What is the role of the induction coil and the power supply of the high-frequency induction heater
As we all know, the high-frequency induction heater is composed of an induction coil and a power supply, so what role does the induction coil and the power supply play?
The role of the induction coil: through the induction coil of the medium and high frequency alternating current around the coil to produce the same frequency and high density of the alternating magnetic field, if the alternating magnetic field is placed in the metal material, then the magnetic field line of the alternating magnetic field will cut the metal material, producing a large eddy current in the metal material. Eddy currents flow through the metal, and the metal resistance heats up, thus heating up the metal material. In the electromagnetic induction heating system, the induction line is a power output device.
The role of induction heating power supply: Induction heating power supply is a power supply device that converts the power frequency 50HZ alternating current into medium and high frequency (above 20khz to 200khz).
First of all, the three-phase power frequency alternating current is rectified into direct current, and then the direct current is adjusted into the middle and high frequency current, the capacitor of the working loop and the induction coil are supplied to form the middle and high frequency alternating current flowing through the induction coil. In electromagnetic induction heating system, induction heating power supply is a frequency converter and energy conversion device.
