Induction heatingof electric heater

The conductor itself is heated by the thermal effect formed by the induced current (eddy current) in the alternating electromagnetic field of the conductor. According to different heating process requirements, the frequency of the AC power supply used for induction heating includes power frequency (50-60 Hz), intermediate frequency (60-10000 Hz) and high frequency (above 10000 Hz). The power frequency power supply is an AC power supply commonly used in industry. The power frequency of most countries in the world is 50 Hz. The voltage applied to the induction device by the industrial frequency power supply for induction heating must be adjustable. According to the heating device power and the power supply network capacity, you can use a high-voltage power supply (6 ~ 10 kV) to supply power through a transformer; you can also directly connect the heating device to a 380-volt low-voltage power grid.
