Contrary to previous WPT systems for RPEVs, the proposed U-WPT can also be used for pick-ups fabricated by the SAE J2954 standard for stationary charging. The proposed U-WPT adopts a new coreless power supply rail to increase its operating frequency from the conventional level of 20 kHz to 85 kHz, as specified in the SAE J2954 standard. With the adaptation of U-WPT, EVs in the future will simply be called wireless electric vehicles (WEVs) regardless of whether they use stationary or dynamic charging systems. A detailed comparison between coreless and with-core power supply rails is thoroughly made, with the results verified in simulations and experiments. This comparison shows that, with the same power rating, the proposed coreless power supply rail is superior to the conventional with-core power supply rail due to its low cost, less insulation voltage stress, lack of core loss, and only slight sensitivity to lateral misalignment, mitigating the condition of less induced voltage.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"15 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":"129538208","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 AVFC is fulfilled with two diodes, one integrator, and one subtractor to sense the voltage variation among the current regulators and then to generate an adaptive reference voltage. According to the reference voltage, the output voltage of the boost converter is automatically regulated, so as to keep a minimum voltage on the current regulator and maintain the required LED-string current. A prototype driver implemented with 0.35-μm 2P4M CMOS process validates the proposed technique. The simulation result shows that the output voltage of the boost converter is dynamically adjusted to compensate for the voltage alteration on the current regulators.","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":"129801110","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}
