Product Description

Our enhanced and intelligent High Frequency Induction Heating IGBT Power Supplies use the new generation power electronic device IGBT power as switching devices in series resonant inverter power supply. Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, through heat generated in the object by eddy currents (also called Foucault currents).

An induction heater consists of an electromagnet and an electronic oscillator that passes a high-frequency alternating current (AC) power supply through the electromagnet. The rapidly alternating magnetic field penetrates to the object and generates electric currents inside the conductor called eddy currents. The eddy currents that are flowing through the resistance of the material heat it by Joule heating. The frequency of the current used depends upon the object size, material type, coupling (between the work coil and the object to be heated) and the penetration depth.

One of the most important features of this process is that the heat is generated inside the object itself, instead of an external heat source via heat conduction. Thus objects can be heated very rapidly. In addition, there will be no need for any external contact that can be important where contamination is an issue. Induction heating is applied in many industrial processes, like zone refining used in the semiconductor industry, heat treatment in metallurgy, Czochralski crystal growth, and to melt refractory metals which require very high temperatures.

Inductive heating power supply applications

Applications include surface hardening, brazing, melting, and soldering and heating to fit. Iron and its alloys respond best to the induction heating, due to their ferromagnetic nature. Eddy currents can be generated in the conductor and magnetic hysteresis can generate in any magnetic material.

Induction heating has been used to heat liquid conductors (such as molten metal) and also gaseous conductors (such as gas plasma). It is often used extensively in the semiconductor industry for the heating of silicon and other semiconductors, such as Silicon carbide (SiC), Gallium Arsenide (GaAs), Sapphire growth, Indium Phosphide and is used to heat graphite crucibles (containing other materials).
