Simulation of Induction Furnace and Comparison with Actual Induction Furnace

Abstract

In this paper, at first, a matlab simulation of induction furnace model optimized resonant capacitor is designed for a practical induction furnace with parallel resonant inverter. Then rectifier and inverter snubber circuit are designed and voltage, current, THD and power were measured. This measured value is compared with actual working industry furnace data and conclusion is made that when furnace is not operate at full load that time its power factor is very low and THD is high.
