INVESTIGATION INTO SATURABLE TRANSFORMERS FOR INDUCTION METALLURGY APPLICATION

Abstract

For induction metallurgy we used to apply different semiconductor converters in order to get higher frequency to the magnetic field that will later be the source for the eddy currents. The purpose of this research is to use the characteristic of the magnetic materials for building the saturable transformers. These transformers will in one hand avoid the higher cost of the semiconductor module in the equipment and in other hand offer the equipment the voltage and current source with the higher harmonics. Using the software Matlab we have got the satisfactory results that can help us to build later a model of the equipment for this kind of the industrial manufacturing.
