How does an induction heater work?
An induction heater consists of an electromagnet and an electronic oscillator that passes a high-frequency alternating current (AC) through the electromagnet. The rapidly alternating magnetic field penetrates the object, generating electric currents inside the conductor, called eddy currents.
What are the two methods of induction heating?
Methods of Induction Heating Hysteretic heating occurs in a component up to the Curie temperature when the material’s magnetic permeability decreases to 1 and hysteretic heating is reduced. Eddy current heating constitutes the remaining induction heating effect.
What materials can be induction heated?
Induction heating is a fast, efficient, precise and repeatable non-contact method for heating electrically-conductive materials such as brass, aluminum, copper or steel or semiconducting materials such as silicon carbide, carbon or graphite.
How can I increase my induction heater power?
The induction coil efficiency upon heating of a steel wire can be increased by increasing its magnetic permeability. This can be achieved by increasing the current frequency and decreasing the magnetic field, which leads to an increase in the induction coil length at a constant power.
How do you control induction heating?
Induction heating coil can be controlled by single phase sinusoidal pulse width modulation (SPWM) digital signal processor (DSP)-based inverter. DSP is used to store the required commands for generating the necessary waveforms to control the frequency
Will an induction heater work on stainless steel?
Induction cooking surfaces work well with any pans with a high ferrous metal content at the base. Cast iron pans and any black metal or iron pans will work on an induction cooking surface. Stainless steel pans will work on an induction cooking surface if the base of the pan is a magnetic grade of stainless steel.
What is induction furnace principle?
In an induction furnace, the metal charge material is melted or heated by current generated by an electromagnetic field. When the metal becomes molten, this field also causes the bath to move. This is called inductive stirring.
How hot can induction heating get?
Induction heating is used in processes where temperatures are as low as 100 ºC (212 °F) and as high as 3000 °C (5432 °F). It can be used in brief heating processes that are on for less than half a second and in heating processes that are on for months.
Which type of heating has maximum power factor?
Explanation: Resistance heating is based on I2R effect and highly resistive in nature that’s why it has maximum pf. 6
On which principle induction heating process is based?
The induction heating works on the electromagnetic induction principle. Moreover, it is also known as eddy current heating.
What is induction cooling?
A method is described for cooling conductive channels to below ambient temperature. The thermodynamic induction principle dictates that the electrically biased channel will cool if the electrical conductance decreases with temperature.
