Enhanced high frequency heating machine, due to their high-frequency characteristics (usually between tens of kilohertz to 1 megahertz), are particularly suitable for precision surface treatment and rapid heating of small workpieces. This induction heating power supply can be applied in the following areas:
Surface Hardening: Used to increase the hardness and wear resistance of the surface of metal workpieces, suitable for parts such as gears and bearings.
Welding: Used for precision welding operations, such as jewelry, small parts, or welding points that require delicate manipulation.
Metal Melting: Suitable for the melting of small batches of precious metals or special alloys.
Medical Device Sterilization: Utilizes the thermal effect of high-frequency currents for the rapid sterilization of medical devices.
Electronic Component Heating: Used in electronics manufacturing for the rapid activation or repair of electronic components.
Heat Treatment: Including processes such as annealing and normalizing for induction heating treatment to improve the internal structure and properties of metals. The induction annealing is a key technique in this area.
Non-Destructive Testing (NDT): In some NDT applications, high-frequency induction heating can be used to detect internal defects in materials.
As a high frequency induction heating equipment factory, the high-frequency operation of high-frequency induction heating power supplies provides deeper levels of heating control, making them very popular in industrial applications that require precise and rapid heating.

Digital intelligent control offers several advantages over analog control systems, particularly in the stability of the DSP-based intelligent induction heating power supply across various environments. This technology enables the IGBT to operate at the optimal soft switching state, which optimizes parameters such as switching loss, voltage and current impact, and local temperature rise. It prevents a decrease in inverter efficiency that can occur when the inverter state deviates from the optimal condition and addresses issues like accelerated IGBT aging, such as unexplained damage after one year of use, and high maintenance costs in the later stages.
Ultra-high precision control is achieved through the use of the second-generation high-performance precise algorithm in power frequency control technology. All control processes, data processing, and parameter calculations are performed at high speed within the intelligent chip. Frequency tracking is lossless and drift-free, with control accuracy reaching the nanosecond level. Combined with proprietary load matching testing techniques, real-time tracking displays the load matching condition, ensuring that the equipment is always within the best power factor range.
Intelligent protection features a comprehensive set of fault judgment and protection circuits. In situations such as unstable cooling water pressure, excessively high temperatures, default three-phase power, or when a cold workpiece meets the induction coil (grounding protection condition), the power supply inverter can ensure output power. If the power supply encounters adverse conditions during normal heating operation, it can separately judge various protection signals and issue fault alarms, such as over-voltage, over-current, frequency limit, and IGBT fault alarm signals, which can help users find the source of the trouble.
Sealed protection uses sealing tape, in conjunction with the groove box edge, to achieve a high-level IP54 protection rating. Dust, moisture, and soot cannot enter the cabinet. The equipment can be used for a long time even in harsh environments, keeping the internal environment clean and ensuring that all electronic devices always perform at their best.
