In addition, the optimal ratio about magnet length and width under same volume is clarified from the perspective of maximization of interlinkage magnetic flux.

Moreover, the proposed coil system successfully removes the transfer null caused by a large misalignment.

Accurate and reliable methods of loss separation are required to identify the most significant machine losses to target for reduction in order to increase the efficiency. Machines made with stators of soft magnetic composites can offer higher power density. However, in such machines, the proximity of the rotor and stator windings to the end-caps may elevate the induced eddy-currents in the endcaps, increasing the machine losses. This study investigates the losses of a 9 slot, 8 pole, 400 W, 3,000 rpm surface permanent magnet soft magnetic composite machine with a bonded rare-earth magnet ring rotor. Using a combination of analytical and finite-element modelling, and laboratory experimentation, the losses are characterised. The methods used to determine and separate the losses are described, and the results are then applied to prediction of the machine efficiency. The loss characterisation methodology presented in this paper can be used to analyse and hence improve the performance of other brushless permanent magnet machines.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132482465","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}

The objective of this study is to reduce the torque ripples in advanced IPMSMs, which cause vibrations and noise, by modifying the rotor structure. First, holes were drilled in the rotor of a double-layered IPMSM, which the authors previously proposed, and their influence on torque ripple was evaluated. Then, dents were formed in the surface of the modified IPMSM rotor, and their effect on torque ripple was evaluated. The torque ripples of the modified IPMSMs are lower than those of the reference model under maximum torque per ampere control and in other current phase angle regions. In addition, at low current, the proposed models reduced the torque ripple from that of the reference model over the entire current phase angle region.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125249577","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}

The bearing performance of SSGB is greatly affected by the groove shape, therefore the aim of this paper is to optimize the groove shape by means of computational fluid dynamics (CFD). CFD simulation results show that the groove width ratio Δ and groove depth h0 have dominant effects on the bearing performance; and that the bearing loss can be reduced by 36.5% with Δ = 0.70 and h0 = 0.02 mm as compared to the SSGB currently used. The prototype SSGB with the optimized shape was fabricated and the actual bearing loss was experimentally tested.

At this point of time, variations in power generation may occur within the range of maximum power point tracking (MPPT) control. If the area with low power generation cannot be bypassed, the overall power generation is reduced. Thus, system operation with high efficiency is expected to be difficult. To cope with this problem, the authors developed a buck-boost MPPT that can be configured as a distributed MPPT. Furthermore, to improve efficiency, a GaN field-effect transistor (FET), rather than the conventional Si FET, was used. In this research, we showed that the MPPT using GaN semiconductors is more efficient than MPPT using Si semiconductors. In addition, it was found that when partial shadows were formed on the PV module, the distributed MPPT could exert higher power generation efficiency than the concentrated type.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121628840","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}

It is often assumed that the magnetic flux density evenly distributes throughout the core and the overall core loss is calculated according to an effective flux density value and the macroscopic dimensions of the cores. However, the flux distribution in the core can alter by core shapes and/or operating conditions due to nonlinear material properties. This paper studies the element-wise estimation of the loss in magnetic cores. FEM has been used to investigate the flux density distribution in the core and the loss has been estimated considering this distribution. Finally, comparative results are shown between the classical macroscopic core loss estimation using effective dimensions and the element-wise loss estimation. The presented work in this paper has been carried out for two common excitation waveforms in power electronics applications, sinusoid and square-wave and for two different core shapes, toroid and E-cores. Results show that ±10% discrepancy should be expected in loss estimation of the core using effective dimensions under both excitation waveforms.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115325859","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}
