The invention discloses an electromagnetic heating device and its heating control method and device. The driving circuit of the electromagnetic heating device drives a power switch tube according to a PPG control signal. The method includes the following steps: sampling the power supply voltage of the electromagnetic heating device to generate a voltage sampling value; when it is determined according to the voltage sampling value that the supply voltage is in a preset low-voltage range, obtain the current power level of the electromagnetic heating device and the target current corresponding to the current power level; according to the corresponding target The current controls the PPG width of the PPG control signal, so that the operating current of the electromagnetic heating device is maintained at the target current, so that when the power supply voltage is low, the heating control is realized through the current control method, and, by setting for each power level The corresponding target current can realize the adjustment of heating power at low voltage, improve the resolution of power at low voltage, effectively protect the power switch tube, and improve the reliability of the equipment.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to a heating control method for electromagnetic heating equipment, a heating control device for electromagnetic heating equipment, and an electromagnetic heating equipment. Background technique [0002] For areas where the power supply system is unstable, the voltage is often too low during peak power consumption, for example, the voltage will be around 160V. In order to ensure the reliability of the electromagnetic heating equipment, it is usually operated at a fixed power level such as the highest gear when the voltage is low, so that the user cannot adjust the power level, and the heating power of the electromagnetic heating equipment remains unchanged. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide a he...
