Implementation of an Induction Furnace for Copper Melting

This research deals with the implementation of a designed power supply and induction coil for copper melting. The power supply is a voltage fed single phase inverter. The load is an induction coil connected in series with a low ESR capacitor as a tank circuit. The matching unit between the power supply and the load is a step down ferrite transformer. The induction coil and the melting process is simulated using 3D electromagnetic-thermal coupled analysis using the ANSYS software. Simulation and practical results shows the impact of the circuit components on the furnace performance discussed in this research. The achievement in this research is to approve the agreement between the practical results and those of the simulation, besides some valuable recommendations to improve the furnace performance are mentioned.
