The wireless power transfer system applied in implantable medical devices can reduce the patients\u2019 physical and economic burden because it will achieve charging in vitro. For a deep brain stimulator, in this paper, the transmitter coil is designed and optimized. According to the previous research results, the coils with ferrite core can improve the performance of the wireless power transfer system. Compared with the normal ferrite core, the stepped core can produce more uniform magnetic flux density. In this paper, the finite element method (FEM) is used to analyze the system. The simulation results indicate that the core loss generated in the optimal stepped ferrite core can reduce about 10% compared with the normal ferrite core, and the efficiency of the wireless power transfer system can be increased significantly.<\/jats:p>","DOI":"10.1155\/2016\/2624917","type":"journal-article","created":{"date-parts":[[2016,2,11]],"date-time":"2016-02-11T16:01:29Z","timestamp":1455206489000},"page":"1-8","source":"Crossref","is-referenced-by-count":0,"title":["Optimal Design and Analysis of the Stepped Core for Wireless Power Transfer Systems"],"prefix":"10.1155","volume":"2016","author":[{"given":"Xiu","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Electronic and Communication Engineering, Tianjin Normal University, Tianjin 300387, China"},{"name":"Tianjin Key Laboratory of Wireless Mobile Communications and Power Transmission, Tianjin Normal University, Tianjin 300387, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Electronic and Communication Engineering, Tianjin Normal University, Tianjin 300387, China"},{"name":"Tianjin Key Laboratory of Wireless Mobile Communications and Power Transmission, Tianjin Normal University, Tianjin 300387, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"year":"1999","key":"1"},{"issue":"3","key":"2","first-page":"93","volume":"9","year":"1961","journal-title":"IRE International Convention Record"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1109\/TBCAS.2010.2072782"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/JPROC.2013.2246531"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/tpel.2013.2249670"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/mmw.2002.1145675"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/TIM.2008.925019"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1126\/science.1143254"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1109\/tpel.2014.2310232"},{"issue":"1","key":"18","first-page":"15","volume":"16","year":"1969","journal-title":"IEEE Transactions on Biomedical Engineering"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1109\/tbme.2000.880100"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/8.899680"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/map.2009.5433097"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1109\/tmag.2004.824127"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/tmag.2010.2041433"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1109\/tmag.2011.2147768"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1109\/TMAG.2012.2196263"},{"year":"1999","key":"21"}],"container-title":["Mobile Information Systems"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/2624917.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/2624917.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/2624917.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,7,26]],"date-time":"2016-07-26T09:10:27Z","timestamp":1469524227000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/misy\/2016\/2624917\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016]]},"references-count":18,"alternative-id":["2624917","2624917"],"URL":"https:\/\/doi.org\/10.1155\/2016\/2624917","relation":{},"ISSN":["1574-017X","1875-905X"],"issn-type":[{"type":"print","value":"1574-017X"},{"type":"electronic","value":"1875-905X"}],"subject":[],"published":{"date-parts":[[2016]]}}}
