1. What’s the principle of induction heating?

The principle of induction heating is mainly based on two well-known physical phenomena:
<1> Electromagnetic induction
<2> The joule effect.

2. What is the importance of a power supplies power rating and frequency?

The power rating determines the speed at which a workpiece can be heated. The frequency, along with the electrical resistivity of the workpiece and relative magnetic permeability, determines the skin depth of the eddy currents induced into the work piece. In surface heating, the power rating also plays an important role in skin depth. The higher the frequency, the more shallow the skin depth and the lower the frequency, the deeper the skin depth. Therefore, higher frequencies are more effective for heating smaller parts or parts that require shallow heat penetration, while lower frequencies are more effective for larger materials with deeper heat penetration requirements.
