Electromagnetic Induction based Continuous Fluid Heating Appliance using Soft Switching PWM High Frequency Inverter

摘要

This paper presents an innovative product of induction heated fluid heating appliance using voltage source type quasi-resonant ZVS-PWM high frequency inverter which incorporates 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 by 4kW breadboard appliance designed for fluid heating appliance in the pipeline systems. The promising cost effective high efficient inverter fed fluid heating appliance using the latest IGBTs is proposed for induction heating boiler, super heated steam generator, hot gas producer, super heated steam cleaner and dryer, metal catalysis heating for exhaust gas cleaning in engine acceptable for industrial, chemical and automotive systems and consumer heat energy processing applications.
