Introduction to the intermediate frequency heating furnace: The intermediate frequency heating furnace adopts the induction heating process, and the induction heating is to directly heat the workpiece. The traditional power electronic devices used in induction heating equipment are electron tubes and fast thyristors. The tube has high voltage, poor stability, strong radiation, and low efficiency. It has reached the edge of elimination, but it has a high frequency and high power, so it still has a place in the market. Fast thyristors are the main force in current applications. They have high withstand voltage, large current, and strong ability to resist overcurrent and overvoltage. But it can only work below 10000Hz, which limits its scope of use. High-frequency heating furnace adopts IGBT as the main device. IGBT is a composite power device. It integrates the advantages of bipolar power transistor and power MOSFET. It has voltage-type control, large input impedance, small driving power, and simple control circuit. The switching loss is small, the on-off speed is fast, the operating frequency is high, and the component capacity is large. It not only reaches the frequency that the thyristor cannot reach (above 60kHz), but also gradually replaces the fast thyristor. 1kHz ~ 80kHz induction heating abroad has been widely used IGBT, which is the development direction of induction heating power supply.
