The air gap and thickness of the ferrite core are determined considering the core saturation and leakage magnetic field. The maximum value of the simulated magnetic flux density at the distance of 200 mm away from the charger is 2.28 mG and the simulation result of the power transfer efficiency is approximately 99.5%.

Inductive Coupling has shown to be a good technique for proximity and wireless power transfer in general, because it permits the easy use of impedance matching and resonance circuits. An important potential application is powering Integrated Circuits (ICs) from a PCB (Printed Circuit Board) without using conductive pins. While using ferromagnetic core materials improves coupling, conductive non-ferromagnetic ones like most IC's substrates, decrease coupling and ICW Power Transfer performance. In this paper we developed a simple theoretical model for ICW power transfer and compared it with 3D Electromagnetic simulations of an inductive link system to ICs. The results show that enough power can be supplied to very low power consumption ICs. As this technique can be also used to perform wireless communications, it opens the possibility to design ICs without pins at all.","PeriodicalId":143468,"journal":{"name":"2013 IEEE Wireless Power Transfer (WPT)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132080409","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}

For maximizing power transfer efficiency, design of a source coil and optimal load impedance are achieved based on circuit analysis and mutual inductance calculation. For verification, a WPT system of a transmitter and three receivers is fabricated. The fabricated WPT system can obtain reflection coefficient of under -11 dB for the maximum three receivers at once by using a circular single loop coil without capacitance compensation or additional impedance matching circuit. The simulated results show that the WPT system using the proposed method has more than 85% efficiency regardless of the number of receivers while efficiency for the conventional method is severely changed according to the number of the receivers. Measured results of the proposed method are consistent with calculation results.","PeriodicalId":143468,"journal":{"name":"2013 IEEE Wireless Power Transfer (WPT)","volume":"88 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120874116","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}
