These circuit models don't correspond to the physical phenomenon of the load part, and the design guidelines of the system have not been established yet. Although there are methods of repeating electromagnetic field simulation to each application and obtaining a converged solution by trial and error, it takes lots of time and is inefficient. This paper proposes an equivalent circuit corresponding to the magnetic flux of IH load part, in order to clarify it. Moreover, a coupled analysis of electric circuit and IH load is carried out. This enables more detailed analysis of an IH load, and it was derived that high power utilization rate is realized in the parallel resonance mode by the simulation and the experiment.","PeriodicalId":434417,"journal":{"name":"2018 IEEE International Meeting for Future of Electron Devices, Kansai (IMFEDK)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116918398","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}
