Conversor quase-ressonante para sistema de aquecimento por indução de uma carga ferromagnética

Abstract

This monografy, work deals with the development of a heating system by induction of a specific ferromagnetic charge. From the geometry and the intrinsic properties of the material, such as magnetic permeability and electric conductivity of the load, the relationship between the frequency of operation and the heat generation in the load was defined. A quasi-resonant circuit, switched with ZVS strategy, for induction heating ferromagnetic charges of high electrical resistivity, powered by pulsed, uncontrolled DC source was designed using the software LTSPICE and implemented, the obtained results are presented and discussed after the simulations.
