Recommended induction heating equipment for DSP+ FPGA full digital control melting and diathermy Compared with the advantages of traditional analog series resonance induction heating equipment:

1. In terms of core control :

For traditional analog power supplies, the parameters are determined by analog devices such as potentiometers. These devices are relatively affected by the environment, and temperature changes may cause parameter changes; the control process, data processing, and parameter storage of the DSP intelligent induction heating power supply are all in digital form The environment changes will not affect the calculation output process. Corresponding to the analog control system, the all-digital power supply has higher stability in different environments.

2. In terms of touch screen display :

The DSP intelligent induction heating power supply displays the working status and working parameters of the equipment on the touch screen LCD, and the working details of the equipment are clear at a glance.

3. In terms of fault self-diagnosis and processing :

The DSP intelligent induction heating power supply displays the fault location and treatment method. When an error occurs or an alarm occurs in a special working condition, the touch screen will display the fault content. Click the help of the corresponding fault to find the corresponding fault solution. More than 90% of the common faults can be dealt with quickly by the operators, which greatly improves the production efficiency and reduces the dependence on the technical level of the operators.

4. In terms of intelligent protection system :

Traditional analog power supplies only have simple protection functions such as over-current and over-voltage. The DSP intelligent induction heating power supply has a wealth of fault judgment and protection circuits. When the cooling water pressure is unstable, the temperature is too high, the three-phase power is missing, and the cold workpiece touches the inductor (ground protection), etc., it can ensure that the power inverter stops outputting power; the real-time monitoring system always ensures that the IGBT is working The optimal soft switching state minimizes the parameters such as switching loss, voltage and current impact, and local temperature rise, which not only avoids the reduction of inverter efficiency caused by the deviation of the inverter state from the best, but also solves the aging acceleration of IGBT (such as using a Inexplicable damage after a year) and high maintenance costs in the later period; if the power supply suddenly encounters bad working conditions during normal heating work and the bad working conditions cannot be automatically restored in a short time, various protection signals can be judged and fault alarms can be issued, such as: Alarm signals such as over-voltage, over-current, frequency overrun, and IGBT failure can assist users in finding and troubleshooting the source of the failure.

5. In terms of work efficiency :

When the total power is unchanged, the output voltage is only half of the ordinary series resonant machine, which is safer; the output current is doubled, and the heating effect is better.

Advance : Remote control function (RS-232C or RS-485/CAN Interface, Connect with computer, PLC) and be controlled by a digital circuit. The power adjustment can be adjusted from 0% to 100%. The resolution is 0.1% or 0. 01%. The output stability can reach 0.3% or 0. 025%; configure digital PID temperature control module at the same time.

Operating Principle

Frequency conversion electromagnetic induction heating or induction heating for short is a method for heating metal materials by converting power frequency power supply into that of specific range based on the principle of electromagnetic induction. It is mainly applicable to the metal hot working, heat treatment, welding and melting. This type of heating technique is also applicable to packing industry (such as sealing of aluminum foil used in medicine and food industry), semiconductor material (such as extruded monocrystalline silicon and heated affixing metal parts for auto glass). 

Basic components of induction heating system include induction coil, AC power source and work pieces. Induction coil can be fabricated into different shapes as per different heated objects. The coil is connected with the power source providing alternating current for coil. The alternating current possessed by the coil can create a alternating magnetic field passing through the work pieces to produce eddy flow as required by heating.

Advantages of Induction Heating Equipment

1. Fast heating: the minimum rate of heating is less than 1 second (rate of heating is available for adjustment and control).

2. Wide coverage of heating: it can be used to heat various metal parts (replace removable induction coil as per different operating switches).

3. Easy installation: it can be used once it is connected with power source, induction coil as well as water supply pipe and rising pipe; it is small in size and light in weight.

4. Easy operation: you can learn to operate it within several minutes.

5. Fast start-up: it can be started to perform heating operation on condition that water and power supply is available.

6. Low power consumption: As compared with conventional vacuum tube high frequency equipments, it can save the power by approximately 70%. The smaller the size of the work piece is, the lower power consumption would be.

7. High effectiveness: it has such features as uniform heating (it is applicable to adjust the spacing of the induction coil to ensure the appropriate temperature as required by each part of work piece), fast warming and limited oxic horizon, and can guard against any waste after annealing.

8. Comprehensive protection: it has such functions as overpressure, over-current, overheat and water shortage alarm indications as well as automatic control and protection.

9. Controllable temperature: it is applicable to control the temperature for heating work pieces as per the preset heating time, and thereby control the heating temperature at a certain technical point.

10. Comprehensive full load design: it can work continuously for 24 hours.

11. Small size and light weight: it has a weight of only several dozens of kilograms, of which, the limited floor space can effectively save the workshop space.

12. Elimination of high voltage: it requires no step-up transformer which may produce approximately ten thousand voltage, and thus can ensure the maximum safety.
