Design of channel induction furnace using IGBT technology

The design of induction furnace is presented with purpose to introduce new control theory that is "the design of channel induction furnace using IGBT technology". The experimental furnace is the unit that operates on 10-1000 Hz frequency. The power electronics converter provides current, power and consequently temperature regulation through voltage and frequency variation. The circuit is mainly consisting of power converter, induction furnace and induction heating. This paper presents the design and implementation of a parallel resonant inverter and parallel resonance tank operating at low frequency and high current for induction heating application. The main advantage of this work is focused in applying power electronics, particularly a parallel resonant inverter based on IGBT switching and a parallel RLC load matched with coupling transformer.
