SIMULATION OF THE INDUCTION HEATER SUPPLIED FROM THYRISTOR INVERTER

The classical methods of designing induction heaters, usually supplied from the network or machine medium frequency generators, require the following assumption to be made: the voltage at the terminals of the coil is sinusoidal; the frequency of the voltage, the power surface density or the density of the heating flux, the material properties of the charge are constant and the electromagnetic and the temperature fields are considered to be uncoupled.
