This paper presents a novel prototype of a new concepttonal electromagnetic induction fluid heating appliance with eddy current-based flow-through thin metallic heater assembly, which is composed of the voltage source-fed type phase-shifted PWM series-load resonant high-frequency inverter using IGBT modules and thek driver modules in addition to a temperature sensor, and an auto-tuning PID gain controller for precise and stable temperature regulation scheme.<br/> In particular, the efficient series capacitor-compensated load resonant high-frequency inverter system with a power factor correction and active sinewave line current shaping functions is introduced as this induction-heated fluid heating appliance in pipeline used for industrial, medical, chemical, consumer power processing apphca-tions.<br/> Its operating characteristics in steady-state are illustrated and evaluated in experiment and its computer simulation results. The promising cost effective applications of this induction-heated fluid-heating appliance are mentioned from a practical point of view.

This Paper the state-of-the art indirect induction heated boiler and induction heated hot air producer using the voltage-fed series resonant high-frequency inverter whice can operate in the frequency range from 20kHz to 50kHz. A specially-designed induction heater composed of laminated stainless assembly with many tiny holes and interconnected spot welding points between stainless plates is inserted into the ceramic type vessel with external working coil connected to the inverter and tubelence fluid through this induction heater to moving fluid generates in the vessel. The operating performances of this unique appliance in next generation and its effectiveness are evaluated and discussed from a practical point of view.
