Firstly, the structure of modified rotor, which is used to reduce the core loss at high speed, is given and the analytical model for the calculation of reference stress of rotor core with or without central bridge is established correspondingly. Then, an accurate function of stress concentration factor, which can consider the effects of rotor size, number of poles and polar-arc to pole-pitch ratio, is further developed to improve the accuracy of MMS for central bridge. A static core tensile test method is proposed, which can avoid the danger caused by high-speed rotation and indirectly verify the accuracy of the proposed model and finite element analysis (FEA) results. Finally, the influence of temperature changes on the mechanical properties of core is also studied, which provides a theoretical basis for the temperature-stress field coupling analysis of HSIPM motors. Compared with FEA, the proposed model can consume less time with the acceptable accuracy, which brings convenience to initial design and optimization of HSIPM motors.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 1","pages":"67-76"},"PeriodicalIF":4.2,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the rich harmonics lead to the high loss and low efficiency of motor system. To suppress the harmonic loss, a stator modular design concept is proposed for fractional slot concentrated winding PMV motor. First, the precondition that the motor meets the stator modular design is derived, and according to this, a variety of options for modular design are expounded, including uniform or hybrid modular designs and tooth or yoke modular designs. Then, the harmonic distributions of PM field, armature reaction field, and harmonic loss of PMV motor with fractional slot concentrated winding (FSCW) are discussed. Based on analytical analysis and finite element analysis, the inhibitory effect of modular design method on the amplitude of the harmonic with low pole pair number in the motor armature reaction field is verified. Through comparison, it is found that the proposed stator modular design method can suppress motor losses without reducing output performance. Finally, a PMV motor with modular stator is processed and tested to verify the analysis.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 1","pages":"56-66"},"PeriodicalIF":4.2,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article models the short circuit fault transient in a GaN HEMT half-bridge configuration including parasitic elements, based on the state-variables in the circuit and the datasheet parameters. Faults at higher bus voltages result in increased instantaneous power loss, which in turn lead to higher junction temperatures. This results in reduced SCWT for the device. The model is further used to estimate the fault clearing time for different dc bus voltages. A scheme for ultrafast over-current protection of GaN HEMTs is presented. The protection scheme employs a non-intrusive PCB-embedded Rogowski Coil (PCB-RC) based current sensing technique for sensing the device current. Experimental results with the dc bus voltage set to 400 V, demonstrating the protection of the device subjected to a hard switched fault (HSF) are presented. The protection response time is reported to be 38 ns, which is less than the estimated fault clearing time.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 1","pages":"549-559"},"PeriodicalIF":4.2,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143361426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This level of waveform distortion in the electric power system, and its impact on the operation of energy delivery infrastructure, can no longer be neglected in high-voltage power systems. In this paper and beyond the state-of-the-art, an adaptive frequency-domain-based harmonic power flow (HPF) analytic is proposed for power systems with voltage source converter (VSC)-based high-voltage direct current (HVDC) transmission lines. The proposed algorithm uses a two-layer loop to estimate the initial modulation variables of the VSC. It updates the initial variable by calculating the first-order harmonic, ensuring that the adaptive effect of the HPF solution remains consistent regardless of any changes in the firing angle. The hybrid nonlinear model is applicable to both fundamental and harmonic power flow analyses at the point of common coupling, and also under the geomagnetic disturbance (GMD) events. To demonstrate the effectiveness of the proposed HPF algorithm in hybrid AC/DC transmission systems, a modified pulse width modulation (PWM)-controlled bi-terminal VSC-HVDC transmission system based on the IEEE 30-bus test system is used as a testbed. Simulation results and numerical analyses verify the effective performance of the proposed solution as compared to the conventional practices.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 1","pages":"1006-1018"},"PeriodicalIF":4.2,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the SoC estimation accuracy decreases significantly when the cell balancing circuit is activated, which will further degrade the cell balancing performance. In this paper, we propose a switched systems approach to address this issue by integrating the two problems together in a unified switched systems framework. The proposed method consists of two stages: balancing-aware SoC estimation and observer-driven cell balancing. In the first stage, we propose a switching sliding mode observer to estimate the SoC of supercapacitor balancing systems, where two observers are designed for supercapacitors with cell balancing activated or deactivated. In the second stage, a cooperative SoC balancing method is proposed to synchronize the SoC of supercapacitors, which can effectively improve the energy efficiency during the charging process. An experimental platform is established, and the SoC estimation performance and SoC balancing performance are verified with experiment results. Experiment results indicate that the switching sliding mode observer improves the SoC accuracy by 4.96% than its non-switching counterpart and the cooperative balancing method improves the energy efficiency by 8.7% compared with the decentralized balancing method.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 1","pages":"1019-1030"},"PeriodicalIF":4.2,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Single and dual condenser liquid cooled configurations are tested under current levels ranging from 80 Arms to 140 Arms and up to 800 Hz. Comparison between these cooling systems shows the effectiveness of both configurations for AlSi10Mg additively manufactured coils.

Constraints are constructed first by addressing the design of the line-start PMLSM. Then a multi-objective description is established to unify the transient responses, including the damping response and the time response, in the line-start process and the transient optimisation strategy is established via particle swarm optimisation (PSO). With different combinations of weighting functions in the multi-objective expression, optimisation cases are analysed and the optimised design of the line-start PMLSM prototype are experimentally tested. The proposed theory is proved to be a feasible and efficient design method of the line-start PMLSM. Three optimal principles of the line-start mover topology are addressed, in which the damping response is addressed to have more impact on the optimal design of the line-start PMLSM compared to the time response. Meanwhile, a larger number of conductive rungs are proved to enhance the performance during the online starting phase. Trends of the combination between permanent magnets and conductive materials are also derived to optimise the damping response and the time results. These optimal principles can be another contribution for the industrial PMLSMs requiring online-starting capability.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 1","pages":"77-88"},"PeriodicalIF":4.2,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve the inertia and transient support capability of microgrid, a hybrid power supply system composed of an open-winding wound field synchronous generator (OW-WFSG) and an energy storage system (ESS) is proposed. By analyzing the power flow of the system, a synchronous control strategy based on rotor position tracking is proposed to realize the decoupling and control of power. Meanwhile, the analysis of active power support mechanism shows that the ESS with the proposed control strategy has the characteristics of synchronous generator, which achieves further improvement of the grid inertia and frequency support capability. Moreover, to improve the voltage support capability under power grid voltage fault, a winding closure and overexcitation control is proposed, which not only utilizes the high overload capability of OW-WFSG, but also avoids overcurrent damage to the converter. Experimental results verify the effectiveness of the proposed control strategy.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 1","pages":"1043-1054"},"PeriodicalIF":4.2,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
