Noise reduction method and equipment for single-tube multi-head induction cooker and storage medium

The invention relates to the technical field of noise reduction of induction cookers, and discloses a noise reduction method and device for a single-tube multi-head induction cooker and a storage medium, and the method comprises the steps: determining a main furnace end and a slave furnace end according to the target power of each furnace end, carrying out the adjustment through a PPG mode, calculating the deviation frequency of the oscillation frequencies of the two furnace ends, and obtaining the noise of the single-tube multi-head induction cooker. The main furnace end adjusts the pulse width of the first PPG signal so that the first power of current operation can be consistent with the target power of the main furnace end, the auxiliary furnace end maintains the deviation frequency within the set frequency range by adjusting the pulse width of the second PPG signal, and the target power of the main furnace end can be adjusted by adjusting the chopping duration. The second power of the current operation is
