The switching frequency is automatically tracked through designing the start-up circuit to monitor the zero-crossing of the resonant network voltage and taking the zero-crossing as the condition to drive switches conducting alternatively to ensure that the system is in resonance state. The self-oscillating controlling principle is introduced, the energy transfer process of the self-oscillating push-pull system based on parallel-series compensated topological is analyzed, and the main circuit parameters method of the system is deduced. Experiment results show that the theoretical analysis and the proposed method are valid and feasible.","PeriodicalId":242505,"journal":{"name":"2017 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128161279","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 shifting shell is a metamaterial device proposed according to transformation optics. It can be applied in a wireless power transfer system by covering the coils to move them closer in magnetic field and enhance the mutual inductance between the coils. However, the shifting shell is kind of bulky to enclose the whole coil. In this paper, we propose another application of the shifting medium — to enclose the cross-section of the coil with the shifting layer. In this way, the coil is not only shifted but also expanded so that the magnetic coupling could be enhanced to a larger extent. Moreover, the shifting layer is more compact than shifting shell.","PeriodicalId":242505,"journal":{"name":"2017 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134434503","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}

Sometimes the user sets the tolerance of the relatively larger transverse offset as the primary aim, but they never give up high efficiency. This paper theoretically analyzes the effects of the ratio between AC internal resistance of coil and mutual inductance on the transfer efficiency in the LCL WPT system, and then, we get the minimum permitted value of the mutual inductance with specific efficiency in a given WPT system. In addition, we also get the permitted degree of the transverse offset under different separation distance between coils. Finally, we find that decreasing the AC internal resistance is beneficial to increasing the transverse offset. Experimental results verify the theoretical analyses.","PeriodicalId":242505,"journal":{"name":"2017 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123326841","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 has the potential to be highly efficient, low cost, and less susceptible to alignment issues. One major challenge hindering its widespread use is the high voltages found between the capacitive electrodes. Due to this, bipolar (dual, plus/minus electrode) techniques are predominant in literature, as unipolar (one electrode) techniques generally require even higher voltages for operation. Here we present the use of quarter wave resonators as one method to reduce electrode voltages while maintaining efficient energy transfer in a unipolar capacitive geometry. An accurate theoretical model is given based on standard circuit theory. Experimental verification of power transfer over a 5 m by 0.3 m surface is presented where various loads are placed on the system and changing phase parameters are measured.","PeriodicalId":242505,"journal":{"name":"2017 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127268522","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}
