Chronic problems such as low uniformity of magnetic field and geomagnetic disturbance of conventional Helmholtz, Merritt, Rubens, Lee-Whiting, and Tetra coils can be significantly mitigated by the proposed uniform DC magnetic field generator (UFG). Different from the previous air coils, the proposed UFG adopts a core-cage so that a strong and uniform DC magnetic field distribution can be generated inside the cage and that the UFG may be quite magnetically robust to ambient changes such as geomagnetic field and ferromagnetic objects. Design procedures for the UFG are fully established. Detailed designs of the UFG for magnetic field generation, enhancing uniformity, and geomagnetic cancellation are provided. Experiments for a prototype UFG of 30 cm × 30 cm × 30 cm size showed that the geomagnetic field inside the UFG was significantly attenuated by - 21 dB while the DC magnetic field uniformity (<; 10°) was achieved over 81 % of the total volume of 27,000 cm3.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115578597","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}

Firstly, a novel two-stage startup control sequence is proposed considering the topological differences compared to the traditional half-bridge MMC-HVDC system. Then the ride-through strategies of the hybrid system under severe dc-side faults including single pole to ground fault and permanent pole to pole short circuit fault are proposed. Using the proposed schemes, under single pole fault, the dc power, dc current and the dc-link voltage are reduced to guarantee the maximum power transfer and protect the semiconductor devices and dc transmission line from over currents. Also, under pole to pole fault, the hybrid system can cut off the dc short circuit current by the dual converters of both sides and is ready for power recovery after fault cleared. The effectiveness of the proposed strategies are validated by a two-terminal reduced-size 21-level hybrid MMC-HVDC model on PSCAD/EMTDC.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126121437","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}

However, physical misalignment between the magnetic couplers of BD-IPT systems used in EVs are unavoidable and introduces variations in self-inductance, leakage inductance and mutual inductance. These variations invariably detune the compensation circuits, thus significantly increasing losses and affecting the power throughput. This paper proposes a hybrid BD-IPT system, which combines a parallel tuned inductor-capacitor-inductor (LCL) network and a series tuned capacitor-inductor (CL) compensation network to provide a constant power transfer over a wide range of spatial displacements. A mathematical is developed to investigate the behavior and the sensitivity to variation in parameters of the proposed hybrid BD-IPT system. The validity of the mathematical model has been verified using simulated results of a 3.3 kW hybrid BD-IPT system. Both theoretical and simulated results are presented to show that a constant power throughput and an improved efficiency can be achieved over a wide range of horizontal and vertical displacements.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128075319","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}
