Embodiment Construction
[0050] The invention is applied to existing induction heating equipment.
[0051] as attached figure 1 As shown, the DSP intelligent control algorithm of the induction heating power supply: it has task call core, AD data processing module, start-stop control module, communication management module, key processing and alarm module, interrupt module; the task call core controls AD data processing module, start-stop The control module, communication management module, button processing and alarm module perform task scheduling, and arrange the occupancy level of each module for the main control chip; when the interrupt module is triggered and executed, the main control chip is forcibly occupied.
[0052] Task call core:
[0053] The core of the task call adopts the cycle occupancy method to control the AD data processing module, start-stop control module, communication management module, and key processing module to occupy the main control chip cycle. The specific process is as f...

Induction heating power supply DSP intelligent control system: it has a task call core, AD data processing module, start and stop control module, communication management module, key processing and alarm module, and interrupt module. Induction heating power supply DSP intelligent control system: it has a task call core, AD data processing module, start and stop control module, communication management module, key processing and alarm module, and interrupt module. The present invention controls the output power of the power supply by automatically controlling the duty ratio of the chopping PWM signal through the control system to ensure constant power supply of the induction heating equipment; automatically controls the frequency of the inverter PWM signal to control the output frequency of the power supply to ensure the power supply of the induction heating equipment constant frequency. Improve production process level through constant mains power and mains frequency.
Description
technical field [0001] The invention relates to the field of induction heating control, in particular to an induction heating power supply DSP intelligent control system. Background technique [0002] Induction heating is to pass an alternating current into the induction coil, and use the principle of electromagnetic induction to generate eddy currents inside the heated material (that is, the workpiece), and rely on the energy of these eddy currents to heat the workpiece. The electric energy is transferred to the workpiece to be heated, and then the electric energy is converted into heat energy inside the metal. The induction coil is not in direct contact with the workpiece to be heated, and the energy is transmitted through electromagnetic induction. It was discovered at the beginning of the 19th century, and then because people realized the various hazards of electromagnetic induction in power generation, power transmission and the application of electrical equipment, they...
