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}

In this paper, a high-frequency ZVS-PWM power amplifier which incorporates auxiliary TQRCP circuits into the bridge legs is developed for a magnetic-field current tracking control system.

Each bit of digital data is assigned to a frequency signal, and each multifrequency signal consisting of mixed frequency signals of 4 bits is fed to the respective FM modulator. An FM signal is mixed with another FM signal, and the mixed FM signals are fed to the VCO operating as the SWFM modulator at 20 MHz. The VCO output is fed to the electrical-to-optical (E/O) converter, and then sent to the GI optical fiber.
