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 saturated steam generator, superheated steam generator, hot water and hot air producer, metal catalyst heating for exhaust gas cleaning in engine. Under these 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.
