The trend of induction heating equipments 

The induction heating equipment contains two parts: AC power supply that provides energy which is known as the frequency conversion power supply,and the other part is the induction coil and mechanical structure that complete the electromagnetic induction energy conversion, called the induction heating furnace as well. 

1.High frequency heating equipment 

In order to achieve frequency conversion from power frequency 50hz to high frequency 70K~1000Khz, ususaly using a vacuum tube high frequency generator. 

2.Intermediate frequency heating equipment 

Through the adoption of low factor intermediate frequency generator and thyristor inverter, for converting line frequency 50hz into intermediate frequency (500~10000Hz), also called electrical energy device. 

3.Line frequency induction heating equipment 

The inductor frequency for power supply is same as power grid which is 50Hz. So it can obtain energy from power grid directly, the disadvantage is that the power factor is low. 

With the development of market demand, the development of induction heating devices shows that the power supply becomes higher frequency with the large capacity of power electronic power devices, the control simulation of electronic technology devices are tending to digitization, automatic control tending to intelligent development.

(1)The induction heating power supply tend to large-capacity

The medium frequency induction heating mainly apply for thyristors; IGBT is mainly used in super audio segment. And the high frequency was originally using SIT, and now the mainly developing MOSFET power supply. Power supplies using IGCT are also starting to presence in the market. The demanding for high-frequency power supplies has fostered new power devices, and new electronic devices have in turn promoted the development of high-frequency power supplies. Large capacity of induction heating power supply, such as tens of megawatts, hundreds of megawatts, shall be achieved. 

(2)Induction heating device toward mechanization, automation 

In recent years, with the rapid development of mechatronics, computers, information and control, equipment automation, new materials, new processes, casting, forging and heat treatment processes tend to be digital and precision. The trend of heating treatment is reflected in the following: digital manufacturing is integrated into the casting and forging process, including heating and melting equipment; Casting and forging short process production requires less waste of resources; Large-scale casting and forging production requires industrial energy saving; Cleaner production under automatic control. Therefore, induction heating equipment in its energy-saving and environmental protection characteristics, there is a trend of market demand to large-scale, automation and control trend toward intelligent direction.

Therefore, induction heating equipment with its energy-saving and environmental protection characteristics is trending to large-scale, automation and control trend toward intelligent direction.
