CONVERTER WITH SIMULTANEOUS BIFREQUENTIAL OUTPUT FOR INDUCTION HEATING.

摘要

Converter with simultaneous bifrequency output for induction heating. It contains a single inverter (3) whose output is connected to a single resonant circuit (4) of four reactive components capable of generating a current resulting from simultaneously superimposing two different frequencies. By feeding this current to a single coil, a magnetic field is generated that allows special induction heating. It has at its input a rectifier circuit (1) of the mains voltage (2), an intermediate energy storage device, an inverter circuit (3), an output resonant circuit (4), a heating inductor (5) and an auxiliary power supply unit, regulation, supervision, display, cooling and communication (6). It allows to independently regulate the power of each of the two components of different frequency present in its output. It can be applied, among others, for the induction heating of complex surface parts such as gears or sprockets.
