Design and Implementation of a Low Losses Current-Fed Portable Induction Furnace

Abstract

This research is concentrated on the practical design of a portable Induction Heating Furnace (IHF) composed of a Current-Fed Parallel Resonance Inverter (CFPRI) as a power supply of an Induction Coil (IC) and its specimen. The design is intended to reduce the losses in both the switches of the inverter and those due to non-sinusoidal currents in the conductors connecting the power supply components. The IC was connected in parallel to a suitable capacitor to form a tank load in this furnace. Detailed design steps for each implemented part are represented in this research. The implemented power supply tested practically on certain load. The practical results were compared with that obtained from the simulation for this system using the (Plecs) computer package. The practical results agreed with the simulation.
