The high-power IGBT intermediate frequency power supply produced by Forever Electromechanical adopts IGBT full bridge inverter and zero voltage soft switching mode to ensure the reliability of IGBT. The turn-on loss is extremely low, and the efficiency is as high as 98%. It also has various comprehensive protection functions to ensure that the internal components of the power source are not damaged under any circumstances. The working principle of KGPS intermediate frequency power supply is to use a three-phase bridge fully controlled rectification circuit to rectify AC power into DC power. After being smoothed by a reactor, it becomes a constant DC current source. Then, through a single-phase inverter bridge, the DC current is inverted into a single-phase intermediate frequency current of a certain frequency (usually 1000 to 8000Hz). The load consists of an induction coil and a compensation capacitor, connected in a parallel resonant circuit.

high reliability

High reliability of intermediate frequency induction heating power supply:

1. Intelligent protection system: adopting diode special protection technology, never burning the diode; Adopting IGBT high-speed protection technology to extend the lifespan of GBT; Transformer primary side, capacitor, and output busbar ignition protection; Workpiece or steel billet contacts the sensor for ignition protection (grounding protection). Users can also choose customized IGBT intermediate frequency power protection solutions based on various operating conditions;

2. DSP digital control device, parameters are fixed in the program, and environmental changes will not affect internal parameters. The digital intermediate frequency induction heating power supply has the advantages of high stability, fast transmission speed, high accuracy, and easy process adjustment. It has a single main control board, high integration degree, and few fault points;

3. The IGBT intermediate frequency power supply uses internationally renowned brand components and fully fiber optic transmission signals to avoid interference and ensure more stable operation of the induction heating equipment;

4. Good resistance to voltage fluctuations: When the voltage fluctuation range is between 350-440V, the output power of the intermediate frequency induction heating power supply fluctuates; 1&permil; It does not affect the quality of the product.
