic>explicit</i>\u0000” one. It also reduces the number of iterations; therefore, the computational burden is diminished while maintaining the performance and accuracy of converter-based PV emulators. Also, this article introduces a novel adaptive intelligent fractional-order controller to control converter-based PV emulators. In this strategy, the proposed fuzzy inference system obtains the three coefficients of the controller using Harris hawks optimization and gradient descent algorithm. With an adaptation of the three controller parameters, the performance of the converter-based PV emulator is improved by reducing the tracking error while inducing closed-loop system stability. Comparative simulations and experimental results reveal the effectiveness of the proposed control methodology.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"5 4","pages":"1493-1507"},"PeriodicalIF":0.0,"publicationDate":"2024-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142438503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the common ground, the proposed topology eliminates the leakage current. The voltages of SC are self-balancing without the need for external dedicated circuits or sensors. The operating principle of the proposed topology is described in detail, followed by the design guidelines for sizing SC. The comparative summary highlights the advantageous features of the proposed topology, including fewer components, high gain, self-balancing capability of SCs, lower conduction and switching losses, and near-zero leakage current.
