Based on a convergent charging scheme, two new algorithms are proposed, by combining the solution of the Fermat point problem with the advantages of the greedy algorithm. Different from the existing solutions where the charging base stations are restricted on some special locations (like grid points), the charging base stations are more flexible in new algorithms. Instead of setting a charging circle, the specific variation of the power transfer efficiency with distance is used in the new algorithms to optimize the number of the charging base stations more accurately. The simulation results show that for different numbers of sensors, the proposed two algorithms can get a smaller number of base stations. Furthermore, the convex vertices priority algorithm has the advantage of less candidate base stations and consequently less time consuming.","PeriodicalId":148719,"journal":{"name":"2019 IEEE Wireless Power Transfer Conference (WPTC)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123133846","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}

Main features of the studied circuit include: 1) power transfer with high efficiency and low sensitivity to misalignment between coils, 2) simultaneous data transfer with high bandwidth, and 3) without the requirement of an extra DC-DC converter to control the output power. Having a controllable quality factor, this converter represents superior performance compared to conventional WPDT circuits. Unlike class E converters, this circuit employs a small input inductance, which results in better data transmission performance. Experimental results of a 1 MHz prototype are presented to verify its functionality.","PeriodicalId":148719,"journal":{"name":"2019 IEEE Wireless Power Transfer Conference (WPTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121080952","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 main challenge of this paper is that the MR-WPT with the Automatic Tuning Assist Circuit (ATAC) enables a multiple FSK communication toward moving objects. The proposed system with ATAC can maintain the resonant state even though the driving frequencies of the transmitter slightly differ from the resonant frequency. Therefore, this characteristic means that it enables simultaneous transmission of power and FSK modulated data at multiple frequencies without a sharp decline in power transmission efficiency. The proposed system is implemented, and it shows double bit data transmission at the same symbol rate with multiple FSK modulation.","PeriodicalId":148719,"journal":{"name":"2019 IEEE Wireless Power Transfer Conference (WPTC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128975046","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}

In addition, the Automatic Zero-Voltage Switching allows efficient Class-E operation over a range of resonant frequencies. This wire structure may be cut to length and reshaped to fit areas of different size without the need for adaptive impedance-matching.
