The proposed design has a similar functionality with the typical Tesla coil where it is able to produce medium voltage with high frequency current at the secondary circuit side. The significant part of the proposed design is that it is without alternating current voltage at the input voltage. The design only needs a low direct current voltage as an input for the primary circuit. According to the Pspice simulation, it proved that the proposed design has the capability to step up the energy and voltage at the secondary winding at least fifty times greater compared to the input voltage. The miniature Tesla coil that has been proposed in this paper is recommended to be use for advance studies particularly on wireless energy evolution.","PeriodicalId":6419,"journal":{"name":"2010 International Conference on Electrical and Control Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75759816","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}
