description The invention provides a power control method of an electromagnetic heating device. The method comprises the following steps: judging whether target heating power is greater than a preset value; adjusting a switching circuit to control a rectifying circuit to output full-wave rectified waveform when the target heating power is greater than the preset value, and enabling the controller to send outa control signal to drive the connection of the power tube, thereby enabling a resonance circuit to work; when the target heating power is less than the preset value, adjusting the switching circuit to control the rectifying circuit to output half-wave rectified waveform, and then enabling the controller to send out the control signal to drive the connection of the power tube at the subsequent t1moment, thereby enabling the resonance circuit to work, wherein the t1 moment is the moment without waveform output of the half-wave rectified waveform, or the moment after the half-wave rectified waveform at least experiences
