This consists in minimizing coil losses represented by proximity and eddy currents losses. For this purpose, specific geometric parameters characterizing spiral coils are shown to have a direct impact on increasing such losses. As a result, to minimize proximity effect, high ratios between the interspace separating two adjacent traces and the trace width are recommended to be used. In addition, to reduce eddy current losses, an empirical equation is developed to determine the optimal inner diameter sizes of the coils. The obtained numerical results confirmed that, using the proposed design constraints, the quality factor of the coils improves by 40 % in average with only 12 % decrease of the coil inductance value. Analytical formulation of the coil quality factor is obtained. Comparing analytical to simulation results, the obtained errors are reduced from 43 % to only 5 % when the recommended design constraints are applied.","PeriodicalId":113182,"journal":{"name":"2016 IEEE Wireless Power Transfer Conference (WPTC)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122181870","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 this work, a WPT receiver system integrated on a silicon chip is proposed to maximize the efficiency of the system. The presented chip is produced in a low cost standard 130 nm CMOS process with a high voltage extension. This enables the on-chip integration of a full bridge rectifier with 12V power MOSFETs. A prototype system, designed for the use in mobile applications, has been developed based on the Qi standard specifications. Different control strategies for the rectifier have been implemented and compared regarding their impact on the overall receiver system efficiency. The fully-active rectifier control technique enables the WPT system to decrease its losses and hence increase the system efficiency by more than 16% when compared to a passive approach. The experimental results confirm that the presented system is able to obtain a system efficiency of up to 88% at an output power of 1.8W.","PeriodicalId":113182,"journal":{"name":"2016 IEEE Wireless Power Transfer Conference (WPTC)","volume":"221 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131427197","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}

Therefore, we analyzed the operation of a rectifier circuit by considering the time constants.
