Main Characteristics:

The full-digital induction heating power supply has a good and reliable assembly process to withstand the toughest production environments. Mainly composed of the following parts:

1. Full digital control, using DSP+FPGA to realize digital phase-locked loop control, the whole motherboard has few peripheral circuits except DSP chip and FPGA chip, which completely solves the performance fluctuation caused by temperature and parameter drift of traditional analog circuit. Extremely stable.

2. Mature technology, digestion and absorption of foreign advanced technology, cleverly designed a phase difference synchronous feedback loop, high startup success rate (100%), high machine efficiency (> 95.%);

3. Good control performance, wide frequency range , smooth and continuous power adjustment (0.1-100% rated power), load using series or parallel inverter resonant circuit, simple circuit, reliable operation, easy adjustment, adaptability to load Strong adaptability to a wide range, suitable for intermittent work and long-term work system, to meet the needs of industrial sites;

4. Frequency tracking using precise phase control method, advanced phase tracking algorithm, the phase is always optimal when heating workpieces of different sizes, which is better than similar products; at the same time, the device can display the matching degree of load in real time, when the matching degree is too bad, the device will Issue an alarm;

5. Due to the pre-stage power adjustment, the inverter circuit always works in the quasi-resonant state, the power factor is extremely high, the IGBT is naturally soft-switched, the whole inverter circuit has very little heat generation, and the conversion efficiency is high;

6. The dual-channel IGBT driver based on ASIC design has fault memory, fault soft shutdown and fault interlocking function to ensure IGBT work safety and never fry; the drive pulse signal from the main board to the drive board is transmitted by industrial optical fiber, which greatly improves the transmission. The reliability of the transmission, at the same time, achieves complete isolation between the main board and the main inverter circuit, and has good anti-interference ability.

7. The control circuit adopts international famous brand integrated circuit control, full patch design, and automatic placement machine welding to ensure the circuit board is stable and reliable.

8. The operation is simple, the power adjustment is only required to adjust the knob or given by the machine tool. It only needs to press the start and stop buttons during production. If it is connected with the machine tool, it can be automatically produced according to the program; at the same time, it can also be digitally set the output Power or current on the human-machine interface of the power supply ;

9. Perfect protection circuit and measures, overcurrent, overvoltage (parallel inverter), overheat protection, water temperature alarm, water pressure alarm, fuse alarm, gate alarm, frequency tracking loss lock, full-featured, protection Fast and reliable;

10. Provide dedicated low-voltage test function, which provides convenience for customer load matching and debugging. It can change the load at will, and the low-voltage circuit detects the load power resonance frequency matched by the user.

11. The human-machine interface adopts well-known brand 10 industrial touch screen, which can display the running status and parameters of the equipment in real time, such as voltage, current, power, frequency, inverter voltage, heating time, load matching degree, motherboard temperature and other parameters, and can be sampled and stored. At the same time, you can store thousands of heating processes, just call them when you use them;

12. The main board reserves RS485 and CAN, Ethernet and other communication interfaces for communication with the host computer, touch screen, PLC, etc.; ModbusRTU, ModbusTCP, Canopen communication protocol are supported by default;
