High frequency eddy current-based fluid heater using soft-switching inverter

Abstract

This paper presents a new generation product of induction fluid heating appliance using a novel voltage source type quasi-resonant ZVS-PWM high frequency inverter which incorporates a constant frequency variable power regulation scheme. Its operating principle and unique features are illustrated and evaluated on the basis of computer simulation and experimental results implemented on a 4 kW breadboard systems designed for moving fluid heating appliance in pipeline systems. The promising cost effective high efficient inverter-fed fluid heating appliance in pipeline plants is proposed from a practical point of view for induction heating boiler super heated steam generator, hot gas producer and metal catalysis heating for exhaust gas cleaning in an engine acceptable for industrial, chemical systems and consumer heat energy processing appliances.
