The human-machine interface of visibility makes the operator feel friendly and intuitive. Thanks to its rich industrial interface, it is more powerful and flexible to match with robots, various automation devices, and remote (unmanned) devices. We use digital soft-switching technology to make the machine work more efficiently and lower its own loss, so that the working frequency can be made higher, and the application of the device is expanded.
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.
