Eddy current dual packs heater based continuous pipeline fluid heating using soft switching PWM high frequency inverter

This paper presents an innovative prototype of a new conceptual electromagnetic induction eddy-current based fluid heating appliance using voltage-fed quasi resonant zero voltage soft switching PWM high-frequency inverter using IGBTs, which can operate at a constant frequency variable power regulation scheme. The promising simple high-efficient low noise inverter type electromagnetic induction eddy-current based pipeline fluid heating appliance is proposed for a saturated steam generator, superheated steam generator, hot water and hot air producer and metal catalyst heating for exhaust gas cleaning in engines. Under this technological background, a novel electromagnetic induction eddy-current dual packs heater (DPH) based pipeline fluid heating incorporates thin metal layer type package for continuous fluid heating appliances applying two types of voltage-fed quasi-load resonant ZVS-PWM high frequency inverter. The unique features of a novel electromagnetic induction eddy-current DPH based continuous pipeline fluid heating appliance is illustrated on the basis of simulation and discussed for the steady-state operating characteristics and experimental results.
