This inverter-fed fluid heating appliance is more acceptable for high-quality heat energy transfer and delivery under a precise temperature control scheme, heat-energy storage and heat exchange processing plants as well as vessel and tank heating plants in the pipeline because of clean processing, high-efficiency, compactness in volumetric size, high-reliability, and best control ability. In particular, the series capacitor-compensated resonant PWM inverter system with a power factor correction and active sinewave line current-shaping functions is introduced for induction-heated pipeline fluid heating appliances in industrial, medical and consumer applications. The inherent salient features of this inverter-type fluid heating appliance are schematically presented as compared with other electrical heating schemes. Its operating characteristics in steady-state are illustrated and evaluated in experiment as well as computer simulation results. The promising applications of this fluid heating appliance are mentioned.","PeriodicalId":173172,"journal":{"name":"Proceedings IEEE Conference on Industrial Automation and Control Emerging Technology Applications","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117175426","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}
