Based on AMPÈRE'S law for straight currents, the contributions of individual coil elements are calculated and summed up. The result is a universally applicable expression for the total magnetic field depending on the geometric and electric parameters of the system. Further analysis reveals the existence of an optimal distance between primary and secondary side at which the magnetic flux density is maximized. This optimal distance is derived empirically, showing a linear dependency on only the spacings between the wire elements. The results in this paper expand the theoretical foundations and contribute to further optimization of three-phase wireless power transfer systems.","PeriodicalId":192132,"journal":{"name":"2020 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116835999","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}

Dynamic IPT systems enable in motion charging of EVs hence reducing the range anxiety with operating an EV. Constant power delivery in dynamic IPT systems is a challenge due to the coupling variation between the ground assemblies (GAs) and the vehicle assembly (VA). Typically magnetic coupling decreases when the VA is located between two GAs resulting in reduced power transfer. This paper proposes a new GA geometry to reduce magnetic coupling variations during pad transitions. The proposed GA (Booster Coil) is designed to transfer 10 KW to a SAE J2954 WPT3Z3 VA and 30KW to a newly designed VA, respectively.

CPT is based on electric field coupling, but it would be useful to analyze the magnetic field distribution too to understand how power is transferred across the coupling plates. This paper presents a fundamental study of electric and magnetic fields between two coupled plates for capacitive power transfer. Methods for measuring the electric and magnetic fields are proposed based on general theoretical analysis, followed by field simulation studies using CST (Computer Simulation Technology) for comparison. Both simulation and practical results show that the electric field magnitude is approximately constant in the middle area of the two coupled plates, but it gets higher near the edges of the coupled plates due to the fringing effect, forming an hourglass shape between the plates. It is also found that the measured magnetic field inside the plates is very low and increases gradually when the test point is placed close to the lead wires of the power supply. The practical measurement results are in a good agreement with CST simulation. The findings regarding the electric and magnetic field distributions from this research are useful for investigating the power transfer mechanism and guiding the practical capacitive coupling design of a CPT system.","PeriodicalId":192132,"journal":{"name":"2020 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"96 38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129312858","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 horizontal flux approach is selected to implement the proposed system, taking advantage of optimization, compared to the system with the vertical flux approach. To overcome the limitation of the approach and enhance the performance, the following three methods are introduced. The permeability of the transmission medium, which is related to the transfer efficiency, is increased by using ferrite. Also, winding multiple transmitter coils is presented to improve uniformity. Finally, adjusting the structure of the transmitter coils raises the intensity of the net magnetic field. By a combination of these methods, average efficiency is observed as 81.3% with low standard deviation, indicating the system has uniformly high transfer efficiency all over the plate. Consequently, the proposed system demonstrates the feasibility of the WPT system in which the receiver can be located freely.","PeriodicalId":192132,"journal":{"name":"2020 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131001253","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}

Theoretical modeling, analysis, and simulation studies are carried out by considering various parasitic parameters and gate-drive setups to investigate their impacts on the system performance. The research shows that these components can significantly affect system operational frequency, power transfer, and efficiency. Nonetheless, the parasitic and gate-drive speed up capacitances can be effectively used for tuning the primary circuit at a few MHz.
