6.Development trend of induction heating devices
The induction heating device consists of two parts, one is the AC power supply that provides energy, also called the variable frequency power supply, and the other is the induction coil and mechanical structure that completes the electromagnetic induction energy conversion, called the induction furnace. The variable frequency power supply has the division of power frequency, intermediate frequency and high frequency.
