This paper describes a newly-developed of an electromagnetic induction fluid heating appliance using a heatedflow-through metallic package incorporated into the nonmetallic vessel in the pipeline, which is composed of series-loaded resonant phase-shift PWM high-frequency inverter using IGBT modules and their optirum driver modules in addition to an auto-tuning PID controller for temperature regulation. This efficient inverter-fed type fluid heating appliance is more acceptable for high-quality heat energy transfer and delivery processing plants operated under a precise temperature control scheme as well as heat-energy storage and heat exchange processing plants because of clean, safty and high-efficient energy conversion, compactness in volumetric size, and ease to control. In particular, the series capacitor-compensated resonant PWM inverter with a power factor correction and active sinewave line current-shaping functions is introduced for induction-heated pipeline fluid healing. The original structure of electromagnetic induction-heated metallic package in the nonmetallic vessel or tank for high-efficient fluid heating is demonstrated from a practical point of view, in which specially-designed fluid-through induction-heating metallic package assembly with a huge heating surface to induce the eddy current is incorporated into the nonmetallic cylindrical vessel with a working coil connected to a high-frequency AC power supply. The inherent remarkable features of this power electronic appliance are schematically pointed out and confirmed. Its operating characteristics in the steady-state are illustrated and evaluated. The prospective applications of this new conceptional fluid heating appliance are mentioned herein.
