Induction Heating Resonant Frequency

It is also very efficient since the heat is actually generated inside the workpiece. Resonance circuit coil capacitor must be driven at its resonant frequency.

The skin effect increases the effective resistance of the metal to the passage of the large current.

Induction heating resonant frequency. The resonance tank in an induction heating system is normally a parallel set of capacitor and inductor which resonates at a certain frequency. Large currents are forced through the object which is to be heated. It uses high frequency electricity to heat materials that are electrically conductive.

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. Inducing heat electromagnetically rather than using a heating element in contact with a part to conduct heat as does resistance heating. Since it is non contact the heating process does not contaminate the material being heated.

Coil generates high frequency magnetic field and the metal object in the middle of the coil induces eddy currents that heat it. Since the frequency is optimized at significantly high level ensures a maximum possible heat on the metal. The object is often called a work piece and the heating coil a work coil.

Therefore it greatly increases the heating effect caused by the current induced in the workpiece. This skin effect forces the alternating current to flow in a thin layer towards the surface of the workpiece. An induction heater consists of an electromagnet and an electronic oscillator that passes a high frequency alternating current ac through the electromagnet.

Induction heating is a non contact heating process. Where l is the inductance of the induction coil and c is the capacitance. Induction heating systems employ non contact heating.

In parallel with the coil is plugged resonance capacity to compensate its inductive nature. And the induction coil is subjected to a high frequency together this results in the generation of a proportionately intense amount of heat on the vessel. The principle of induction heating is simple.

The frequency is obtained from the following formula. Induction heating is heating conductive metals with no physical contact by using high frequency electricity. Series resonant induction heater.

An induction heater for industrial steel strip surface annealing has been implemented using the above approach 59 at a resonant frequency of 100 khz operating with 12 kv igbt modules. In addition to this the high frequency used in induction heating applications gives rise to a phenomenon called skin effect. A 50 kw series resonant power supply for melting forging and surface hardening applications has also been reported with a resonant frequency of 150 khz 60.

There is no one resonance frequency that will work better than any other. Red hot bolt run time of about 1 minute about 120 khz. This paper presents a technique to calculate the parameters of the coil to be used to heat an iron piece of given parameters to 850 oc.

Rather there is possibly an increase in magnetic coupling efficiency with increase in frequency then a decrease with further increase of frequency as losses skin effect capacitive interwinding coupling etc increase. Induction heating is not a resonance phenomenon.
